          &lt;span class="library"&gt;&lt;a href="http://www.boost.org/libs/process/"&gt;Process&lt;/a&gt;:&lt;/span&gt;
  Process library by Klemens
          D. Morgenstern, that provides cross platorm ways to allows you to:
        &lt;/div&gt;
        &lt;ul&gt;
          &lt;li&gt;
            &lt;div&gt;
              create child processes
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              setup streams for child processes
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              communicate with child processes through streams (synchronously or
              asynchronously)
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              wait for processes to exit (synchronously or asynchronously)
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              terminate processes
            &lt;/div&gt;
          &lt;/li&gt;
        &lt;/ul&gt;
        &lt;div&gt;
          Broken feature:
        &lt;/div&gt;
        &lt;ul&gt;
          &lt;li&gt;
            &lt;div&gt;
              &lt;a href="https://github.com/klemens-morgenstern/boost-process/issues/67"&gt;GitHub
              #67: &lt;em&gt;"group.wait() does not return"&lt;/em&gt;&lt;/a&gt;.
            &lt;/div&gt;
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
    &lt;/ul&gt;
  &lt;/div&gt;
  &lt;div id="version_1_64_0.updated_libraries"&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Suppressed false warnings about returning reference to temporary
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                &lt;code&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;addressof&lt;/span&gt;&lt;/code&gt; is now used instead of
                directly taking the address &lt;a href="https://svn.boost.org/trac/boost/ticket/12615"&gt;#12615&lt;/a&gt;
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Headers are not included using double quotes any more &lt;a href="https://svn.boost.org/trac/boost/ticket/12053"&gt;#12053&lt;/a&gt;
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                CI tests now run with &lt;code&gt;&lt;span class="identifier"&gt;address&lt;/span&gt;&lt;/code&gt;,
                &lt;code&gt;&lt;span class="identifier"&gt;leak&lt;/span&gt;&lt;/code&gt;, and &lt;code&gt;&lt;span class="identifier"&gt;undefined&lt;/span&gt;&lt;/code&gt; sanitizers
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added more test
              &lt;/div&gt;
            &lt;/li&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed possible incorrect code generation in 64-bit atomic operations
                on 32-bit x86 with gcc versions older than 4.7 and compatible compilers.
              &lt;/div&gt;
            &lt;/li&gt;

            &lt;li&gt;
              &lt;div&gt;
                Added &lt;code&gt;&lt;span class="identifier"&gt;BOOST_NO_CXX11_SFINAE_EXPR&lt;/span&gt;&lt;/code&gt;
                defect detection.
              &lt;/div&gt;
            &lt;/li&gt;

  &lt;div id="version_1_63_0.post_release_patches"&gt;
    &lt;h3&gt;&lt;span class="link"&gt;Post-release Patches&lt;/span&gt;&lt;/h3&gt;

            &lt;li&gt;
              &lt;div&gt;
                Using 64-bit atomic operations on 32-bit x86 with gcc versions older
                than 4.7 and compatible compilers can result in generation of incorrect
                code. This problem is fixed in &lt;a href="https://github.com/boostorg/atomic/commit/a67cc1b055cf09f371e2eca544884634a1ccc886"&gt;this&lt;/a&gt;
                commit.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
    &lt;/ul&gt;
  &lt;/div&gt;
  &lt;div id="version_1_63_0.updated_libraries"&gt;
    &lt;h3&gt;&lt;span class="link"&gt;Updated Libraries&lt;/span&gt;&lt;/h3&gt;
    &lt;ul&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class="library"&gt;&lt;a href="http://www.boost.org/libs/atomic/"&gt;Atomic&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added the static constant &lt;code&gt;&lt;span class="identifier"&gt;atomic&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="identifier"&gt;T&lt;/span&gt;&lt;span class="special"&gt;&amp;gt;::&lt;/span&gt;&lt;span class="identifier"&gt;is_always_lock_free&lt;/span&gt;&lt;/code&gt;
                for conformance with C++17. The constant indicates that the given
                specialization always provides lock-free implementation of atomic
                operations.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Improved support of Oracle Studio on x86 targets.
              &lt;/div&gt;
            &lt;/li&gt;

                  &lt;li&gt;
                    &lt;div&gt;
                      Added a way to access the current file name from the text file
                      sink backend. The file name can be obtained with the &lt;code&gt;&lt;span class="identifier"&gt;get_current_file_name&lt;/span&gt;&lt;/code&gt; method.
                    &lt;/div&gt;

            &lt;li&gt;

                Bug fixes:
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Fixed compilation errors for Android API prior to version 21.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Streaming operators now take scalar types and enums by value.
                      This allows to output static constants and bitfields directly
                      into formatting stream and record stream. (&lt;a href="https://svn.boost.org/trac/boost/ticket/11998"&gt;#11998&lt;/a&gt;)
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Fixed auto-detection of native syslog API. (&lt;a href="https://svn.boost.org/trac/boost/ticket/12600"&gt;#12600&lt;/a&gt;)
                    &lt;/div&gt;

                  &lt;li&gt;
                    &lt;div&gt;
                      In UDP socket based syslog backend implementation, changed
                      the syslog message format for better compliance with RFC3164.
                    &lt;/div&gt;

                      File close handler installed in text file sink backend is no
                      longer called if the file is not open yet.
                    &lt;/div&gt;

                  &lt;li&gt;
                    &lt;div&gt;
                      The maximal string length limit has been increased to 2048

                  &lt;li&gt;
                    &lt;div&gt;
                      The maximal string length limit can be extended beyond 2048
                      by regenerating some of the Boost headers using a script (part
                      of the library)
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      The string length limit can be changed within a compilation
                      unit
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;

              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Activate BOOST_MOVE_FORCEINLINE
              &lt;/div&gt;
            &lt;/li&gt;

          &lt;span class="library"&gt;&lt;a href="http://www.boost.org/libs/optional/"&gt;Optional&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added two new in-place constructors. They work similarly to &lt;code&gt;&lt;span class="identifier"&gt;emplace&lt;/span&gt;&lt;span class="special"&gt;()&lt;/span&gt;&lt;/code&gt;
                functions: they initialize the contained value by perfect-forwarding
                the obtained arguments. One constructor always initializes the contained
                value, the other based on a boolean condition.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Syntax &lt;code&gt;&lt;span class="identifier"&gt;o&lt;/span&gt; &lt;span class="special"&gt;=&lt;/span&gt;
                &lt;span class="special"&gt;{}&lt;/span&gt;&lt;/code&gt; now correctly un-initializes
                an &lt;code&gt;&lt;span class="identifier"&gt;optional&lt;/span&gt;&lt;/code&gt;, just
                like in &lt;code&gt;&lt;span class="identifier"&gt;std&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;optional&lt;/span&gt;&lt;/code&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed &lt;code&gt;&lt;span class="identifier"&gt;optional&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="identifier"&gt;optional&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="identifier"&gt;T&lt;/span&gt;&lt;span class="special"&gt;&amp;gt;&amp;amp;&amp;gt;&lt;/span&gt;&lt;/code&gt;
                initialization. (&lt;a href="https://svn.boost.org/trac/boost/ticket/12203"&gt;#12203&lt;/a&gt;)
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Optional constructors are sfinae-friendly. This fixes interaction
                with &lt;code&gt;&lt;span class="identifier"&gt;std&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;tuple&lt;/span&gt;&lt;/code&gt;. (&lt;a href="https://svn.boost.org/trac/boost/ticket/12563"&gt;#12563&lt;/a&gt;)
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Most of modules now support C++11 variadic templates.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed type deduction failure with result type.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Suppress unused warnings.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed too few arguments error on binary math functions.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added workarounds for older compiler.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added (basic) support for C++11 (std::shared_ptr, std::unique_ptr)
              &lt;/div&gt;

  Boost QVM is a
          generic library for working with quaternions, vectors and matrices of static
          size with the emphasis on 2, 3 and 4-dimensional operations needed in graphics,
          video games and simulation applications, from Emil Dotchevski.

              &lt;div&gt;
                Improved support for Oracle Studio and SPARC. The library now provides

                Debug implementation is no longer used by default in debug mode.
                Debug implementation does not have the same thread safety guarantees
                as the normal (release) implementation or other containers. As a
                result of this change &lt;code&gt;&lt;span class="identifier"&gt;BOOST_CB_DISABLE_DEBUG&lt;/span&gt;&lt;/code&gt;

                    &lt;div&gt;
                      Added new tools for inter-process logging on a local machine.
                      The implementation includes a resource name wrapper, an inter-process
                      message queue and a sink backend.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added a new character decorator called &lt;code&gt;&lt;span class="identifier"&gt;max_size_decor&lt;/span&gt;&lt;/code&gt;.
                      The new decorator allows to limit the output of its adopted
                      formatter up to the specified length.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;

                    &lt;div&gt;
                      Fixed that logging streams could retain formatting settings
                      across different log records. (&lt;a href="https://svn.boost.org/trac/boost/ticket/12178"&gt;#12178&lt;/a&gt;)
                    &lt;/div&gt;
                  &lt;/li&gt;

                    &lt;div&gt;
                      Enabled all the special function code to work correctly with
                      types whose precision can change at runtime: for example type
                      &lt;code&gt;&lt;span class="identifier"&gt;mpfr_float&lt;/span&gt;&lt;/code&gt;
                      from Boost.Multiprecision.

                New features
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      dataset driven test-cases have now a unique name and all sample
                      tests of a dataset live inside the same test suite
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Boost.test learned a new command line switch, &lt;code&gt;&lt;span class="special"&gt;--&lt;/span&gt;&lt;span class="identifier"&gt;logger&lt;/span&gt;&lt;/code&gt;
                      for setting a test logger as well as its parameter in one command
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Boost.test learned to have several loggers at the same time,
                      each of which having their own log level and output stream
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Boost.test learned a new logger, &lt;code&gt;&lt;span class="identifier"&gt;JUNIT&lt;/span&gt;&lt;/code&gt;,
                      that is able to output Junit/xUnit compatible streams
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      It is now possible to specify several test filters through
                      the environment variable &lt;code&gt;&lt;span class="identifier"&gt;BOOST_TEST_RUN_FILTERS&lt;/span&gt;&lt;/code&gt;
                    &lt;/div&gt;

                of the type as &lt;code&gt;&lt;span class="keyword"&gt;const&lt;/span&gt; &lt;span class="keyword"&gt;char&lt;/span&gt;&lt;span class="special"&gt;*&lt;/span&gt;&lt;/code&gt;
                at compile time. So we can do a lot of interesting things at &lt;strong&gt;compile time&lt;/strong&gt;: check namespace of a type, sort
                types according to their lexical representation, check that type
                is a template type and so on... A few examples were provided.

            &lt;li&gt;
              &lt;div&gt;
                Dropped BOOST_VARIANT_NO_REFERENCE_SUPPORT macro and dropped support
                for compilers without SFINAE &lt;a href="https://svn.boost.org/trac/boost/ticket/12250"&gt;#12250&lt;/a&gt;

                Multiple minor fixes (typos, missing includes)

  Library for comfortable work
          with DLL and DSO. Library provides a portable across platforms way to:
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                load libraries
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                import any native functions and variables
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                make alias names for C++ mangled functions and symbols
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                query libraries for sections and exported symbols
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                self loading and self querying
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                getting program and module location by exported symbol
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;

          &lt;span class="library"&gt;&lt;a href="http://www.boost.org/libs/hana/"&gt;Hana&lt;/a&gt;:&lt;/span&gt;
  A modern C++ metaprogramming
          library. It provides high level algorithms to manipulate heterogeneous
          sequences, allows writing type-level computations with a natural syntax,
          provides tools to introspect user-defined types and much more.
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class="library"&gt;&lt;a href="http://www.boost.org/libs/metaparse/"&gt;Metaparse&lt;/a&gt;:&lt;/span&gt;
  A library for generating
          compile time parsers parsing embedded DSL code as part of the C++ compilation
          process. The library is similar to Spirit, however while parsers built
          with Spirit parse at run-time, parsers built with Metaparse parse at compile-time.
        &lt;/div&gt;
      &lt;/li&gt;
    &lt;/ul&gt;
  &lt;/div&gt;
  &lt;div id="version_1_61_0.updated_libraries"&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                More tests and maintainance fixes.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;

                &lt;code&gt;&lt;span class="identifier"&gt;small_vector&lt;/span&gt;&lt;/code&gt; supports
                more constructors and assignments.

                Now &lt;code&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;optional&lt;/span&gt;&lt;/code&gt; is specialized for reference
                parameters. This addresses a couple of issues:
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      the &lt;code&gt;&lt;span class="keyword"&gt;sizeof&lt;/span&gt;&lt;/code&gt; of
                      optional reference is that of a pointer,
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      some bugs connected to copying optional references are gone,
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      all run-time bugs caused by incorrect reference binding on
                      some compilers are now turned into compile-time errors,
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      you can swap optional references: it is like swapping pointers:
                      shalow, underlying objects are not affected,
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      optional references to abstract types work.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Documented nested typedefs (&lt;a href="https://svn.boost.org/trac/boost/ticket/5193"&gt;Trac
                #5193&lt;/a&gt;).
              &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;
                Made the perfect-forwarding constructor SFINAE-friendly, which fixes
                &lt;a href="https://svn.boost.org/trac/boost/ticket/12002"&gt;Trac #12002&lt;/a&gt;.
                However, this only works in the newer platforms that correctly implement
                C++11 &lt;code&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="identifier"&gt;type_traits&lt;/span&gt;&lt;span class="special"&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;.

  &lt;div id="version_1_60_0.new_libraries"&gt;
    &lt;h3&gt;&lt;span class="link"&gt;New Libraries&lt;/span&gt;&lt;/h3&gt;
    &lt;ul&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class="library"&gt;&lt;a href="http://www.boost.org/libs/vmd/"&gt;VMD&lt;/a&gt;:&lt;/span&gt;
  Variadic Macro Data library,
          from Edward Diener.
        &lt;/div&gt;
      &lt;/li&gt;
    &lt;/ul&gt;
  &lt;/div&gt;
  &lt;div id="version_1_60_0.updated_libraries"&gt;
    &lt;h3&gt;&lt;span class="link"&gt;Updated Libraries&lt;/span&gt;&lt;/h3&gt;
    &lt;ul&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class="library"&gt;&lt;a href="http://www.boost.org/libs/atomic/"&gt;Atomic&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Enforced proper alignment of &lt;code&gt;&lt;span class="identifier"&gt;atomic&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt; storage. This should fix
                possible issues on platforms that support atomic operations on data
                units larger than the native word size. This may also change binary
                layout of user's data structures that have &lt;code&gt;&lt;span class="identifier"&gt;atomic&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt; members.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed compilation for PowerPC with IBM XL C++ compiler. Corrected
                memory barriers in PowerPC assembler.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed compilation with MSVC-8 for ARM.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed compilation with gcc 4.4 for x86-64, when 128-bit atomic operations
                were used. (&lt;a href="https://svn.boost.org/trac/boost/ticket/10994"&gt;#10994&lt;/a&gt;)
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Optimized some gcc assembler blocks for x86/x86-64 to reduce the
                number of used registers. This may require binutils 2.10 or later.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;

                is defined &lt;a href="https://svn.boost.org/trac/boost/ticket/11669"&gt;#11669&lt;/a&gt;
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Suppress some of the warning reported in &lt;a href="https://svn.boost.org/trac/boost/ticket/11570"&gt;#11570&lt;/a&gt; and &lt;a href="https://svn.boost.org/trac/boost/ticket/4946"&gt;#4946&lt;/a&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Implemented generic codecvt facet and add general purpose utf8_codecvt
                facet
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added posix locale support for FreeBSD 10.0 and above
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed issues &lt;a href="https://svn.boost.org/trac/boost/ticket/10017"&gt;#10017&lt;/a&gt; (sun redefinition on SunOS), &lt;a href="https://svn.boost.org/trac/boost/ticket/11163"&gt;#11163&lt;/a&gt; (set_default_messages_domain
                incorrect behavior), &lt;a href="https://svn.boost.org/trac/boost/ticket/11673"&gt;#11673&lt;/a&gt; build issues

            &lt;li&gt;
              &lt;div&gt;
                Some warning cleanup

            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed tests for latest ICU versions
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added workaround for &lt;code&gt;&lt;span class="identifier"&gt;libc&lt;/span&gt;&lt;span class="special"&gt;++&lt;/span&gt;&lt;/code&gt; issues
              &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;
                Added new defines &lt;code&gt;&lt;span class="identifier"&gt;BOOST_LOCALE_ENABLE_CHAR16_T&lt;/span&gt;&lt;/code&gt;
                and &lt;code&gt;&lt;span class="identifier"&gt;BOOST_LOCALE_ENABLE_CHAR32_T&lt;/span&gt;&lt;/code&gt;
                to enable C++11 &lt;code&gt;&lt;span class="keyword"&gt;char16_t&lt;/span&gt;&lt;/code&gt;
                and &lt;code&gt;&lt;span class="keyword"&gt;char32_t&lt;/span&gt;&lt;/code&gt; instead
                of deprecated ones
              &lt;/div&gt;
            &lt;/li&gt;

            &lt;li&gt;
              &lt;div&gt;
                General changes:
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      On Windows, the configuration macro &lt;code&gt;&lt;span class="identifier"&gt;BOOST_LOG_USE_WINNT6_API&lt;/span&gt;&lt;/code&gt;
                      is no longer used by the library. The target Windows version
                      should be configured by defining macro &lt;code&gt;&lt;span class="identifier"&gt;BOOST_USE_WINAPI_VERSION&lt;/span&gt;&lt;/code&gt;.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Bug fixes:
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Fixed compilation for Android using Google NDK. (&lt;a href="https://svn.boost.org/trac/boost/ticket/11559"&gt;#11559&lt;/a&gt;)
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Fixed compilation of some logging statements, where the first
                      object to be put into stream is not directly supported by
                      &lt;code&gt;&lt;span class="identifier"&gt;formatting_ostream&lt;/span&gt;&lt;/code&gt;.
                      (&lt;a href="https://svn.boost.org/trac/boost/ticket/11549"&gt;#11549&lt;/a&gt;)
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added a workaround for Solaris Studio 12.4, which should fix
                      the compilation of &lt;code&gt;&lt;span class="identifier"&gt;formatting_ostream&lt;/span&gt;&lt;/code&gt;.
                      (&lt;a href="https://svn.boost.org/trac/boost/ticket/11545"&gt;#11545&lt;/a&gt;)
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Fixed compilation when native &lt;code&gt;&lt;span class="keyword"&gt;wchar_t&lt;/span&gt;&lt;/code&gt;
                      type is disabled. (&lt;a href="https://svn.boost.org/trac/boost/ticket/11541"&gt;#11541&lt;/a&gt;)
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Fixed exporting symbols from the &lt;code&gt;&lt;span class="identifier"&gt;boost_log_setup&lt;/span&gt;&lt;/code&gt;
                      library on POSIX-like systems.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Fixed compilation of character decorators.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added a workaround for incorrect file name generation in text
                      file sink backend, when the file name contains date/time placeholders.
                      (&lt;a href="https://svn.boost.org/trac/boost/ticket/11691"&gt;#11691&lt;/a&gt;)
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;

            &lt;li&gt;
              &lt;div&gt;
                Fixed bug &lt;a href="https://svn.boost.org/trac/boost/ticket/11615"&gt;Trac
                #11615: &lt;em&gt;"Boost.Move should use the qualified name
                for std::size_t in type_traits.hpp"&lt;/em&gt;&lt;/a&gt;,
              &lt;/div&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed an interoperability problem with &lt;a href="http://www.qt.io/"&gt;Qt&lt;/a&gt;
                due to the optional definition of a macro with name &lt;code&gt;&lt;span class="identifier"&gt;foreach&lt;/span&gt;&lt;/code&gt; in this framework.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Maintenance fixes.
              &lt;/div&gt;
            &lt;/li&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                New features:
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added functionality to throw an exception if too many ODE steps
                      are performed.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added possibility to limit maximal step size in adaptive methods.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                several Bug fixes, see https://github.com/headmyshoulder/odeint-v2/issues
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;

          &lt;span class="library"&gt;&lt;a href="http://www.boost.org/libs/optional/"&gt;Optional&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed the implementation of &lt;code&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;none&lt;/span&gt;&lt;/code&gt;
                again. Now it is a const object with internal linkage (as any other
                tag). This fixes &lt;a href="https://svn.boost.org/trac/boost/ticket/11203"&gt;#11203&lt;/a&gt;.
              &lt;/div&gt;

                    &lt;div&gt;

        This release of Boost will by default compile for Windows Vista/Windows Server
        2008, if the compiler supports a recent enough Windows SDK, and for Windows
        XP otherwise. Binaries compiled with default options may not run on the older
        Windows versions.
      &lt;/p&gt;
      &lt;p&gt;
        It is still possible to explicitly specify target Windows version by defining
        &lt;code&gt;&lt;span class="identifier"&gt;BOOST_USE_WINAPI_VERSION&lt;/span&gt;&lt;/code&gt;
        to a numeric version of Windows API. For example, building Boost for Windows
        XP can be done with the following command:
      &lt;/p&gt;
&lt;pre&gt;    b2 release define=BOOST_USE_WINAPI_VERSION=0x0501
&lt;/pre&gt;
      &lt;p&gt;
        The list of Windows API version numbers can be seen on &lt;a href="https://msdn.microsoft.com/en-us/library/6sehtctf.aspx"&gt;this&lt;/a&gt;
        page.
      &lt;/p&gt;
      &lt;p&gt;
        This change only concerns libraries that use the common Windows API abstraction
        layer. Currently, these libraries are: Boost.Chrono, Boost.Dll, Boost.Log,
        Boost.UUID. This will also affect all dependent libraries.
      &lt;/p&gt;
    &lt;/div&gt;
    &lt;div id="version_1_60_0.news.release_of_hana_postponed"&gt;

      &lt;p&gt;
        Due to time constraints, the release of &lt;a href="https://github.com/boostorg/hana"&gt;Hana&lt;/a&gt;
        will be postponed to a later release of Boost. This will also allow some
        known issues to be addressed properly before releasing the library officially
        as a part of Boost. More information can be found on the &lt;a href="http://article.gmane.org/gmane.comp.lib.boost.devel/263964"&gt;mailing
        list&lt;/a&gt;.

      &lt;p&gt;
        In order to provide superior support of uncommon toolsets and platforms,
        the release of Boost.DLL was postponed to a later release of Boost. This
        also allows to test better a recently added ability to copy construct and
        copy assign instances of &lt;code&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;dll&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;shared_library&lt;/span&gt;&lt;/code&gt; and provide examples on
        importing functions with non default calling conventions. Latest version
        and developer documentation of the library could be found at &lt;a href="https://github.com/boostorg/dll"&gt;GitHub

                    &lt;div&gt;
                      Buffer: use a more robust way to calculate the side of an intersection,
                      this fixes several errors in buffer generation
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Fix in selection of segment to which calculate from IP from,
                      in intersection of two segments. Now is selected the one close
                      to a segment-point point, or else the one on the shortest segment.
                      This avoids (rarely occuring) generation of tiny triangles
                      making output polygons invalid
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      In rescaling round instead of truncate to the integer grid
                      (this fix and the previous mentioned can have some impact on
                      output geometries)
                    &lt;/div&gt;

                    &lt;div&gt;
                      Fix potential infinite loop in detail::has_spikes (the loop
                      can happen if the points passed have NaN coordinates)
                    &lt;/div&gt;

                General changes:
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      On systems with &lt;a href=&quot;https://gcc.gnu.org/wiki/Visibility&quot;&gt;symbol
                      visibility&lt;/a&gt; support (e.g. Linux) the library is now
                      built with all internal symbols hidden.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      &lt;strong&gt;Breaking change:&lt;/strong&gt; The library
                      has been ported to Boost.TypeIndex for its underlying type
                      info management tool. This affected the following public interfaces:
                      &lt;ul&gt;
                        &lt;li&gt;
                          &lt;div&gt;
                            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;invalid_type&lt;/span&gt;&lt;/code&gt;
                            exceptions thrown by the library now have &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;typeindex&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;type_index&lt;/span&gt;&lt;/code&gt; attached
                            as the description of the offending type. The type was
                            previously identified by &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;type_info_wrapper&lt;/span&gt;&lt;/code&gt;.
                          &lt;/div&gt;
                        &lt;/li&gt;
                        &lt;li&gt;
                          &lt;div&gt;
                            Boost.Exception &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;type_info_info&lt;/span&gt;&lt;/code&gt;
                            error information now contains &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;typeindex&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;type_index&lt;/span&gt;&lt;/code&gt;
                            instead of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;type_info_wrapper&lt;/span&gt;&lt;/code&gt;.
                          &lt;/div&gt;
                        &lt;/li&gt;
                        &lt;li&gt;
                          &lt;div&gt;
                            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;attribute_value&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;get_type&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; now returns &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;typeindex&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;type_index&lt;/span&gt;&lt;/code&gt; instead
                            of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;type_info_wrapper&lt;/span&gt;&lt;/code&gt;.
                            User-defined attribute value implementations should be
                            similarly changed (the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;attribute_value&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;impl&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;get_type&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; virtual method now
                            also returns &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;typeindex&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;type_index&lt;/span&gt;&lt;/code&gt;).
                          &lt;/div&gt;
                        &lt;/li&gt;
                      &lt;/ul&gt;
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;type_info_wrapper&lt;/span&gt;&lt;/code&gt;
                      component has been deprecated and will be removed in future
                      releases. Boost.TypeIndex is recommended as a replacement.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Removed the previously deprecated headers: &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;log&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;utility&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;intrusive_ref_counter&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;/code&gt;,

              &lt;div&gt;
                &lt;strong&gt;Breaking change:&lt;/strong&gt; The new parser
                does not support comments or string concatenation in JSON files.
                These features were non-standard extensions of the old parser but
                their removal could break code which was relying on them.

          Boost.Python will fail to build if it is compiled against a version of
          python that is one of: 3.0.X, 3.1.X, 3.2.X, 3.3.X. Versions 2.X and 3.4+
          are not affected. This is fixed in &lt;a href="https://github.com/boostorg/python/commit/3e405b6fd5db5615bbef241763de070118222ca7"&gt;git&lt;/a&gt;.

              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added new macro &lt;code&gt;&lt;span class="identifier"&gt;BOOST_ASIO_DISABLE_CONNECTEX&lt;/span&gt;&lt;/code&gt;
                to allow use of &lt;code&gt;&lt;span class="identifier"&gt;ConnectEx&lt;/span&gt;&lt;/code&gt;
                to be explicitly disabled.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed a race condition in &lt;code&gt;&lt;span class="identifier"&gt;windows&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;object_handle&lt;/span&gt;&lt;/code&gt;
                when there are pending wait operations on destruction (&lt;a href="https://svn.boost.org/trac/boost/ticket/10624"&gt;#10624&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed IPv6 address parsing on FreeBSD, where a trailing scope ID
                would cause conversion to fail with &lt;code&gt;&lt;span class="identifier"&gt;EINVAL&lt;/span&gt;&lt;/code&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Worked around shared library visibility issues by ensuring Asio types
                use default visibility (&lt;a href="https://svn.boost.org/trac/boost/ticket/9465"&gt;#9465&lt;/a&gt;, &lt;a href="https://svn.boost.org/trac/boost/ticket/11070"&gt;#11070&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed the SSL wrapper to call the password callback when loading
                an in-memory key (&lt;a href="https://svn.boost.org/trac/boost/ticket/10828"&gt;#10828&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed false SSL error reports by ensuring that the SSL error queue
                is cleared prior to each operation.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed an &lt;code&gt;&lt;span class="identifier"&gt;ssl&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;stream&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt;
                bug that may result in spurious 'short read' errors.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Removed a redundant null pointer check in the SSL engine (&lt;a href="https://svn.boost.org/trac/boost/ticket/10088"&gt;#10088&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added options for disabling TLS v1.1 and v1.2 (&lt;a href="https://svn.boost.org/trac/boost/ticket/10690"&gt;#10690&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Removed use of deprecated OpenSSL function &lt;code&gt;&lt;span class="identifier"&gt;ERR_remove_state&lt;/span&gt;&lt;/code&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed detection of various C++11 features with Clang (&lt;a href="https://svn.boost.org/trac/boost/ticket/8835"&gt;#8835&lt;/a&gt;,
                &lt;a href="https://svn.boost.org/trac/boost/ticket/10884"&gt;#10884&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed detection of C++11 &lt;code&gt;&lt;span class="identifier"&gt;std&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;addressof&lt;/span&gt;&lt;/code&gt;
                with &lt;tt&gt;g++&lt;/tt&gt; (&lt;a href="https://svn.boost.org/trac/boost/ticket/10982"&gt;#10982&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed multicast test to treat certain &lt;code&gt;&lt;span class="identifier"&gt;join_group&lt;/span&gt;&lt;/code&gt;
                failures as non-fatal.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Decoupled Asio unit tests from Boost.Test (&lt;a href="https://svn.boost.org/trac/boost/ticket/11116"&gt;#11116&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed the tutorial to use &lt;code&gt;&lt;span class="identifier"&gt;std&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;endl&lt;/span&gt;&lt;/code&gt;
                to ensure output is flushed.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed an unsigned integer overflow reported by Clang's integer sanitizer.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added support for move-only return types when using a &lt;code&gt;&lt;span class="identifier"&gt;yield_context&lt;/span&gt;&lt;/code&gt; object with asynchronous
                operations.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed &lt;code&gt;&lt;span class="identifier"&gt;yield_context&lt;/span&gt;&lt;/code&gt;
                to allow reentrant calls to the completion handler from an initiating
                function.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Updated detection of Windows Runtime to work with latest Windows
                SDK.
              &lt;/div&gt;
            &lt;/li&gt;

                Massive dependency reorganization. Now &lt;em&gt;Boost.Container&lt;/em&gt;
                depends on very basic utilities like Boost.Core and &lt;em&gt;Boost.Intrusive&lt;/em&gt;.
                Preprocessed code size have decreased considerably and compilation
                times have improved.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added &lt;code&gt;&lt;span class="identifier"&gt;nth&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class="identifier"&gt;index_of&lt;/span&gt;&lt;/code&gt; functions to containers

            &lt;li&gt;
              &lt;div&gt;

                &lt;code&gt;&lt;span class="identifier"&gt;propagate_on_container_move_assignment&lt;/span&gt;&lt;/code&gt;
                and &lt;code&gt;&lt;span class="identifier"&gt;propagate_on_container_swap&lt;/span&gt;&lt;/code&gt;
                are no longer &lt;code&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;integral_constant&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="keyword"&gt;bool&lt;/span&gt;&lt;span class="special"&gt;,&lt;/span&gt; &lt;span class="keyword"&gt;true&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="keyword"&gt;false&lt;/span&gt;&lt;span class="special"&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt; types. The dependency reorganization
                needed to break with those classes to avoid MPL dependencies, and
                interoperability with &lt;code&gt;&lt;span class="identifier"&gt;std&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;integral_constant&lt;/span&gt;&lt;/code&gt;
                was not guaranteed. Code assumming &lt;code&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;true_type&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;false_type&lt;/span&gt;&lt;/code&gt;
                on this will not compile. As a workaround, use the guaranteed internal
                &lt;code&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;value&lt;/span&gt;&lt;/code&gt;
                constant: &lt;code&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;integral_constant&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="keyword"&gt;bool&lt;/span&gt;&lt;span class="special"&gt;,&lt;/span&gt; &lt;span class="identifier"&gt;scoped_allocator_adaptor&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="identifier"&gt;Allocator&lt;/span&gt;&lt;span class="special"&gt;&amp;gt;::&lt;/span&gt;&lt;span class="identifier"&gt;propagate_on_container_move_assignment&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;value&lt;/span&gt;&lt;span class="special"&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;.

                functions were added (thanks to Boris Rasin) &lt;a href="https://svn.boost.org/trac/boost/ticket/10780"&gt;#10780&lt;/a&gt;

              &lt;div&gt;
                Renamed variable v_type to var_type so it longer conflicts with an

            &lt;li&gt;
              &lt;div&gt;
                Minor breaking change: the default template parameter to indicate
                that it shouldn't use an allocator is now &lt;code&gt;&lt;span class="keyword"&gt;void&lt;/span&gt;&lt;/code&gt;,
                instead of &lt;code&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;none_t&lt;/span&gt;&lt;/code&gt;.

            &lt;li&gt;
              &lt;div&gt;
                New ADAPT_STRUCT, ADAPT_ADT, ADAPT_ASSOC_ that deduce the members

            &lt;li&gt;
              &lt;div&gt;
                Add mpl::clear implementation for Boost.Tuple and std::tuple.

            &lt;li&gt;

            &lt;li&gt;
              &lt;div&gt;
                Better constexpr and noexcept support.
              &lt;/div&gt;

            &lt;li&gt;

              &lt;div&gt;
                result_of::at&amp;lt;Seq, N&amp;gt;::type is now defined when sizeof of sequence

                    &lt;div&gt;
                      New algorithm num_segments, returning the number of segments

                    &lt;div&gt;
                      New overload for is_valid algorithm, that takes a string reference
                      as a second argument and fills it with a message related to
                      the validity or invalidity of the geometry

                    &lt;div&gt;
                      Disjoint and intersects support the following geometry combinations:
                      point/multipoint, multipoint/multipoint, multipoint/segment,

                      Buffer now supports flat-ends for linestrings with a bend close

                      Bug in rtree count() member function, the use of reference

                      not the same as value_type or indexable_type is passed. If
                      this happens, wrong result may be returned, in most cases 0.

                  &lt;li&gt;

                      if free space on the file system gets exhausted. The sink will
                      no longer create lots of empty files in attempt to recover.

              &lt;div&gt;
                Added two new special functions - trigamma and polygamma.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Large update to the Elliptic integral code to use Carlson's latest
                algorithms - these should be more stable, more accurate and slightly
                faster than before. Also added support for Carlson's RG integral.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added ellint_d, jacobi_zeta and heuman_lambda elliptic integrals.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed namespace scope constants so they are constexpr on conforming
                compilers, see &lt;a href="https://svn.boost.org/trac/boost/ticket/10901"&gt;#10901&lt;/a&gt;.

            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed various cases of spurious under/overflow in the incomplete
                beta and gamma functions, plus the elliptic integrals, with thanks
                to Rocco Romeo.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fix 3-arg legendre_p and legendre_q functions to not call the policy
                based overload if the final argument is not actually a policy.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Cleaned up some dead code in the incomplete beta function, see &lt;a href="https://svn.boost.org/trac/boost/ticket/10985"&gt;#10985&lt;/a&gt;.
              &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;

              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Switched documentation to use SVG rather than PNG graphs and equations
                - browsers seem to have finally caught up!
              &lt;/div&gt;

&lt;pre&gt;&lt;span class="keyword"&gt;typedef&lt;/span&gt; &lt;span class="identifier"&gt;multi_index_container&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;

  &lt;span class="identifier"&gt;indexed_by&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;
    &lt;span class="identifier"&gt;ordered_unique&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="identifier"&gt;identity&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="identifier"&gt;std&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;string&lt;/span&gt;&lt;span class="special"&gt;&amp;gt;&lt;/span&gt; &lt;span class="special"&gt;&amp;gt;&lt;/span&gt;
  &lt;span class="special"&gt;&amp;gt;&lt;/span&gt;
&lt;span class="special"&gt;&amp;gt;&lt;/span&gt; &lt;span class="identifier"&gt;multi_t&lt;/span&gt;&lt;span class="special"&gt;;&lt;/span&gt;
&lt;span class="special"&gt;...&lt;/span&gt;
&lt;span class="identifier"&gt;multi_t&lt;/span&gt; &lt;span class="identifier"&gt;m&lt;/span&gt;&lt;span class="special"&gt;=...;&lt;/span&gt;
&lt;span class="identifier"&gt;m&lt;/span&gt;&lt;span class="special"&gt;.&lt;/span&gt;&lt;span class="identifier"&gt;find&lt;/span&gt;&lt;span class="special"&gt;(&lt;/span&gt;&lt;span class="string"&gt;"boost"&lt;/span&gt;&lt;span class="special"&gt;);&lt;/span&gt; &lt;span class="comment"&gt;// passed a const char*, not a std::string    &lt;/span&gt;
&lt;/pre&gt;
              &lt;div&gt;
                In previous versions of the library, the &lt;code&gt;&lt;span class="identifier"&gt;find&lt;/span&gt;&lt;/code&gt;
                operation generates several temporary &lt;code&gt;&lt;span class="identifier"&gt;std&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;string&lt;/span&gt;&lt;/code&gt;s
                (one every time an internal comparison is made). In sufficiently
                advanced compilers, this is now avoided so that only one temporary
                is created.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;

                Maintenance fixes.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed &lt;code&gt;&lt;span class="identifier"&gt;frexp&lt;/span&gt;&lt;/code&gt; to
                always be non-expression template generating, see: &lt;a href="https://svn.boost.org/trac/boost/ticket/10993"&gt;10993&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Improved support of cpp_dec_float on Cygwin and other platforms with
                missing long double support, see &lt;a href="https://svn.boost.org/trac/boost/ticket/10924"&gt;10924&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Improved noexcept support and added some more tests, see &lt;a href="https://svn.boost.org/trac/boost/ticket/10990"&gt;10990&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Various workarounds applied for Intel-15.0 and Solaris-12.4 compilers.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class="library"&gt;&lt;a href="http://www.boost.org/libs/optional/"&gt;Optional&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Improved documentation; documented IO operations and header files.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                &lt;em&gt;Fixed Bugs:&lt;/em&gt;
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      &lt;code&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;none_t&lt;/span&gt;&lt;/code&gt; is no longer convertible
                      from literal 0. This avoids a bug where &lt;code&gt;&lt;span class="identifier"&gt;optional&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="identifier"&gt;rational&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="keyword"&gt;int&lt;/span&gt;&lt;span class="special"&gt;&amp;gt;&amp;gt;&lt;/span&gt; &lt;span class="identifier"&gt;oi&lt;/span&gt;
                      &lt;span class="special"&gt;=&lt;/span&gt; &lt;span class="number"&gt;0&lt;/span&gt;&lt;span class="special"&gt;;&lt;/span&gt;&lt;/code&gt; would initialize an optional
                      object with no contained value.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added a way to manually disable move semantics: just define
                      macro &lt;code&gt;&lt;span class="identifier"&gt;BOOST_OPTIONAL_CONFIG_NO_RVALUE_REFERENCES&lt;/span&gt;&lt;/code&gt;.
                      This can be used to work around &lt;a href="http://svn.boost.org/trac/boost/ticket/10399"&gt;#10399&lt;/a&gt;.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      &lt;a href="http://svn.boost.org/trac/boost/ticket/10825"&gt;#10825&lt;/a&gt;
                      Improved the trick that prevents streaming out &lt;code&gt;&lt;span class="identifier"&gt;optional&lt;/span&gt;&lt;/code&gt; without header
                      &lt;code&gt;&lt;span class="identifier"&gt;optional_io&lt;/span&gt;&lt;span class="special"&gt;.&lt;/span&gt;&lt;span class="identifier"&gt;hpp&lt;/span&gt;&lt;/code&gt;
                      by using safe-bool idiom.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      &lt;a href="http://svn.boost.org/trac/boost/ticket/11087"&gt;#11087&lt;/a&gt;
                      It is no longer possible to assign &lt;code&gt;&lt;span class="identifier"&gt;optional&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="identifier"&gt;U&lt;/span&gt;&lt;span class="special"&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt; to &lt;code&gt;&lt;span class="identifier"&gt;optional&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="identifier"&gt;T&lt;/span&gt;&lt;span class="special"&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt; when &lt;code&gt;&lt;span class="identifier"&gt;U&lt;/span&gt;&lt;/code&gt;
                      is not assignable or convertible to &lt;code&gt;&lt;span class="identifier"&gt;T&lt;/span&gt;&lt;/code&gt;.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      &lt;a href="http://svn.boost.org/trac/boost/ticket/10839"&gt;#10839&lt;/a&gt;
                      Value accessors now work correctly on rvalues of &lt;code&gt;&lt;span class="identifier"&gt;optional&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="identifier"&gt;T&lt;/span&gt;&lt;span class="special"&gt;&amp;amp;&amp;gt;&lt;/span&gt;&lt;/code&gt;.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;

                    &lt;div&gt;
                      Phoenix now has a &lt;em&gt;lazy list&lt;/em&gt; implementation
                      as an optional extension.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;

                    &lt;div&gt;
                      A new example &lt;em&gt;bind_goose&lt;/em&gt; shows the compatibility
                      between &lt;em&gt;boost bind&lt;/em&gt; and &lt;em&gt;boost

                &lt;em&gt;Fixed Bugs:&lt;/em&gt;

                      Fixes for a number of cases failing with &lt;em&gt;bind&lt;/em&gt;,

            &lt;li&gt;
              &lt;div&gt;
                Added Visual Studio 2015 detection.

            &lt;li&gt;
              &lt;div&gt;
                Added detection of Haiku OS.

            &lt;li&gt;

            &lt;li&gt;
              &lt;div&gt;

                program and BBv2 integration for build configuration checks.
              &lt;/div&gt;

                &lt;em&gt;Fixed Bugs:&lt;/em&gt;
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      &lt;a href="http://svn.boost.org/trac/boost/ticket/6787"&gt;#6787&lt;/a&gt;
                      boost::thread::sleep() hangs if system time is rolled back
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      &lt;a href="http://svn.boost.org/trac/boost/ticket/10734"&gt;#10734&lt;/a&gt;
                      Submit method work differently on different executors, some
                      throw exception and some silently ignore error (thread_executor
                      and inline_executor)
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      &lt;a href="http://svn.boost.org/trac/boost/ticket/10736"&gt;#10736&lt;/a&gt;
                      Task exceptions silently ignored. I think std::terminate solution
                      from N3785 and std::thread is better choice and more consistent.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;

                      &lt;a href="http://svn.boost.org/trac/boost/ticket/10737"&gt;#10737&lt;/a&gt;
                      In serial_executor we have infinite wait if task throw exception.
                    &lt;/div&gt;
                  &lt;/li&gt;

                RTTI is not required any more (&lt;a href=&quot;http://www.boost.org/libs/type_index&quot;&gt;TypeIndex&lt;/a&gt;
                library is used for RTTI emulation)

            &lt;li&gt;
              &lt;div&gt;
                Fixed the &lt;tt&gt;kqueue&lt;/tt&gt; reactor so that it works on FreeBSD
                (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/10606&quot;&gt;#10606&lt;/a&gt;).

            &lt;li&gt;
              &lt;div&gt;
                Fixed an issue in the &lt;tt&gt;kqueue&lt;/tt&gt; reactor which resulted

              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed &lt;tt&gt;kqueue&lt;/tt&gt; reactor support for read-only file
                descriptors (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/10367&quot;&gt;#10367&lt;/a&gt;).

            &lt;li&gt;
              &lt;div&gt;
                Fixed a compile error when using the &lt;tt&gt;/dev/poll&lt;/tt&gt;
                reactor (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/10350&quot;&gt;#10350&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/10572&quot;&gt;#10572&lt;/a&gt;).

            &lt;li&gt;
              &lt;div&gt;
                Changed the Windows backend to use &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;WSASocketW&lt;/span&gt;&lt;/code&gt;,
                as &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;WSASocketA&lt;/span&gt;&lt;/code&gt; has
                been deprecated (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/10534&quot;&gt;#10534&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed some warnings reported by Visual C++ 2013 (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/10376&quot;&gt;#10376&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed integer type used in the WinRT version of the byte-order conversion
                functions (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/10539&quot;&gt;#10539&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed documentation to indicate that &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;use_future&lt;/span&gt;&lt;/code&gt;
                and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;spawn&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
                are not made available when including the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;asio&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;/code&gt;
                convenience header (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/10567&quot;&gt;#10567&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;

                as deprecated. Use &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;asio&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;io_service&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;strand&lt;/span&gt;&lt;/code&gt;
                instead.
              &lt;/div&gt;
            &lt;/li&gt;

            &lt;li&gt;
              &lt;div&gt;
                Fixed some warnings and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;move_if_noexcept&lt;/span&gt;&lt;/code&gt;

            &lt;li&gt;
              &lt;div&gt;
                Most components of the library were moved into the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;iterators&lt;/span&gt;&lt;/code&gt; namespace. For backward
                compatibility the components are also accessible in the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;/code&gt; namespace.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Iterator operators are now conditionally defined based on the iterator
                category.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Some of the internal components of the library were made public (&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;minimum_category&lt;/span&gt;&lt;/code&gt;, for example).
              &lt;/div&gt;
            &lt;/li&gt;

                Some internal changes, library now consist of multiple headers instead

            &lt;li&gt;
              &lt;div&gt;
                Added Hyperexponential Distribution.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fix some spurious overflows in the incomplete gamma functions (with
                thanks to Rocco Romeo).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fix bug in derivative of incomplete beta when a = b = 0.5 - this
                also effects several non-central distributions, see issue 10480.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed some corner cases in function round.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Don't support 80-bit floats in cstdfloat.hpp if standard library
                support is broken.
              &lt;/div&gt;
            &lt;/li&gt;

      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;unique_ptr&lt;/span&gt;&lt;/code&gt; smart
          pointer. Thanks to Howard Hinnant for his excellent unique_ptr emulation
          code and testsuite.
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;move_if_noexcept&lt;/span&gt;&lt;/code&gt;
          utility. Thanks to Antony Polukhin for the implementation.

            &lt;li&gt;
              &lt;div&gt;
                Changed rational to float conversions to exactly round to nearest.

              &lt;/div&gt;
            &lt;/li&gt;

                the first argument to select the correct implementation.

              &lt;div&gt;
                added two new types: matrix_row and matrix_column facades . With
                them, it is possible to access to the matrices as an array of rows
                and an array of columns, respectively.
              &lt;/div&gt;

            &lt;li&gt;

                added fixed_vector/fixed_matrix classes to represent small - fixed

            &lt;li&gt;

            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                the interface of matrices and vectors has been extended with cbegin,
                cend, crbegin and crend member functions, as defined in c++11.

            &lt;/li&gt;
            &lt;li&gt;

            &lt;li&gt;

                performed a very large overhaul with respect to warnings and errors
                on various compilers. Apart for some hard to resolve warnings and
                older compiler incompatibilities, compilations with uBlas will be
                much cleaner now.

    &lt;p&gt;
      Boost version control has migrated to a system using git submodules. This shouldn't
      make too much of a difference to users, although the directory structure is
      now a bit different.
    &lt;/p&gt;
    &lt;p&gt;
      Parts of some libraries have been moved into different modules, and several
      new modules have been extracted from existing code. All header paths should
      remain the same. The new modules are:
    &lt;/p&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed rvalue references related issues (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9215&quot;&gt;#9215&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9462&quot;&gt;#9462&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Dropped support of antique compilers.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;
                Fixed &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;asio&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;spawn&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
                to work correctly with new Boost.Coroutine interface (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9442&quot;&gt;#9442&lt;/a&gt;,
                &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9928&quot;&gt;#9928&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Ensured that incomplete &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;asio&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;spawn&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; coroutines are correctly unwound
                when cleaned up by the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;io_service&lt;/span&gt;&lt;/code&gt;
                destructor (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9731&quot;&gt;#9731&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed delegation of continuation hook for handlers produced by &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;io_service&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;wrap&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
                and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;strand&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;wrap&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
                (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9741&quot;&gt;#9741&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed the Windows I/O completion port backend to use &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ConnectEx&lt;/span&gt;&lt;/code&gt;, if available, for connection-oriented
                IP sockets.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;io_service&lt;/span&gt;&lt;/code&gt;
                backend for non-Windows (and non-IOCP Windows) platforms to use a
                single condition variable per &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;io_service&lt;/span&gt;&lt;/code&gt;
                instance. This addresses a potential race condition when &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;run_one&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
                is used from multiple threads.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Prevented integer overflow when computing timeouts based on some
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;chrono&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;std&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;chrono&lt;/span&gt;&lt;/code&gt;
                clocks (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9662&quot;&gt;#9662&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9778&quot;&gt;#9778&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Made further changes to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;EV_CLEAR&lt;/span&gt;&lt;/code&gt;
                handling in the kqueue backend, to address other cases where the
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;close&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
                system call may hang on Mac OS X.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed infinite recursion in implementation of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;resolver_query_base&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;flags&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;keyword&quot;&gt;operator&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;~&lt;/span&gt;&lt;/code&gt; (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9548&quot;&gt;#9548&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Made the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;select&lt;/span&gt;&lt;/code&gt; reactor
                more efficient on Windows for large numbers of sockets (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9528&quot;&gt;#9528&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed a Windows-specific type-aliasing issue reported by &lt;tt&gt;gcc&lt;/tt&gt;
                (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9550&quot;&gt;#9550&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Prevented execution of compile-time-only buffer test to avoid triggering
                an address sanitiser warning (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8295&quot;&gt;#8295&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Disabled the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;GetQueuedCompletionStatus&lt;/span&gt;&lt;/code&gt;
                timeout workaround on recent versions of Windows.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added support for string-based scope IDs when using link-local multicast
                addresses.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed IPv6 multicast group join to use the address's scope ID as
                the interface, if an interface is not explicitly specified.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed multicast test failure on Mac OS X and the BSDs by using a
                link-local multicast address.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Worked around a &lt;tt&gt;gcc&lt;/tt&gt; problem to do with anonymous
                enums (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/10042&quot;&gt;#10042&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Reverted the Windows &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;HANDLE&lt;/span&gt;&lt;/code&gt;
                backend change to ignore &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ERROR_MORE_DATA&lt;/span&gt;&lt;/code&gt;.
                Instead, the error will be propagated as with any other (i.e. in
                an &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;error_code&lt;/span&gt;&lt;/code&gt; or
                thrown as a &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;system_error&lt;/span&gt;&lt;/code&gt;),
                and the number of bytes transferred will be returned. For code that
                needs to handle partial messages, the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;error_code&lt;/span&gt;&lt;/code&gt;
                overload should be used (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/10034&quot;&gt;#10034&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed an off-by-one error in the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;signal_set&lt;/span&gt;&lt;/code&gt;
                implementation's signal number check (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9324&quot;&gt;#9324&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed to use SSE2 intrinsics rather than inline assembly, to allow
                the Cray compiler to work.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Stopped using certain Winsock functions that are marked as deprecated
                in the latest Visual C++ and Windows SDK.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added a workaround for building the unit tests with &lt;tt&gt;gcc&lt;/tt&gt;
                on AIX.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Various minor documentation improvements (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8295&quot;&gt;#8295&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9605&quot;&gt;#9605&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9771&quot;&gt;#9771&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/assign/&quot;&gt;Assign&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Resolve some C++11 ambiguities (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3073&quot;&gt;#3073&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/atomic/&quot;&gt;Atomic&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                The library has been redesigned. Besides internal refactoring, various
                bugs were fixed, including incorrect values of feature test macros
                and integer overflow handling.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed values of the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;memory_order&lt;/span&gt;&lt;/code&gt;
                enumeration. The concrete values are not part of the interface, but
                this change may potentially break ABI, if the enum is used in user's
                interfaces.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Implemented support for 128-bit atomic operations on Windows x64
                with MSVC. The library assumes presence of the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;cmpxchg16b&lt;/span&gt;&lt;/code&gt;
                instruction in the target CPUs. Some early AMD CPUs don't support
                this instruction. To target those define the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_ATOMIC_NO_CMPXCHG16B&lt;/span&gt;&lt;/code&gt;
                macro.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Implemented experimental support for Windows ARM target with MSVC.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Implemented experimental support for DEC Alpha target with GCC.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Improved support for ARMv6 and later with GCC. Implemented all atomic
                operations as assembler blocks instead of CAS-based loops. 64-bit
                operations are supported with ARMv7.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Implemented optional support for the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_ATOMIC_FLAG_INIT&lt;/span&gt;&lt;/code&gt;
                macro and static initialization of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;atomic_flag&lt;/span&gt;&lt;/code&gt;.
                (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8158&quot;&gt;#8158&lt;/a&gt;)
              &lt;/div&gt;
            &lt;/li&gt;

                  &lt;li&gt;
                    &lt;div&gt;
                      intersects(polygon) could return a self-intersection-point
                      for its closing point, fixed
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      equals() could return invalid results for non-simple linear
                      geometries according to the OGC standard, fixed
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      touches() didn't work properly for CCW areal geomtries, fixed
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      rtree nearest queries returned wrong elements for non-cartesian
                      coordinate systems, fixed
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      rtree crashed in some cases when used with Interprocess allocator,
                      fixed
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;

            &lt;li&gt;
              &lt;div&gt;
                Removed some Visual C++ 6 workarounds.

                Ongoing work on improving &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;hash_combine&lt;/span&gt;&lt;/code&gt;,
                this changes the previously documented algorithm for the function.

                &lt;strong&gt;ABI breaking&lt;/strong&gt;: &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9221&quot;&gt;#9221&lt;/a&gt;
                showed that &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_INTERPROCESS_MSG_QUEUE_CIRCULAR_INDEX&lt;/span&gt;&lt;/code&gt;
                option of message queue, was completely broken so an ABI break was
                necessary to have a working implementation.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Simplified, refactored and unified (timed_)lock code based on try_lock().
                There were several bugs when handling timeout expirations.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed the implementation of condition variables' destructors to
                allow POSIX semantics (the condition variable can be destroyed after
                all waiting threads have been woken up)..
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_INTERPROCESS_SHARED_DIR_PATH&lt;/span&gt;&lt;/code&gt;
                option to define the shared directory used to place shared memory
                objects when implemented as memory mapped files.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added support for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_USE_WINDOWS_H&lt;/span&gt;&lt;/code&gt;.
                When this macro is defined Interprocess does not declare used Windows
                API function and types, includes all needed windows SDK headers and
                uses types and functions declared by the Windows SDK.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;get_size&lt;/span&gt;&lt;/code&gt; to
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;windows_shared_memory&lt;/span&gt;&lt;/code&gt;.
              &lt;/div&gt;
            &lt;/li&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Improved Doxygen generated reference and updated and fixed forward-declaration
                header.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                &lt;strong&gt;ABI breaking&lt;/strong&gt;: Fixed ABI regression
                introduced in Boost 1.55 version, mainly noticeable on MSVC compilers.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                &lt;strong&gt;Source breaking&lt;/strong&gt;: Removed previously
                deprecated &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;xxx_dont_splay&lt;/span&gt;&lt;/code&gt;
                functions from splay containers, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;splay_set_base_hook&lt;/span&gt;&lt;/code&gt;
                and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;splay_set_member_hook&lt;/span&gt;&lt;/code&gt;from
                splay containers and &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;bool&lt;/span&gt;
                &lt;span class=&quot;identifier&quot;&gt;splay&lt;/span&gt; &lt;span class=&quot;special&quot;&gt;=&lt;/span&gt;
                &lt;span class=&quot;keyword&quot;&gt;true&lt;/span&gt;&lt;/code&gt; extra parameter in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;splaytree_algorithms&lt;/span&gt;&lt;/code&gt; functions.
              &lt;/div&gt;

            &lt;li&gt;

            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Deleted workarounds for old SUN_CC compilers, those are now unsupported
                as modern SunPro compilers are standard-corforming enough.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;

            &lt;li&gt;
              &lt;div&gt;
                Added the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;try_lexical_convert&lt;/span&gt;&lt;/code&gt;
                function, that retuns &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;false&lt;/span&gt;&lt;/code&gt;
                in case of failed conversion and does not require output parameter

            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed conversion of string values with leading zeroes to &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;bool&lt;/span&gt;&lt;/code&gt; (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9659&quot;&gt;#9659&lt;/a&gt;).

            &lt;li&gt;
              &lt;div&gt;
                Code was changed to produce a smaller binaries and simplify compiler's

              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Boost.LexicalCast library was separated from the Boost.Conversion
                library.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed some warnings (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8991&quot;&gt;#8991&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;

        &lt;div&gt;
          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/log/index.html&quot;&gt;Log&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                General changes:
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      For Windows targets, the library now compiles for Windows XP
                      by default.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added indexing operators with &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;attribute_name&lt;/span&gt;&lt;/code&gt;
                      arguments to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;record&lt;/span&gt;&lt;/code&gt;
                      and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;record_view&lt;/span&gt;&lt;/code&gt;.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added operators for non-const object output to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;basic_formatting_ostream&lt;/span&gt;&lt;/code&gt;.
                      (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9389&quot;&gt;#9389&lt;/a&gt;)
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added support for putting function names and source file names
                      of named scopes into the formatted strings. (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9263&quot;&gt;#9263&lt;/a&gt;)
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added support for incomplete and empty markers to the named
                      scope formatter. (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9123&quot;&gt;#9123&lt;/a&gt;)
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      The default presentation for incomplete named scope lists has
                      changed: trailing scope delimiter is omitted.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added a support header for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;std&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;regex&lt;/span&gt;&lt;/code&gt;.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      By default Boost.Log uses Boost.Regex internally as the regular
                      expressions backend. The backend can be changed by defining
                      configuration macros.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Bug fixes:
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Fixed &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;dump&lt;/span&gt;&lt;/code&gt;
                      manipulator output on AVX2-enabled CPUs (e.g. Intel Haswell).
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Fixed compilation of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;get_attribute&lt;/span&gt;&lt;/code&gt;
                      method of loggers.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Fixed a possible race in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;locked_backend&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; function implementation of
                      synchronous and asynchronous sink frontends.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Fixed a possible infinite block of the logging threads in the
                      asynchronous sink enqueue methods when &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;block_on_overflow&lt;/span&gt;&lt;/code&gt;
                      strategy was used.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                See &lt;a href=&quot;http://www.boost.org/libs/log/doc/html/log/changelog.html&quot;&gt;changelog&lt;/a&gt;
                for more details.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/math/index.html&quot;&gt;Math&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                &lt;strong&gt;Breaking change&lt;/strong&gt;: moved a number
                of non-core headers that are predominantly used for internal maintenance
                into &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;libs&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;math&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;include_private&lt;/span&gt;&lt;/code&gt;. The headers effected
                are &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;math&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;tools&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;test_data&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;/code&gt;, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;math&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;tools&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;remez&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;/code&gt;,
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;math&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;constants&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;generate&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;/code&gt;, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;math&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;tools&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;solve&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;/code&gt;,
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;math&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;tools&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;test&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;/code&gt;. You can continue to use these
                headers by adding &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;libs&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;math&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;include_private&lt;/span&gt;&lt;/code&gt;
                to your compiler's include path.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                &lt;strong&gt;Breaking change&lt;/strong&gt;: A number of distributions
                and special functions were returning the maximum finite value rather
                than raising an overflow_error, this has now been fixed, which means
                these functions now behave as documented. However, since the default
                behavior on raising an overflow_error is to throw a &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;std&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;overflow_error&lt;/span&gt;&lt;/code&gt; exception, applications
                which have come to reply rely on these functions not throwing may
                experience exceptions where they did not before. The special functions
                involved are gamma_p_inva, gamma_q_inva, ibeta_inva, ibetac_inva,
                ibeta_invb, ibetac_invb, gamma_p_inv, gamma_q_inv. The distributions
                involved are pareto_distrib, beta_distrib, geometric_distrib, negative_binomial_distrib,
                binomial_distrib, chi_squared_distrib, gamma_distrib, inverse_chi_squared_distrib,
                inverse_gamma_distrib. See &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/10111&quot;&gt;#10111&lt;/a&gt;.

            &lt;li&gt;
              &lt;div&gt;
                Fix compilation failures on Mac OS.
              &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;
                Added bernoulli_numbers, changed arbitrary precision tgamma/lgamma
                to use Sterling's approximation (from Nikhar Agrawal).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added first derivatives of the Bessel functions: cyl_bessel_j_prime,
                cyl_neumann_prime, cyl_bessel_i_prime, cyl_bessel_k_prime, sph_bessel_prime
                and sph_neumann_prime (from Anton Bikineev).

            &lt;li&gt;
              &lt;div&gt;
                Fixed buggy Student's t example code, along with docs for testing
                sample means for equivalence.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Documented &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;max_iter&lt;/span&gt;&lt;/code&gt;

            &lt;li&gt;
              &lt;div&gt;
                Add option to explicitly enable/disable use of __float128 in constants

              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Cleaned up handling of negative values in Bessel I0 and I1 code (removed
                dead code), see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9512&quot;&gt;#9512&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed handling of very small values passed to tgamma and lgamma so
                they don't generate spurious overflows (thanks to Rocco Romeo).
              &lt;/div&gt;

            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed several corner cases in rising_factorial, falling_factorial
                and tgamma_delta_ratio with thanks to Rocco Romeo.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Removed constant &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;pow23_four_minus_pi&lt;/span&gt;
                &lt;/code&gt; whose value did not match the name (and was unused by Boost.Math),

            &lt;li&gt;

                member function of hashed indices used to have poor performance under
                low load conditions due to the requirement that an iterator to the
                next element must be returned (see ticket &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4264&quot;&gt;#4264&lt;/a&gt;). In accordance
                with the resolution of &lt;a href=&quot;http://lwg.github.io/issues/lwg-closed.html#579&quot;&gt;LWG
                issue #579&lt;/a&gt;, this problem has been fixed while maintaining
                the interface of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;erase&lt;/span&gt;&lt;/code&gt;,
                at the expense of using one more word of memory per element. In fact,
                C++ complexity requirements on unordered associative containers have
                been improved for hashed indices so that
              &lt;/div&gt;
              &lt;ul&gt;
                &lt;li&gt;
                  &lt;div&gt;
                    deletion of a given element is unconditionally constant-time,
                  &lt;/div&gt;
                &lt;/li&gt;
                &lt;li&gt;
                  &lt;div&gt;
                    worst-case performance is not &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;O&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;n&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)&lt;/span&gt;&lt;/code&gt; but &lt;code&gt;O(n&lt;sub&gt;dist&lt;/sub&gt;)&lt;/code&gt;, where &lt;code&gt;n&lt;sub&gt;dist&lt;/sub&gt;&lt;/code&gt; is the number of
                    non-equivalent elements in the index.
                  &lt;/div&gt;
                &lt;/li&gt;
              &lt;/ul&gt;
              &lt;div&gt;
                Due to the fact that hashed indices rely on a new data structure,
                the internal representation of their iterators and local iterators
                have changed, which affects serialization: their corresponding serialization
                &lt;a href=&quot;http://www.boost.org/libs/serialization/doc/tutorial.html#versioning&quot;&gt;class
                version&lt;/a&gt; has been bumped from 0 to 1. Old archives involving
                hashed index (local) iterators can be loaded by Boost 1.56 version
                of Boost.MultiIndex, but not the other way around.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Hashed indices now provide &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;reserve&lt;/span&gt;&lt;/code&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Hashed indices can now be checked for equality and inequality following
                the (suitably adapted) C++ standard specification in &lt;strong&gt;[unord.req]&lt;/strong&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                The public interface of Boost.MultiIndex provide &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;noexcept&lt;/span&gt;&lt;/code&gt;
                specifications where appropriate (for compliant compilers).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Improved performance of failed insertions into a &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;multi_index_container&lt;/span&gt;&lt;/code&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Much internal code aimed at supporting MSVC++ 7.0 and prior has been
                removed. Compilation times without this legacy code might be slightly
                faster.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed a bug with insertion via iterators dereferencing to rvalues
                (ticket &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9665&quot;&gt;#9665&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Made Boost.MultiIndex compatible with &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_BIND_NO_PLACEHOLDERS&lt;/span&gt;&lt;/code&gt;
                (ticket &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9798&quot;&gt;#9798&lt;/a&gt;).

              &lt;div&gt;
                Change floating point to rational conversions to be implicit, see
                &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/10082&quot;&gt;10082&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fix definition of checked_cpp_rational typedef.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fix bug in assignment from string in cpp_int, see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9936&quot;&gt;9936&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added new cpp_bin_float backend for binary floating point.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fix bug in assignment from string in cpp_int, see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9936&quot;&gt;9936&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added MSVC-specific #include for compiler intrinsics, see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9336&quot;&gt;9336&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed various typos in docs, see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9432&quot;&gt;9432&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed gmp_rational to allow move-copy from an already copied-from
                object, see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9497&quot;&gt;9497&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added list of values for numeric_limits.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/numeric/odeint/&quot;&gt;Odeint&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added algebra and operations dispatcher for automatic detection of
                appropriate algebras and operations.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added support for Eigen, Boost.Multiarray, Boost.Mpi, Boost.Compute,
                Blaze, and NT2.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed algebra interface to use algebra.norm_inf function.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added iterators for iterating through the solution of the ODEs, hence
                an alternative to the integrate functions.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added the Velocity-Verlet method.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Minor bug fixes.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/optional/&quot;&gt;Optional&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added support for rvalue references. Now &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;optional&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;T&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt; works with moveable but non-copyable
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;T&lt;/span&gt;&lt;/code&gt;'s.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Improved &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;swap&lt;/span&gt;&lt;/code&gt; (now
                uses move operations).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added function &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;emplace&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;. This is the last of the requests
                from &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1841&quot;&gt;#1841&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;optional&lt;/span&gt;&lt;/code&gt; is moveable,
                including conditional &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;noexcept&lt;/span&gt;&lt;/code&gt;
                specifications, which make it &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;move_if_noexcept&lt;/span&gt;&lt;/code&gt;-friendly.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Using explicit operator bool() on platforms that support it (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4227&quot;&gt;#4227&lt;/a&gt;)
                (breaking change).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Forward declaration of &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;operator&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;lt;(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;ostream&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;amp;,&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;optional&lt;/span&gt;
                &lt;span class=&quot;keyword&quot;&gt;const&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;amp;)&lt;/span&gt;&lt;/code&gt;
                to prevent inadvertent incorrect serialization of optional objects.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Removed depprecated function &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;reset&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; from examples (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9005&quot;&gt;#9005&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Equality comparison with &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;none&lt;/span&gt;&lt;/code&gt;
                does not require that &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;T&lt;/span&gt;&lt;/code&gt;
                be EqualityComparable.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Optional rvalue references are explicitly disallowed.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Binding temporaries to optional references is explicitly disallowed
                (breaking change).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                More ways to access the contained value, functions &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;value&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;,
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;value_or&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;,
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;value_or_eval&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Updated and reorganized documentation, added tutorial and quick guide
                sections.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;

            &lt;li&gt;
              &lt;div&gt;
                Addition of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_PLAT_&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;*&lt;/span&gt;&lt;/code&gt; platform definitions for MinGW and
                Windows platform variants.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Detection of ARM architecture for Windows compilers to target mobile
                devices of Windows 8.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Improved ARM detection for 64 bit ARM.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added detection of iOS as an operating system.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Improved detection of endianess on some platforms.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Addition of exclusive plus emulated definitions for platform and
                compiler detection.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                When using variadic macros tuple functionality was added to match
                all the array functionality.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;

              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Option names with dashes are no longer truncated in error messages

                to match existing documentation, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;basic_regex&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;subexpression&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;n&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)&lt;/span&gt;&lt;/code&gt; changed to match, see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9227&quot;&gt;#9227&lt;/a&gt;
              &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;
                Fixed issue &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8903&quot;&gt;#8903&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed documentation typos from &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9283&quot;&gt;#9283&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed bug in collation code that failed if the locale generated collation
                strings with embedded nul's, see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9451&quot;&gt;#9451&lt;/a&gt;.

            &lt;li&gt;
              &lt;div&gt;
                Apply patch for unusual thread usage (no statically initiallized
                mutexes), see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9461&quot;&gt;#9461&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added better checks for invalid UTF-8 sequences, see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9473&quot;&gt;#9473&lt;/a&gt;.

                is an alias for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;null_deleter&lt;/span&gt;&lt;/code&gt;,
                it will be removed in future releases.

            &lt;li&gt;
              &lt;div&gt;
                Implemented SSE-optimized versions of some functions of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;uuid&lt;/span&gt;&lt;/code&gt;, including comparison operators
                and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;swap&lt;/span&gt;&lt;/code&gt;. The support
                for different versions of SSE is automatically detected at compile
                time for most compilers, but can also be explicitly enabled or disabled
                with &lt;a href=&quot;http://www.boost.org/libs/uuid/uuid.html#Configuration&quot;&gt;configuration
                macros&lt;/a&gt;. (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8509&quot;&gt;#8509&lt;/a&gt;)

            &lt;li&gt;
              &lt;div&gt;
                Silenced some compiler warnings. (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8495&quot;&gt;#8495&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8697&quot;&gt;#8697&lt;/a&gt;)
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;

              &lt;div&gt;
                &lt;strong&gt;Breaking change:&lt;/strong&gt; Variant now uses
                variadic templates if they are supported by compiler. This leads
                to smaller binaries and better compilation times but in some cases
                may break metaprogramming functions, especially if &lt;a href=&quot;http://www.boost.org/libs/variant/doc/html/variant/BOOST_VARIANT_ENUM_PARAMS.html&quot;&gt;BOOST_VARIANT_ENUM_PARAMS&lt;/a&gt;
                and &lt;a href=&quot;http://www.boost.org/libs/variant/doc/html/variant/BOOST_VARIANT_ENUM_SHIFTED_PARAMS.html&quot;&gt;BOOST_VARIANT_ENUM_SHIFTED_PARAMS&lt;/a&gt;
                are not used. Usage of variadic templates &lt;a href=&quot;http://www.boost.org/libs/variant/doc/html/variant/BOOST_VARIANT_DO_NOT_USE_VARIADIC_TEMPLATES.html&quot;&gt;may
                be disabled&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;

                &lt;a href=&quot;http://www.boost.org/libs/variant/doc/html/variant/reference.html#header.boost.variant.polymorphic_get_hpp&quot;&gt;Added&lt;/a&gt;
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;polymorphic_get&lt;/span&gt;&lt;/code&gt; function
                &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9479&quot;&gt;#9479&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Move-only classes now can be returned by visitors.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Optimized variant::swap() and fixed ambiguity in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;move_swap&lt;/span&gt;&lt;/code&gt;
                &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2839&quot;&gt;#2839&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added conditional noexcepts to move assignments, default and move
                constructors making &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;variant&lt;/span&gt;&lt;/code&gt;
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;move_if_noexcept&lt;/span&gt;&lt;/code&gt;-friendly
                (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7911&quot;&gt;#7911&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Exceptions are now visible across modules even with -fvisibility=hidden
                flags.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Dropped support of antique compilers.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed some warnings (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3020&quot;&gt;#3020&lt;/a&gt;).
              &lt;/div&gt;

      Support was removed from &lt;a href="http://www.boost.org/libs/config/"&gt;Config&lt;/a&gt; for some
      very old versions of compilers. The new minimum requirements are:
    &lt;/p&gt;
    &lt;ul&gt;
      &lt;li&gt;
        &lt;div&gt;
          Digitial Mars 8.41
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          GCC 3.3
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          Intel 6.0
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          Visual C++ 7.1
        &lt;/div&gt;
      &lt;/li&gt;
    &lt;/ul&gt;
    &lt;p&gt;
      &lt;strong&gt;Note:&lt;/strong&gt; This is just the mininimum requirements
      for Config. Some Boost libraries may have higher mininimum requirements and
      not support all platforms or compilers.
    &lt;/p&gt;
    &lt;p&gt;
      Other compilers are currently unchanged, but we are considering removing support
      for some other old compilers. &lt;strong&gt;Candidates&lt;/strong&gt; for
      removal are:
    &lt;/p&gt;
    &lt;ul&gt;
      &lt;li&gt;
        &lt;div&gt;
          Metroworks C++ (i.e. codewarrior)
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          SunPro 5.7 and earlier
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          Borland C++ Builder 2006 (5.82) and earlier
        &lt;/div&gt;
      &lt;/li&gt;
    &lt;/ul&gt;
    &lt;p&gt;
      If you're using any of these, please let us know on the mailing lists. We will
      take into account any feedback received before making a decision.

  &lt;div id="version_1_55_0.known_bugs"&gt;
    &lt;h3&gt;&lt;span class="link"&gt;Known Bugs with Visual Studio
    2013/Visual C++ 12&lt;/span&gt;&lt;/h3&gt;
    &lt;p&gt;
      Visual Studio 2013 was released quite late in the release process, so there
      exist several unresolved issues. These include:
    &lt;/p&gt;
    &lt;ul&gt;
      &lt;li&gt;
        &lt;div&gt;
          Serialization can't compile because of a missing include.
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          Using &lt;code&gt;&lt;span class="identifier"&gt;has_member_function_callable_with&lt;/span&gt;&lt;/code&gt;
          from Boost.Container's &lt;code&gt;&lt;span class="identifier"&gt;allocator_traits&lt;/span&gt;&lt;/code&gt;
          causes a compile error (&lt;a href="https://svn.boost.org/trac/boost/ticket/9332"&gt;#9332&lt;/a&gt;).
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          In libraries such as Unordered and MultiIndex, calling overloaded functions
          with initializer lists can result in a compile error, with Visual C++ claiming
          that the overloads are ambiguous. This is a Visual C++ bug and it isn't
          clear if there's a good workaround. This won't affect code that doesn't
          use initializer lists, or uses an initializer list that doesn't require
          an implicit conversion (i.e. an initializer list of the container's exact
          value type).
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          Thread: &lt;code&gt;&lt;span class="identifier"&gt;ex_scoped_thread&lt;/span&gt;&lt;/code&gt;
          compile fails (&lt;a href="https://svn.boost.org/trac/boost/ticket/9333"&gt;#9333&lt;/a&gt;).
        &lt;/div&gt;

              &lt;div&gt;
                Implemented a limited port to Windows Runtime. This support requires
                that the language extensions be enabled. Due to the restricted facilities
                exposed by the Windows Runtime API, the port also comes with the
                following caveats:
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      The core facilities such as the &lt;code&gt;&lt;span class="identifier"&gt;io_service&lt;/span&gt;&lt;/code&gt;,
                      &lt;code&gt;&lt;span class="identifier"&gt;strand&lt;/span&gt;&lt;/code&gt;, buffers,
                      composed operations, timers, etc., should all work as normal.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      For sockets, only client-side TCP is supported.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Explicit binding of a client-side TCP socket is not supported.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;

                      The &lt;code&gt;&lt;span class="identifier"&gt;cancel&lt;/span&gt;&lt;span class="special"&gt;()&lt;/span&gt;&lt;/code&gt; function is not supported
                      for sockets. Asynchronous operations may only be cancelled
                      by closing the socket.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Operations that use &lt;code&gt;&lt;span class="identifier"&gt;null_buffers&lt;/span&gt;&lt;/code&gt;
                      are not supported.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Only &lt;code&gt;&lt;span class="identifier"&gt;tcp&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;no_delay&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class="identifier"&gt;socket_base&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;keep_alive&lt;/span&gt;&lt;/code&gt; options are supported.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Resolvers do not support service names, only numbers. I.e.
                      you must use "80" rather than "http".
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Most resolver query flags have no effect.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed a regression (introduced in Boost 1.54) where, on some platforms,
                errors from &lt;code&gt;&lt;span class="identifier"&gt;async_connect&lt;/span&gt;&lt;/code&gt;
                were not correctly propagated through to the completion handler (&lt;a href="https://svn.boost.org/trac/boost/ticket/8795"&gt;#8795&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed a Windows-specific regression (introduced in Boost 1.54) that
                occurs when multiple threads are running an &lt;code&gt;&lt;span class="identifier"&gt;io_service&lt;/span&gt;&lt;/code&gt;.
                When the bug occurs, the result of an asynchronous operation (error
                and bytes transferred) is incorrectly discarded and zero values used
                instead. For TCP sockets this results in spurious end-of-file notifications
                (&lt;a href="https://svn.boost.org/trac/boost/ticket/8933"&gt;#8933&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed a bug in handler tracking, where it was not correctly printing
                out some handler IDs (&lt;a href="https://svn.boost.org/trac/boost/ticket/8808"&gt;#8808&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed the comparison used to test for successful synchronous accept
                operations so that it works correctly with unsigned socket descriptors
                (&lt;a href="https://svn.boost.org/trac/boost/ticket/8752"&gt;#8752&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Ensured the signal number is correctly passed to the completion handler
                when starting an &lt;code&gt;&lt;span class="identifier"&gt;async_wait&lt;/span&gt;&lt;/code&gt;
                on a signal that is already raised (&lt;a href="https://svn.boost.org/trac/boost/ticket/8738"&gt;#8738&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Suppressed a g++ 4.8+ warning about unused typedefs (&lt;a href="https://svn.boost.org/trac/boost/ticket/8980"&gt;#8980&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Enabled the move optimisation for handlers that use the default invocation
                hook (&lt;a href="https://svn.boost.org/trac/boost/ticket/8624"&gt;#8624&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Clarified that programs must not issue overlapping &lt;code&gt;&lt;span class="identifier"&gt;async_write_at&lt;/span&gt;&lt;/code&gt; operations (&lt;a href="https://svn.boost.org/trac/boost/ticket/8669"&gt;#8669&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed the Windows &lt;code&gt;&lt;span class="identifier"&gt;HANDLE&lt;/span&gt;&lt;/code&gt;
                backend to treat &lt;code&gt;&lt;span class="identifier"&gt;ERROR_MORE_DATA&lt;/span&gt;&lt;/code&gt;
                as a non-fatal error when returned by &lt;code&gt;&lt;span class="identifier"&gt;GetOverlappedResult&lt;/span&gt;&lt;/code&gt;
                for a synchronous read (&lt;a href="https://svn.boost.org/trac/boost/ticket/8722"&gt;#8722&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Visual C++ language extensions use &lt;code&gt;&lt;span class="identifier"&gt;generic&lt;/span&gt;&lt;/code&gt;
                as a keyword. Added a workaround that renames the namespace to &lt;code&gt;&lt;span class="identifier"&gt;cpp_generic&lt;/span&gt;&lt;/code&gt; when those language
                extensions are in effect.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed some asynchronous operations that missed out on getting &lt;code&gt;&lt;span class="identifier"&gt;async_result&lt;/span&gt;&lt;/code&gt; support in Boost 1.54.
                In particular, the buffered stream templates have been updated so
                that they adhere to current handler patterns (&lt;a href="https://svn.boost.org/trac/boost/ticket/9000"&gt;#9000&lt;/a&gt;, &lt;a href="https://svn.boost.org/trac/boost/ticket/9001"&gt;#9001&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Enabled move support for Microsoft Visual Studio 2012 (&lt;a href="https://svn.boost.org/trac/boost/ticket/8959"&gt;#8959&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added &lt;code&gt;&lt;span class="identifier"&gt;use_future&lt;/span&gt;&lt;/code&gt;
                support for Microsoft Visual Studio 2012.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Removed a use of &lt;code&gt;&lt;span class="identifier"&gt;std&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;min&lt;/span&gt;&lt;/code&gt;
                in the Windows IOCP backend to avoid a dependency on the &lt;code&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="identifier"&gt;algorithm&lt;/span&gt;&lt;span class="special"&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt; header (&lt;a href="https://svn.boost.org/trac/boost/ticket/8758"&gt;#8758&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Eliminated some unnecessary handler copies.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed various minor and cosmetic issues in code and documentation
                (including &lt;a href="https://svn.boost.org/trac/boost/ticket/8347"&gt;#8347&lt;/a&gt;, &lt;a href="https://svn.boost.org/trac/boost/ticket/8950"&gt;#8950&lt;/a&gt;, &lt;a href="https://svn.boost.org/trac/boost/ticket/8953"&gt;#8953&lt;/a&gt;, &lt;a href="https://svn.boost.org/trac/boost/ticket/8965"&gt;#8965&lt;/a&gt;, &lt;a href="https://svn.boost.org/trac/boost/ticket/8997"&gt;#8997&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class="library"&gt;&lt;a href="http://www.boost.org/libs/atomic/"&gt;Atomic&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added support for 64-bit atomic operations on x86 target for GCC,
                MSVC and compatible compilers. The support is enabled when it is
                known at compile time that the target CPU supports required instructions.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added support for 128-bit atomic operations on x86-64 target for
                GCC and compatible compilers. The support is enabled when it is known
                at compile time that the target CPU supports required instructions.
                The support can be tested for with the new &lt;code&gt;&lt;span class="identifier"&gt;BOOST_ATOMIC_INT128_LOCK_FREE&lt;/span&gt;&lt;/code&gt;
                macro.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added a more efficient implementation of &lt;code&gt;&lt;span class="identifier"&gt;atomic&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt; based on GCC &lt;code&gt;&lt;span class="identifier"&gt;__atomic&lt;/span&gt;&lt;span class="special"&gt;*&lt;/span&gt;&lt;/code&gt;
                intrinsics available since GCC 4.7.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added support for more ARM v7 CPUs, improved detection of Thumb 2.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added support for x32 (i.e. 64-bit x86 with 32-bit pointers) target
                on GCC and compatible compilers.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Removed dependency on Boost.Thread.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Internal lock pool now includes proper padding and alignment to avoid
                false sharing.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed compilation with Intel compiler on Windows. Removed internal
                macro duplication when compiled on Windows.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Some code refactoring to use C++11 features when available.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;

              &lt;div&gt;
                &lt;em&gt;Fixed Bugs:&lt;/em&gt;
                &lt;ul&gt;
                  &lt;li&gt;

                      time incorrectly (1.53 and 1.52)
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;

                      &lt;a href="http://svn.boost.org/trac/boost/ticket/9028"&gt;#9028&lt;/a&gt;
                      Typo in &lt;code&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;chrono&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;stopwatches&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;formatters&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;base_formatter&lt;/span&gt;&lt;span class="special"&gt;.&lt;/span&gt;&lt;span class="identifier"&gt;hpp&lt;/span&gt;&lt;/code&gt;
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      &lt;a href="http://svn.boost.org/trac/boost/ticket/9147"&gt;#9147&lt;/a&gt;
                      uninitialized &lt;code&gt;&lt;span class="identifier"&gt;std&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;tm&lt;/span&gt;&lt;/code&gt;
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class="library"&gt;&lt;a href="http://www.boost.org/libs/circular_buffer/"&gt;Circular Buffer&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added support for rvalue references and rvalue references emulation
                using Boost.Move. Values are moved only if value type has noexcept
                move constructor and noexcept move assignment operator &lt;a href="https://svn.boost.org/trac/boost/ticket/7888"&gt;#7888&lt;/a&gt;.
                Now Circular Buffer is usable with move-only types.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Much better documentation.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                &lt;a href="http://svn.boost.org/trac/boost/ticket/5362"&gt;#5362&lt;/a&gt;
                circular_buffer does not compile with &lt;code&gt;&lt;span class="identifier"&gt;BOOST_NO_EXCEPTIONS&lt;/span&gt;&lt;/code&gt;.
              &lt;/div&gt;
            &lt;/li&gt;

                causing severe bugs when values to be inserted where allocated next

                Big refactoring in order to reduce template and debug symbol bloat.
                Test object files have been slashed to half in MSVC compilers in
                Debug mode. Toolchains without Identical COMDAT Folding (ICF) should
                notice size improvements.

            &lt;li&gt;

                General changes:
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added a new configuration macro &lt;code&gt;&lt;span class="identifier"&gt;BOOST_LOG_WITHOUT_DEFAULT_FACTORIES&lt;/span&gt;&lt;/code&gt;.
                      By defining this macro the user can disable compilation of
                      the default filter and formatter factories used by settings
                      parsers. This can substantially reduce binary sizes while still
                      retaining support for settings parsers.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Rewritten some of the parsers to reduce the compiled binary
                      size. The rewritten parsers are more robust in detecting ambiguous
                      and incorrect input.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      The following headers are deprecated: &lt;code&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;log&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;utility&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;intrusive_ref_counter&lt;/span&gt;&lt;span class="special"&gt;.&lt;/span&gt;&lt;span class="identifier"&gt;hpp&lt;/span&gt;&lt;/code&gt;,
                      &lt;code&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;log&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;utility&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;explicit_operator_bool&lt;/span&gt;&lt;span class="special"&gt;.&lt;/span&gt;&lt;span class="identifier"&gt;hpp&lt;/span&gt;&lt;/code&gt;, &lt;code&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;log&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;utility&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;empty_deleter&lt;/span&gt;&lt;span class="special"&gt;.&lt;/span&gt;&lt;span class="identifier"&gt;hpp&lt;/span&gt;&lt;/code&gt;.
                      These headers will be removed in future releases. The contents
                      of these headers were moved to other libraries.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;

                  &lt;li&gt;
                    &lt;div&gt;
                      Fixed a bug in the filter parser that prevented using parsed
                      filters with some attributes.
                    &lt;/div&gt;
                  &lt;/li&gt;

                dynamic_properties objects can now be built by non-destructively
                chaining &lt;code&gt;&lt;span class="special"&gt;.&lt;/span&gt;&lt;span class="identifier"&gt;property&lt;/span&gt;&lt;span class="special"&gt;(&lt;/span&gt;&lt;span class="identifier"&gt;name&lt;/span&gt;&lt;span class="special"&gt;,&lt;/span&gt; &lt;span class="identifier"&gt;pm&lt;/span&gt;&lt;span class="special"&gt;)&lt;/span&gt;&lt;/code&gt; calls. Example:
              &lt;/div&gt;
&lt;pre&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;dynamic_properties&lt;/span&gt;&lt;span class="special"&gt;()&lt;/span&gt;
  &lt;span class="special"&gt;.&lt;/span&gt;&lt;span class="identifier"&gt;property&lt;/span&gt;&lt;span class="special"&gt;(&lt;/span&gt;&lt;span class="string"&gt;"color"&lt;/span&gt;&lt;span class="special"&gt;,&lt;/span&gt; &lt;span class="identifier"&gt;color_map&lt;/span&gt;&lt;span class="special"&gt;)&lt;/span&gt;
  &lt;span class="special"&gt;.&lt;/span&gt;&lt;span class="identifier"&gt;property&lt;/span&gt;&lt;span class="special"&gt;(&lt;/span&gt;&lt;span class="string"&gt;"pos"&lt;/span&gt;&lt;span class="special"&gt;,&lt;/span&gt; &lt;span class="identifier"&gt;position_map&lt;/span&gt;&lt;span class="special"&gt;)&lt;/span&gt;

            &lt;li&gt;
              &lt;div&gt;
                The use of raw pointers as property maps is deprecated; it often
                failed on Visual Studio in the past. This usage has been removed
                from all tests and examples in Boost.Graph. The replacement to use
                for vertex properties in graphs (the most common use for this feature)
                is:
              &lt;/div&gt;
&lt;pre&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;make_iterator_property_map&lt;/span&gt;&lt;span class="special"&gt;(&lt;/span&gt;
  &lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="identifier"&gt;pointer&lt;/span&gt; &lt;span class="keyword"&gt;or&lt;/span&gt; &lt;span class="identifier"&gt;container&lt;/span&gt; &lt;span class="special"&gt;.&lt;/span&gt;&lt;span class="identifier"&gt;begin&lt;/span&gt;&lt;span class="special"&gt;()&lt;/span&gt; &lt;span class="identifier"&gt;iterator&lt;/span&gt;&lt;span class="special"&gt;&amp;gt;,&lt;/span&gt;
  &lt;span class="identifier"&gt;get&lt;/span&gt;&lt;span class="special"&gt;(&lt;/span&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;vertex_index&lt;/span&gt;&lt;span class="special"&gt;,&lt;/span&gt; &lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="identifier"&gt;graph&lt;/span&gt; &lt;span class="identifier"&gt;object&lt;/span&gt;&lt;span class="special"&gt;&amp;gt;))&lt;/span&gt;
&lt;/pre&gt;
              &lt;div&gt;
                (Note: the lack of namespace qualification on get() in this code
                is necessary for generic code). Outside a graph context, the closest
                equivalent is:
              &lt;/div&gt;
&lt;pre&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;make_iterator_property_map&lt;/span&gt;&lt;span class="special"&gt;(&lt;/span&gt;
  &lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="identifier"&gt;pointer&lt;/span&gt;&lt;span class="special"&gt;&amp;gt;,&lt;/span&gt;
  &lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;typed_identity_property_map&lt;/span&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="identifier"&gt;std&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;size_t&lt;/span&gt;&lt;span class="special"&gt;&amp;gt;())&lt;/span&gt;
&lt;/pre&gt;
              &lt;div&gt;
                There are commented-out static assertions on lines 151 and 159 of
                &lt;code&gt;&lt;span class="special"&gt;&amp;lt;&lt;/span&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;property_map&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;property_map&lt;/span&gt;&lt;span class="special"&gt;.&lt;/span&gt;&lt;span class="identifier"&gt;hpp&lt;/span&gt;&lt;span class="special"&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt; that can be un-commented to find
                deprecated uses of pointers in user code.
              &lt;/div&gt;
            &lt;/li&gt;

            &lt;li&gt;
              &lt;div&gt;
                Added &lt;code&gt;&lt;span class="identifier"&gt;lowest&lt;/span&gt;&lt;/code&gt; and
                &lt;code&gt;&lt;span class="identifier"&gt;max_digits10&lt;/span&gt;&lt;/code&gt;, members
                of std::numeric_limits added in C++11, to the unit-test code. Needed
                since Boost.Test refers to one of them when compiled in C++11 mode.

                cannot be a narrowing conversion, which fixes issue &lt;a href="https://svn.boost.org/trac/boost/ticket/5855"&gt;#5855&lt;/a&gt;. Needed
                since narrowing conversions are an error in C++11.
              &lt;/div&gt;
            &lt;/li&gt;

                The header implements a mixin base class that adds support for &lt;code&gt;&lt;span class="identifier"&gt;intrusive_ptr&lt;/span&gt;&lt;/code&gt; to user's classes.

                Fixed compilation on Intel compiler &lt;a href="https://svn.boost.org/trac/boost/ticket/8956"&gt;#8956&lt;/a&gt;.

            &lt;li&gt;
              &lt;div&gt;
                Added &lt;code&gt;&lt;span class="identifier"&gt;is_copy_contructible&lt;/span&gt;&lt;/code&gt;

            &lt;li&gt;
              &lt;div&gt;
                Avoid some warnings (&lt;a href="https://svn.boost.org/trac/boost/ticket/8851"&gt;#8851&lt;/a&gt;, &lt;a href="https://svn.boost.org/trac/boost/ticket/8874"&gt;#8874&lt;/a&gt;).

            &lt;li&gt;

            &lt;li&gt;
              &lt;div&gt;
                Work around variadic parameter bug in Visual Studio 2013. The compiler
                still has problems with initializer lists, but it might not be possible
                to work around those.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;

          &lt;span class="library"&gt;&lt;a href="http://www.boost.org/libs/utility/index.html"&gt;Utility&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                &lt;code&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;result_of&lt;/span&gt;&lt;/code&gt; can be set to use TR1
                protocol by default and fall back to &lt;code&gt;&lt;span class="keyword"&gt;decltype&lt;/span&gt;&lt;/code&gt;
                if the function object does not support it (like C++11 lambda functions,
                for example). Define &lt;code&gt;&lt;span class="identifier"&gt;BOOST_RESULT_OF_USE_TR1_WITH_DECLTYPE_FALLBACK&lt;/span&gt;&lt;/code&gt;
                configuration macro to enable this mode.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Improved support for C++11 in the &lt;code&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;::&lt;/span&gt;&lt;span class="identifier"&gt;base_from_member&lt;/span&gt;&lt;/code&gt;
                class template. The class implements perfect forwarding for the constructor
                arguments, if the compiler supports rvalue references, variadic templates
                and function template default arguments.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added &lt;code&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;utility&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;explicit_operator_bool&lt;/span&gt;&lt;span class="special"&gt;.&lt;/span&gt;&lt;span class="identifier"&gt;hpp&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class="identifier"&gt;boost&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;utility&lt;/span&gt;&lt;span class="special"&gt;/&lt;/span&gt;&lt;span class="identifier"&gt;empty_deleter&lt;/span&gt;&lt;span class="special"&gt;.&lt;/span&gt;&lt;span class="identifier"&gt;hpp&lt;/span&gt;&lt;/code&gt;
                headers, which were extracted from Boost.Log. The headers implement
                utilities for defining explicit conversion operators to &lt;code&gt;&lt;span class="keyword"&gt;bool&lt;/span&gt;&lt;/code&gt; and a deleter function object
                that does nothing, respectively.
              &lt;/div&gt;
            &lt;/li&gt;

            &lt;li&gt;
              &lt;div&gt;
                Fixed compilation of constructor and assignment operator with const
                rvalues input parameters &lt;a href="https://svn.boost.org/trac/boost/ticket/8988"&gt;#8988&lt;/a&gt;.

            &lt;li&gt;
              &lt;div&gt;
                Fixed compilation of move assignment operator for situations when
                one of the variant template classes has nothrow copy constructor
                and throwing move constructor &lt;a href="https://svn.boost.org/trac/boost/ticket/8772"&gt;#8772&lt;/a&gt;.
              &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;
                Fix compilation on exception-disabled environments &lt;a href="https://svn.boost.org/trac/boost/ticket/8717"&gt;#8717&lt;/a&gt;.
              &lt;/div&gt;

            &lt;li&gt;

                Fix unreachable code warnings &lt;a href="https://svn.boost.org/trac/boost/ticket/8665"&gt;#8665&lt;/a&gt;.

  &lt;div id=&quot;version_1_54_0.patches&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;Patches&lt;/span&gt;&lt;/h3&gt;
    &lt;p&gt;
      These are patches from library authors which were found too late to be fixed
      in the 1.54.0 release. Be careful as they have not been through the normal
      testing process.
    &lt;/p&gt;
    &lt;ol&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;a href=&quot;http://www.boost.org/patches/1_54_0/001-coroutine.patch&quot;&gt;Coroutine patch&lt;/a&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;a href=&quot;http://www.boost.org/patches/1_54_0/002-date-time.patch&quot;&gt;Date Time patch&lt;/a&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;a href=&quot;http://www.boost.org/patches/1_54_0/003-log.patch&quot;&gt;Log patch&lt;/a&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;a href=&quot;http://www.boost.org/patches/1_54_0/004-thread.patch&quot;&gt;Thread patch&lt;/a&gt;
        &lt;/div&gt;
      &lt;/li&gt;
    &lt;/ol&gt;
  &lt;/div&gt;
  &lt;div id=&quot;version_1_54_0.news&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;News&lt;/span&gt;&lt;/h3&gt;
    &lt;div id=&quot;version_1_54_0.news.supported_cpus&quot;&gt;
      &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;Supported CPUs&lt;/span&gt;&lt;/h3&gt;
      &lt;p&gt;
        Boost no longer supports the 80386 target CPU, the minimum x86 32-bit target
        is i486. The 80386 target was not properly supported by &lt;a href=&quot;http://www.boost.org/libs/smart_ptr/&quot;&gt;Boost.SmartPtr&lt;/a&gt;
        and &lt;a href=&quot;http://www.boost.org/libs/atomic/&quot;&gt;Boost.Atomic&lt;/a&gt; (as well as the libraries
        that used them internally) even before this release. Some Boost libraries
        may have higher requirements on the minimum target CPU (like &lt;a href=&quot;http://www.boost.org/libs/log/&quot;&gt;Boost.Log&lt;/a&gt;
        for example), see the respective library documentation for details.
      &lt;/p&gt;
      &lt;p&gt;
        Also by default, when building Boost for x86 32-bit targets it will compile
        for i686 (Pentium Pro) and later CPUs. This can be changed by specifying
        the &lt;tt&gt;instruction-set&lt;/tt&gt; property in &lt;tt&gt;b2&lt;/tt&gt;
        or &lt;tt&gt;bjam&lt;/tt&gt; command line, for example:
      &lt;/p&gt;
&lt;pre&gt;b2 variant=release architecture=x86 instruction-set=i486 stage
&lt;/pre&gt;
      &lt;p&gt;
        Possible values for the &lt;tt&gt;instruction-set&lt;/tt&gt; are:
      &lt;/p&gt;
      &lt;ul&gt;
        &lt;li&gt;
          &lt;div&gt;
            Target for the host CPU: &lt;tt&gt;native&lt;/tt&gt;
          &lt;/div&gt;
        &lt;/li&gt;
        &lt;li&gt;
          &lt;div&gt;
            Generic x86 CPUs: &lt;tt&gt;i486&lt;/tt&gt;, &lt;tt&gt;i586&lt;/tt&gt;,
            &lt;tt&gt;i686&lt;/tt&gt;
          &lt;/div&gt;
        &lt;/li&gt;
        &lt;li&gt;
          &lt;div&gt;
            Intel CPUs: &lt;tt&gt;pentium&lt;/tt&gt;, &lt;tt&gt;pentium-mmx&lt;/tt&gt;,
            &lt;tt&gt;pentiumpro&lt;/tt&gt;, &lt;tt&gt;pentium2&lt;/tt&gt;, &lt;tt&gt;pentium3&lt;/tt&gt;,
            &lt;tt&gt;pentium3m&lt;/tt&gt;, &lt;tt&gt;pentium-m&lt;/tt&gt;, &lt;tt&gt;pentium4&lt;/tt&gt;,

            &lt;tt&gt;core-avx-i&lt;/tt&gt;, &lt;tt&gt;conroe&lt;/tt&gt;, &lt;tt&gt;conroe-xe&lt;/tt&gt;,

            &lt;tt&gt;btver2&lt;/tt&gt;
          &lt;/div&gt;

        &lt;/li&gt;
      &lt;/ul&gt;
      &lt;p&gt;
        Note that not all these values may be supported by a particular compiler.
      &lt;/p&gt;
    &lt;/div&gt;
    &lt;div id=&quot;version_1_54_0.news.signals_deprecated&quot;&gt;
      &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;Signals deprecated&lt;/span&gt;&lt;/h3&gt;
      &lt;p&gt;
        Boost.Signals is no longer being actively maintained, so it has been deprecated.
        Do not use Boost.Signals for new development (use &lt;a href=&quot;http://www.boost.org/libs/signals2/&quot;&gt;Boost.Signals2&lt;/a&gt;
        instead). If you have existing Boost.Signals-based code, it will continue
        to work, but consider moving to Boost.Signals2. There is &lt;a href=&quot;http://www.boost.org/doc/html/signals2/api_changes.html#signals2.porting&quot;&gt;a
        porting guide&lt;/a&gt; in the Signals2 documentation.

            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Silence unused variable warnings (&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/6926&quot;&gt;#6926&lt;/a&gt;)
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                The return types for copy_while and copy_until have been changed.
                This is an interface change. If you were using the return values
                from these functions, then you will have to modify your code. Instead
                of just returning the modified &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;OutputIterator&lt;/span&gt;&lt;/code&gt;,
                these functions now return a &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;std&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;pair&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;InputIterator&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;,&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;OutputIterator&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;. If this change affects your
                code, the simplest change is to add a &lt;code&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;second&lt;/span&gt;&lt;/code&gt; to the end of the call,
                which will get you the same behavior that you had before.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added C++14 versions of 'is_permutation', 'equal' and 'mismatch'.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/any/&quot;&gt;Any&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added C++11 features support &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6999&quot;&gt;#6999&lt;/a&gt;:
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Move assignment and move constructors.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;noexcept&lt;/span&gt;&lt;/code&gt;
                      modifiers.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/asio/&quot;&gt;Asio&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added new traits classes, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;handler_type&lt;/span&gt;&lt;/code&gt;
                and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;async_result&lt;/span&gt;&lt;/code&gt;,
                that allow the customisation of the return type of an initiating
                function.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;asio&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;spawn&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
                function, a high-level wrapper for running stackful coroutines, based
                on the Boost.Coroutine library. The &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;spawn&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; function enables programs to implement
                asynchronous logic in a synchronous manner. For example: &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;size_t&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;n&lt;/span&gt;
                &lt;span class=&quot;special&quot;&gt;=&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;my_socket&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;async_read_some&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;my_buffer&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;,&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;yield&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;);&lt;/span&gt;&lt;/code&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;asio&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;use_future&lt;/span&gt;&lt;/code&gt; special value, which
                provides first-class support for returning a C++11 &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;std&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;future&lt;/span&gt;&lt;/code&gt; from an asynchronous operation's
                initiating function. For example: &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;future&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;size_t&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;n&lt;/span&gt;
                &lt;span class=&quot;special&quot;&gt;=&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;my_socket&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;async_read_some&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;my_buffer&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;,&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;asio&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;use_future&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;);&lt;/span&gt;&lt;/code&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Promoted the stackless coroutine class and macros to be part of Asio's
                documented interface, rather than part of the HTTP server 4 example.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added a new handler hook called &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;asio_handler_is_continuation&lt;/span&gt;&lt;/code&gt;.
                Asynchronous operations may represent a continuation of the asynchronous
                control flow associated with the current executing handler. The
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;asio_handler_is_continuation&lt;/span&gt;&lt;/code&gt;
                hook can be customised to return &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;true&lt;/span&gt;&lt;/code&gt;
                if this is the case, and Asio's implementation can use this knowledge
                to optimise scheduling of the new handler. To cover common cases,
                Asio customises the hook for strands, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;spawn&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; and composed asynchronous operations.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added four new generic protocol classes, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;generic&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;datagram_protocol&lt;/span&gt;&lt;/code&gt;,
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;generic&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;raw_protocol&lt;/span&gt;&lt;/code&gt;, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;generic&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;seq_packet_protocol&lt;/span&gt;&lt;/code&gt;
                and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;generic&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;stream_protocol&lt;/span&gt;&lt;/code&gt;, which implement
                the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;Protocol&lt;/span&gt;&lt;/code&gt; type
                requirements, but allow the user to specify the address family (e.g.
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;AF_INET&lt;/span&gt;&lt;/code&gt;) and protocol
                type (e.g. &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;IPPROTO_TCP&lt;/span&gt;&lt;/code&gt;)
                at runtime.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added C++11 move constructors that allow the conversion of a socket
                (or acceptor) into a more generic type. For example, an &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ip&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;tcp&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;socket&lt;/span&gt;&lt;/code&gt; can be converted into a
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;generic&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;stream_protocol&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;socket&lt;/span&gt;&lt;/code&gt; via move construction.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Extended the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;basic_socket_acceptor&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt; class's &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;accept&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;async_accept&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; functions to allow a new connection
                to be accepted directly into a socket of a more generic type. For
                example, an &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ip&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;tcp&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;acceptor&lt;/span&gt;&lt;/code&gt; can be used to accept
                into a &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;generic&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;stream_protocol&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;socket&lt;/span&gt;&lt;/code&gt; object.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Moved existing examples into a C++03-specific directory, and added
                a new directory for C++11-specific examples. A limited subset of
                the C++03 examples have been converted to their C++11 equivalents.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Various SSL enhancements. Thanks go to Nick Jones, on whose work
                these changes are based.
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added support for SSL handshakes with re-use of data already
                      read from the wire. New overloads of the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ssl&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;stream&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt; class's &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;handshake&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
                      and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;async_handshake&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; functions have been added.
                      These accept a &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ConstBufferSequence&lt;/span&gt;&lt;/code&gt;
                      to be used as initial input to the ssl engine for the handshake
                      procedure.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added support for creation of TLSv1.1 and TLSv1.2 &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ssl&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;context&lt;/span&gt;&lt;/code&gt; objects.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added a &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;set_verify_depth&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; function to the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ssl&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;context&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ssl&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;stream&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt;
                      classes.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added the ability to load SSL certificate and key data from
                      memory buffers. New functions, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;add_certificate_authority&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;use_certificate&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;use_certificate_chain&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;use_private_key&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;use_rsa_private_key&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;use_tmp_dh&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;, have been added to the
                      &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ssl&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;context&lt;/span&gt;&lt;/code&gt; class.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Changed &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ssl&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;context&lt;/span&gt;&lt;/code&gt;
                      to automatically disable SSL compression by default. To enable,
                      use the new &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ssl&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;context&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;clear_options&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; function, as in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;my_context&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;clear_options&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;ssl&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;context&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;no_compression&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)&lt;/span&gt;&lt;/code&gt;.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed a potential deadlock in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;signal_set&lt;/span&gt;&lt;/code&gt;
                implementation.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed an error in acceptor example in documentation &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8421&quot;&gt;#8421&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed copy-paste errors in waitable timer documentation &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8602&quot;&gt;#8602&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added assertions to satisfy some code analysis tools &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7739&quot;&gt;#7739&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed a malformed &lt;code&gt;&lt;span class=&quot;preprocessor&quot;&gt;#warning&lt;/span&gt;&lt;/code&gt;
                directive &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7939&quot;&gt;#7939&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed a potential data race in the Linux &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;epoll&lt;/span&gt;&lt;/code&gt;
                implementation.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed a Windows-specific bug, where certain operations might generate
                an &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;error_code&lt;/span&gt;&lt;/code&gt; with
                an invalid (i.e. &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;NULL&lt;/span&gt;&lt;/code&gt;)
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;error_category&lt;/span&gt;&lt;/code&gt; &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8613&quot;&gt;#8613&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;basic_waitable_timer&lt;/span&gt;&lt;/code&gt;'s
                underlying implementation so that it can handle any &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;time_point&lt;/span&gt;&lt;/code&gt; value without overflowing
                the intermediate duration objects.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed a problem with lost thread wakeups that can occur when making
                concurrent calls to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;run&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;poll&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; on the same &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;io_service&lt;/span&gt;&lt;/code&gt;
                object &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8354&quot;&gt;#8354&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed implementation of asynchronous connect operation so that it
                can cope with spurious readiness notifications from the reactor &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7961&quot;&gt;#7961&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;

          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/chrono/&quot;&gt;Chrono&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                &lt;em&gt;Fixed Bugs:&lt;/em&gt;
                &lt;ul&gt;
                  &lt;li&gt;

              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added updates to VF2 subgraph isomorphism from Jakob Lykke Andersen
                and Flavio De Lorenzi.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added maximum adjacency search from Fernando Vilas.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added timeout support from Brammert Ottens to resource-constrained
                shortest paths (r_c_shortest_paths) algorithm.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Various fixes to documentation and examples and removal of outdated
                compiler workarounds.
              &lt;/div&gt;
            &lt;/li&gt;

            &lt;li&gt;
              &lt;div&gt;
                Added support for platform-specific flags to mapped_region (ticket
                #8030)
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;

            &lt;li&gt;
              &lt;div&gt;
                &lt;strong&gt;ABI breaking&lt;/strong&gt;: Changed bootstamp
                function in Windows to use EventLog service start time as system
                bootup time. Previously used &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;LastBootupTime&lt;/span&gt;&lt;/code&gt;
                from WMI was unstable with time synchronization and hibernation and
                unusable in practice. If you really need to obtain pre Boost 1.54
                behaviour define &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_INTERPROCESS_BOOTSTAMP_IS_LASTBOOTUPTIME&lt;/span&gt;&lt;/code&gt;
                from command line or &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;detail&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;workaround&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;/code&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_NO_EXCEPTIONS&lt;/span&gt;&lt;/code&gt;
                support (bug &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7849&quot;&gt;#7849&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;

                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;tee&lt;/span&gt;&lt;/code&gt; now works correctly
                for std::streams (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8315&quot;&gt;#8315&lt;/a&gt;).

            &lt;li&gt;
              &lt;div&gt;
                Avoid warning from Clang's &lt;code&gt;&lt;span class=&quot;special&quot;&gt;-&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;Wimplicit&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;-&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;fallthrough&lt;/span&gt;&lt;/code&gt; (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8482&quot;&gt;#8482&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;

            &lt;li&gt;
              &lt;div&gt;
                Converting to character pointer now triggers compile time assert
                instead of runtime &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8334&quot;&gt;#8334&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Lexical cast is now capable of converting &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;int128_type&lt;/span&gt;&lt;/code&gt;
                and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;uint128_type&lt;/span&gt;&lt;/code&gt; &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7909&quot;&gt;#7909&lt;/a&gt;.

            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed internal stream buffer handling, now works with libc++ &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8267&quot;&gt;#8267&lt;/a&gt;,
                &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7704&quot;&gt;#7704&lt;/a&gt;.
              &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;
                Restored getting address of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;lexical_cast&lt;/span&gt;&lt;/code&gt;
                function that was broken in 1.53.0 &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7421&quot;&gt;#7421&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed warnings, internals and tests &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2558&quot;&gt;#2558&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7949&quot;&gt;#7949&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8162&quot;&gt;#8162&lt;/a&gt;,

              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/math/&quot;&gt;Math&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Major reorganization to incorporate other Boost.Math like Integer
                Utilities (Greatest Common Divisor and Least Common Multiple), quaternions
                and octonions. Making new chapter headings.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added many references to Boost.Multiprecision and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;cpp_dec_float_50&lt;/span&gt;&lt;/code&gt;
                as an example of a User-defined Type (UDT).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added Clang to list of supported compilers.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed constants to use a thread-safe cache of computed values when
                used at arbitrary precision.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added finding zeros of Bessel functions &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;cyl_bessel_j_zero&lt;/span&gt;&lt;/code&gt;,
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;cyl_neumann_zero&lt;/span&gt;&lt;/code&gt;,
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;airy_ai_zeros&lt;/span&gt;&lt;/code&gt; and
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;airy_bi_zeros&lt;/span&gt;&lt;/code&gt;(by
                Christopher Kormanyos).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                More accuracy improvements to the Bessel J and Y functions from Rocco
                Romeo.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed nasty cyclic dependency bug that caused some headers to not
                compile &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7999&quot;&gt;#7999&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed bug in __tgamma that caused spurious overflow for arguments
                between 142.5 and 143.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed bug in raise_rounding_error that caused it to return an incorrect
                result when throwing an exception is turned off &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7905&quot;&gt;#7905&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added minimal __float128 support.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed bug in edge-cases of poisson quantile &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8308&quot;&gt;#8308&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Adjusted heuristics used in Halley iteration to cope with inverting
                the incomplete beta in tricky regions where the derivative is flatlining.
                Example is computing the quantile of the Fisher F distribution for
                probabilities smaller than machine epsilon. See ticket &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8314&quot;&gt;#8314&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;

            &lt;li&gt;
              &lt;div&gt;
                Bugfix: Exit points broken for the favor_compile_time policy.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Bugfix: copy breaks exit points of subsubmachines.

                that results in incorrect value when the result should have a 0 in

                where division of 0 by something doesn't get zero in the result:

                Fixed bug in some transcendental functions that caused incorrect

            &lt;li&gt;
              &lt;div&gt;
                Changed to use &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;_snwprintf&lt;/span&gt;&lt;/code&gt;
                to address a compile error due to the changed &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;swprintf&lt;/span&gt;&lt;/code&gt;
                signature in recent versions of MinGW (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7373&quot;&gt;#7373&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed a deadlock that can occur on Windows when shutting down a pool
                of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;io_service&lt;/span&gt;&lt;/code&gt; threads
                due to running out of work (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7552&quot;&gt;#7552&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Enabled the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;noexcept&lt;/span&gt;&lt;/code&gt;
                qualifier for error categories (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7797&quot;&gt;#7797&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed UNIX domain socket example to treat errors from &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;accept&lt;/span&gt;&lt;/code&gt; as non-fatal (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7488&quot;&gt;#7488&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added a small block recycling optimisation to improve default memory
                allocation behaviour.
              &lt;/div&gt;
            &lt;/li&gt;

            &lt;li&gt;
              &lt;div&gt;
                Fixed replace_(left/right/key/data) bug when using relations with
                info.
              &lt;/div&gt;

            &lt;li&gt;

            &lt;li&gt;

                      The chrono i/o version included in Boost.Chrono 1.2.x has been
                      completly refactored in version 2.0.0

                      You should use the __get_duration_style free function to get
                      the informations and use the __duration_units facet for localization
                      purposes.

            &lt;li&gt;

                insertion performance.
              &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;
                Changed again experimental multiallocation interface for better performance
                (still experimental).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added no exception support for those willing to disable exceptions
                in their compilers.
              &lt;/div&gt;

                  &lt;li&gt;
                    &lt;div&gt;
                      Glen Fernandes provided implementations of make_shared and
                      allocate_shared for arrays. They achieve a single allocation
                      for an array that can be initialized with constructor arguments
                      or initializer lists as well as overloads for default initialization
                      and no value initialization. See the '&lt;a href=&quot;http://www.boost.org/libs/smart_ptr/make_shared_array.html&quot;&gt;make_shared
                      and allocate_shared for arrays&lt;/a&gt;' page for more information.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;shared_ptr&lt;/span&gt;&lt;/code&gt;
                      can now be used to hold a pointer to a dynamically allocated
                      array. This is accomplished by using an array type (&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;T&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;[]&lt;/span&gt;&lt;/code&gt;
                      or &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;T&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;[&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;N&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;]&lt;/span&gt;&lt;/code&gt;)
                      as the template parameter.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Smart pointers now use &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;explicit&lt;/span&gt;
                      &lt;span class=&quot;keyword&quot;&gt;operator&lt;/span&gt; &lt;span class=&quot;keyword&quot;&gt;bool&lt;/span&gt;&lt;/code&gt;
                      on C++11 compilers. This can break code that passes a smart
                      pointer to a function taking a &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;bool&lt;/span&gt;&lt;/code&gt;,
                      or that returns a smart pointer from a function with a &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;bool&lt;/span&gt;&lt;/code&gt; return type. Please use
                      &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;p&lt;/span&gt; &lt;span class=&quot;special&quot;&gt;!=&lt;/span&gt;
                      &lt;span class=&quot;number&quot;&gt;0&lt;/span&gt;&lt;/code&gt; or &lt;code&gt;&lt;span class=&quot;special&quot;&gt;!!&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;p&lt;/span&gt;&lt;/code&gt; in such cases.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;

            &lt;li&gt;
              &lt;div&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Remove support for the old pre-standard variadic pair constructors,
                and equality implementation. Both have been deprecated since Boost
                1.48.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                More internal implementation changes, including a much simpler implementation
                of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;erase&lt;/span&gt;&lt;/code&gt;, and removed
                more deprecated config macros.
              &lt;/div&gt;
            &lt;/li&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added &lt;a href=&quot;http://www.boost.org/libs/utility/doc/html/string_ref.html&quot;&gt;string_ref&lt;/a&gt;,
                a non-owning reference to a contiguous sequence of characters.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added rvalue constructors and rvalue assignment operators (for C++11
                compatible compilers only). Library now can be used with move-only
                types (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7620&quot;&gt;#7620&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7718&quot;&gt;#7718&lt;/a&gt;).

                      The chrono i/o version included in Boost.Chrono 1.2.x has been
                      completly refactored in version 2.0.0
                    &lt;/div&gt;

                      are depreceated. You should use the parameterized form &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;__duration_fmt&lt;/span&gt;&lt;/code&gt; or the renamed
                      manipulators &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;__duration_symbol&lt;/span&gt;&lt;/code&gt;
                      and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;__duration_prefix&lt;/span&gt;&lt;/code&gt;
                      instead.

                      You should use the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;__get_duration_style&lt;/span&gt;&lt;/code&gt;
                      free function to get the informations and use the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;__duration_units&lt;/span&gt;&lt;/code&gt; facet for

                copies). This should greatly increase performance but breaks ABI.
                Old behaviour/ABI can be used undefining macro &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_INTERPROCESS_MSG_QUEUE_CIRCULAR_INDEX&lt;/span&gt;&lt;/code&gt;
                in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;interprocess&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;detail&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;workaround&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;/code&gt;
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Improved &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;message_queue&lt;/span&gt;&lt;/code&gt;
                insertion time avoiding priority search for common cases (both array
                and circular buffer configurations).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Implemented &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;interproces_sharable_mutex&lt;/span&gt;&lt;/code&gt;
                and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;interproces_condition_any&lt;/span&gt;&lt;/code&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Improved &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;offset_ptr&lt;/span&gt;&lt;/code&gt;
                performance.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added integer overflow checks.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed:

                  &lt;li&gt;
                    &lt;div&gt;
                      &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5825&quot;&gt;#5825&lt;/a&gt; constructing function_input_iterator without consuming
                      an item
                    &lt;/div&gt;

                  &lt;li&gt;
                    &lt;div&gt;
                      &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7194&quot;&gt;#7194&lt;/a&gt; Error in documentation of make_function_input_iterator
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                &lt;em&gt;Breaking changes:&lt;/em&gt;
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Due to the fix for &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5825&quot;&gt;#5825&lt;/a&gt;, a function_input_iterator will
                      no longer make unnecessary invokations to the wrapped nullary
                      function. For example, constructing an end iterator will now
                      not trigger an invokation; and dereferencing-and-incrementing
                      an iterator N times will trigger N invokations, not N+1 as
                      before. User code that relied on the old behavior will need
                      to be adjusted.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;

            &lt;li&gt;
              &lt;div&gt;
                Restored compilation on MSVC-2003 (was broken in 1.51.0) &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7255&quot;&gt;#7255&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;lexical_cast&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;keyword&quot;&gt;const&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;CharType&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;*&lt;/span&gt;
                &lt;span class=&quot;identifier&quot;&gt;chars&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;,&lt;/span&gt;
                &lt;span class=&quot;identifier&quot;&gt;std&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;size_t&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;count&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)&lt;/span&gt;&lt;/code&gt; function overload. &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6663&quot;&gt;#6663&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed bug &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7228&quot;&gt;#7228&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added Airy functions and Jacobi Elliptic functions.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                In several distributions (particulary the Students T) corrected moments
                for small degrees of freedom &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7177&quot;&gt;#7177&lt;/a&gt;
                (reported by Thomas Mang).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Corrected failure to detect bad parameters in many distributions
                &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6934&quot;&gt;#6934&lt;/a&gt;
                (reported by Florian Schoppmann) by adding a function &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;check_out_of_range&lt;/span&gt;&lt;/code&gt; to test many
                possible bad parameters. This test revealed several distributions
                where the checks for bad parameters were ineffective, and these have
                been rectified.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed issue in Hankel functions that causes incorrect values to be
                returned for &lt;em&gt;x &amp;lt; 0&lt;/em&gt; and &lt;em&gt;ν&lt;/em&gt;
                odd, see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7135&quot;&gt;#7135&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                In non-central T permitted infinite degrees of freedom &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7259&quot;&gt;#7259&lt;/a&gt;
                implemented using the normal distribution (requested by Thomas Mang).
                Also much enhanced accuracy for large degrees of freedom and/or large
                non-centrality parameters by switching to use the Students t distribution
                (or Normal distribution for infinite degrees of freedom) centered
                at delta, when delta / (4 * v) &amp;lt; epsilon for the floating-point
                type in use. See &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7259&quot;&gt;#7259&lt;/a&gt;.
                It was also found that the incomplete beta was suffering from serious
                cancellation errors when degrees of freedom was very large. (That
                has now been fixed in our code, but any code based on Didonato and
                Morris's original papers (probably every implementation out there
                actually) will have the same issue).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed minor issues &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6517&quot;&gt;#6517&lt;/a&gt;,

            &lt;li&gt;
              &lt;div&gt;
                Included Voronoi diagram extensions.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Introduced new Segment concept.

            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed compilation issues.

            &lt;li&gt;
              &lt;div&gt;
                The data parameter to primitive transforms can now optionally have
                slots indexed by key.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Primitive transforms can now operatate on temporary expressions that
                are non-const qualified.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Add callable function object types for the free functions in &lt;code&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;iterator&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt; and also for some Boost.Range
                functions.

            &lt;/li&gt;

                now accepts an optional &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;Domain&lt;/span&gt;&lt;/code&gt;
                template parameter for specifying the target domain of the resulting

                &lt;em&gt;Deprecated Features&lt;/em&gt;: Deprecated
                features since boost 1.50 available only until boost 1.55. These
                deprecated features will be provided by default up to boost 1.52.
                If you don't want to include the deprecated features you could define
                BOOST_THREAD_DONT_PROVIDE_DEPRECATED_FEATURES_SINCE_V3_0_0. Since
                1.53 these features will not be included any more by default. Since
                this version, if you want to include the deprecated features yet
                you could define BOOST_THREAD_PROVIDE_DEPRECATED_FEATURES_SINCE_V3_0_0.
                These deprecated features will be only available until boost 1.55,
                that is you have yet 1 year to move to the new features.

                (Default value since Boost 1.53): There are some new features which
                share the same interface but with different behavior. These breaking
                features are provided by default when BOOST_THREAD_VERSION is 3,
                but the user can however choose the version 2 behavior by defining
                the corresponding macro. As for the deprecated features, these broken
                features will be only available until boost 1.55.

  &lt;div id=&quot;version_1_51_0.new_libraries&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;New Libraries&lt;/span&gt;&lt;/h3&gt;
    &lt;ul&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/context/&quot;&gt;Context&lt;/a&gt;:&lt;/span&gt;
  Context switching library,
          from Oliver Kowalke.
        &lt;/div&gt;
      &lt;/li&gt;
    &lt;/ul&gt;
  &lt;/div&gt;
  &lt;div id=&quot;version_1_51_0.updated_libraries&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;Updated Libraries&lt;/span&gt;&lt;/h3&gt;
    &lt;ul&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/algorithm/&quot;&gt;Algorithm&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;is_sorted_until&lt;/span&gt;&lt;/code&gt;
                ; now matches the c++11 standard behavior on ranges with duplicate
                values.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added range support for the rest of the search algorithms.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;unhex&lt;/span&gt;&lt;/code&gt; now uses Boost.Exception
                to signal bad input.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/asio/&quot;&gt;Asio&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed an incompatibility between &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ip&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;tcp&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;iostream&lt;/span&gt;&lt;/code&gt;
                and C++11 (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7162&quot;&gt;#7162&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Decorated GCC attribute names with underscores to prevent interaction
                with user-defined macros (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6415&quot;&gt;#6415&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added missing &lt;code&gt;&lt;span class=&quot;preprocessor&quot;&gt;#include&lt;/span&gt;
                &lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;cctype&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;, needed for some versions of
                MinGW.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed to use &lt;tt&gt;gcc&lt;/tt&gt;'s atomic builtins on ARM CPUs,
                when available (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7140&quot;&gt;#7140&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed strand destruction to be a no-op, to allow strand objects
                to be destroyed after their associated &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;io_service&lt;/span&gt;&lt;/code&gt;
                has been destroyed.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added support for some newer versions of glibc which provide the
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;epoll_create1&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
                function but always fail with &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ENOSYS&lt;/span&gt;&lt;/code&gt;
                (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7012&quot;&gt;#7012&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed the SSL implementation to throw an exception if SSL engine
                initialisation fails (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6303&quot;&gt;#6303&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed another regression in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;buffered_write_stream&lt;/span&gt;&lt;/code&gt;
                (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6310&quot;&gt;#6310&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Implemented various minor performance improvements, primarily targeted
                at Linux x86 and x86-64 platforms.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/config/&quot;&gt;Config&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Deprecated a whole bunch of macros that were c++11 specific, but
                not named to show that they were c++11 specific. Made new macros
                with better names, and paired the old macros with the new ones. Updated
                the documentation to list the deprecated macros.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/chrono/&quot;&gt;Chrono&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6918&quot;&gt;#6918&lt;/a&gt;
                Boost Chrono compilation failure on HP uX due to undefined pthread_getcpuclockid.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6241&quot;&gt;#6241&lt;/a&gt;
                boost::chrono compilation problems without std::wstring support.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;

                &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6987&quot;&gt;#6987&lt;/a&gt;
                Documentation &amp;amp; C++11.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;

                &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7041&quot;&gt;#7041&lt;/a&gt;
                time_point.hpp depends on Boost.System.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;

                &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7042&quot;&gt;#7042&lt;/a&gt;
                Avoiding time_point and duration dependency on time.h and CLOCK_REALTIME.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;

                &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7058&quot;&gt;#7058&lt;/a&gt;
                Make it work when BOOST_NO_EXCEPTIONS is defined.

                Misspellings in clock_string&amp;lt;thread_clock&amp;gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7081&quot;&gt;#7081&lt;/a&gt;
                WinError.h capitalization in boost/detail/win/basic_types.hpp.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/geometry/&quot;&gt;Geometry&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                points accessed through a pointer (e.g. in a linestring) should now
                be specialized without the pointer. In previous versions a type
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;my_point&lt;/span&gt;&lt;/code&gt; used like
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;linestring&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;my_point&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;*&amp;gt;&lt;/span&gt;&lt;/code&gt;
                had to be specalized like: &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;template&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt; &lt;span class=&quot;keyword&quot;&gt;struct&lt;/span&gt;
                &lt;span class=&quot;identifier&quot;&gt;tag&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;my_point&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;*&amp;gt;&lt;/span&gt;&lt;/code&gt;.
                Now the library itself removes the pointer before calling the traits
                class, so now it should be like: &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;template&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt; &lt;span class=&quot;keyword&quot;&gt;struct&lt;/span&gt;
                &lt;span class=&quot;identifier&quot;&gt;tag&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;my_point&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                intersection was sometimes wrong for integer points, fixed
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                documentation, order of parameters in simplify was wrong, fixed
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7030&quot;&gt;7030&lt;/a&gt;
                spherical distance, fixed (by patch of Karsten Ahnert)
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;

          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/graph/&quot;&gt;Graph&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Refactored support for internal and bundled properties in Boost.Graph-provided
                graph types, and cleaned up named parameter functionality:
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Enabled old-style (non-bundled) internal properties in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;compressed_sparse_row_graph&lt;/span&gt;&lt;/code&gt;.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Bundled properties should work correctly for all graph types
                      and adaptors.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;

              &lt;div&gt;

          - Fixes a bug when compiled using a C++11 compiler, but with a C++03 allocator.
          When inserting elements, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;allocator_traits&lt;/span&gt;&lt;/code&gt;
          detects that the node can be constructed using an accidental implicit conversion
          which causes several problems.

  A collection of
            useful generic algorithms, from Marshall Clow. This includes several
            different searching algorithms, as well as most of the new algorithms
            from the C++11 standard library

  Overload
            different functions into a single function object, from Lorenzo Caminiti.

  Program
            functions locally, within other functions, directly within the scope
            where they are needed, from Lorenzo Caminiti.
          &lt;/div&gt;

  Wrap
            types within round parenthesis so they can always be passed as macro
            parameters, from Lorenzo Caminiti.
          &lt;/div&gt;

              &lt;li&gt;

                  backend to do lazy registration for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;EPOLLOUT&lt;/span&gt;&lt;/code&gt;
                  events.

              &lt;li&gt;
                &lt;div&gt;
                  Fixed the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;epoll_reactor&lt;/span&gt;&lt;/code&gt;
                  handling of out-of-band data, which was broken by an incomplete
                  fix in the last release.
                &lt;/div&gt;
              &lt;/li&gt;
              &lt;li&gt;
                &lt;div&gt;
                  Changed Asio's SSL wrapper to respect OpenSSL's &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;OPENSSL_NO_ENGINE&lt;/span&gt;&lt;/code&gt;
                  feature test &lt;code&gt;&lt;span class=&quot;preprocessor&quot;&gt;#define&lt;/span&gt;&lt;/code&gt;

              &lt;li&gt;
                &lt;div&gt;

                  with Windows compilers that support C++11 move semantics (such
                  as &lt;tt&gt;g++&lt;/tt&gt;).
                &lt;/div&gt;
              &lt;/li&gt;
              &lt;li&gt;
                &lt;div&gt;

              &lt;/li&gt;
              &lt;li&gt;
                &lt;div&gt;
                  Added support for &lt;tt&gt;g++&lt;/tt&gt; 4.7 when compiling in
                  C++11 mode (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6620&quot;&gt;#6620&lt;/a&gt;).
                &lt;/div&gt;
              &lt;/li&gt;
              &lt;li&gt;
                &lt;div&gt;
                  Fixed a problem where &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;signal_set&lt;/span&gt;&lt;/code&gt;

                  the Version 2 behavior, but with corrections so that complex replacements

                &lt;div&gt;
                  Promoted math constants to be 1st class citizens, including convenient
                  access to the most widely used built-in float, double, long double
                  via three namespaces.
                &lt;/div&gt;

              &lt;li&gt;
                &lt;div&gt;
                  Added the Owen's T function and Skew Normal distribution written
                  by Benjamin Sobotta.
                &lt;/div&gt;
              &lt;/li&gt;
              &lt;li&gt;
                &lt;div&gt;
                  Added Hankel functions.
                &lt;/div&gt;
              &lt;/li&gt;
              &lt;li&gt;
                &lt;div&gt;
                  Corrected issue &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6627&quot;&gt;#6627
                  nonfinite_num_put formatting of 0.0 is incorrect&lt;/a&gt; based
                  on a patch submitted by K R Walker.
                &lt;/div&gt;
              &lt;/li&gt;
              &lt;li&gt;
                &lt;div&gt;
                  Changed constant initialization mechanism so that it is thread
                  safe even for user-defined types, also so that user defined types
                  get the full precision of the constant, even when &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;long&lt;/span&gt; &lt;span class=&quot;keyword&quot;&gt;double&lt;/span&gt;&lt;/code&gt;
                  does not. So for example 128-bit rational approximations will work
                  with UDT's and do the right thing, even though &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;long&lt;/span&gt;
                  &lt;span class=&quot;keyword&quot;&gt;double&lt;/span&gt;&lt;/code&gt; may be only 64 or
                  80 bits.
                &lt;/div&gt;
              &lt;/li&gt;
              &lt;li&gt;
                &lt;div&gt;
                  Fixed issue in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;bessel_jy&lt;/span&gt;&lt;/code&gt;
                  which causes Y[sub 8.5](4[pi]) to yield a NaN.
                &lt;/div&gt;

  &lt;div id=&quot;version_1_49_0.new_libraries&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;New Libraries&lt;/span&gt;&lt;/h3&gt;
    &lt;ul&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/heap/index.html&quot;&gt;Heap&lt;/a&gt;:&lt;/span&gt;
  Priority queue data
          structures, from Tim Blechmann.
        &lt;/div&gt;
      &lt;/li&gt;
    &lt;/ul&gt;
  &lt;/div&gt;
  &lt;div id=&quot;version_1_49_0.updated_libraries&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;Updated Libraries&lt;/span&gt;&lt;/h3&gt;
    &lt;ul&gt;
      &lt;li&gt;
        &lt;div&gt;
          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/asio&quot;&gt;Asio&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added a new class template &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;basic_waitable_timer&lt;/span&gt;&lt;/code&gt;
                based around the C++11 clock type requirements. It may be used with
                the clocks from the C++11 &lt;code&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;chrono&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;
                library facility or, if those are not available, Boost.Chrono. The
                typedefs &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;high_resolution_timer&lt;/span&gt;&lt;/code&gt;,
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;steady_timer&lt;/span&gt;&lt;/code&gt; and
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;system_timer&lt;/span&gt;&lt;/code&gt; may
                be used to create timer objects for the standard clock types.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added a new &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;windows&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;object_handle&lt;/span&gt;&lt;/code&gt;
                class for performing waits on Windows kernel objects. Thanks go to
                Boris Schaeling for contributing substantially to the development
                of this feature.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                On Linux, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;connect&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; can return EAGAIN in certain circumstances.
                Remapped this to another error so that it doesn't look like a non-blocking
                operation (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6048&quot;&gt;#6048&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed a compile error on NetBSD (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6098&quot;&gt;#6098&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed deadlock on Mac OS X (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6275&quot;&gt;#6275&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed a regression in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;buffered_write_stream&lt;/span&gt;&lt;/code&gt;
                (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6310&quot;&gt;#6310&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed a non-paged pool &amp;quot;leak&amp;quot; on Windows when an &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;io_service&lt;/span&gt;&lt;/code&gt; is repeatedly run without
                anything to do (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6321&quot;&gt;#6321&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Reverted earlier change to allow some speculative operations to be
                performed without holding the lock, as it introduced a race condition
                in some multithreaded scenarios.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed a bug where the second buffer in an array of two buffers may
                be ignored if the first buffer is empty.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;

                Locale codecvt_facet not thread safe on Windows. Move Windows, Mac
                OS X, locale and codecvt facet back to namespace scope. POSIX except
                OS X uses local static initialization (IE lazy) to ensure exceptions
                are catchable if environmental variables are misconfigured and to
                avoid use of locale(&amp;quot;&amp;quot;) if not actually used.

                by cleaning up test suite path_test.cpp code even though the ticket
                itself was not a defect, and clarifying docs; iteration over a path

                On compilers without rvalue references, the containers are no longer
                movable by default, as move emulation was causing some odd quirks

                to make them movable - Boost.Move is still used for elements regardless.

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Implemented various performance improvements, including:
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Using thread-local operation queues in single-threaded use
                      cases (i.e. when &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;concurrency_hint&lt;/span&gt;&lt;/code&gt;
                      is 1) to eliminate a lock/unlock pair.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Allowing some &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;epoll_reactor&lt;/span&gt;&lt;/code&gt;
                      speculative operations to be performed without holding the
                      lock.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Improving locality of reference by performing an &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;epoll_reactor&lt;/span&gt;&lt;/code&gt;'s I/O operation
                      immediately before the corresponding handler is called. Also
                      improves scalability across CPUs.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Specialising asynchronous read and write operations for buffer
                      sequences that are arrays (&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;array&lt;/span&gt;&lt;/code&gt;
                      or &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;std&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;array&lt;/span&gt;&lt;/code&gt;) of exactly two buffers.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed compile error in regex overload of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;async_read_until&lt;/span&gt;&lt;/code&gt;
                (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5688&quot;&gt;#5688&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed Windows-specific compile error by explicitly specifying the
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;signal&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
                function from the global namespace (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5722&quot;&gt;#5722&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;deadline_timer&lt;/span&gt;&lt;/code&gt;
                implementation to not read clock unless the timer heap is non-empty.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed SSL buffer sizes to be large enough to hold a complete TLS
                record (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5854&quot;&gt;#5854&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed synchronous &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;null_buffers&lt;/span&gt;&lt;/code&gt;
                operations so that they obey the user's non-blocking setting (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5756&quot;&gt;#5756&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed to set &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;fd_set&lt;/span&gt;&lt;/code&gt;
                size at runtime when using Windows.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Disabled MSVC warning due to const qualifier being applied to function
                type.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed crash that occurs when using Intel C++ compiler (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5763&quot;&gt;#5763&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed OpenSSL initialisation to support all available algorithms.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed SSL error mapping when session is gracefully shut down.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added some latency test programs.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Clarified that a read operation ends when the buffer is full (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5999&quot;&gt;#5999&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed exception safety issue in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;epoll_reactor&lt;/span&gt;&lt;/code&gt;
                initialisation (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6006&quot;&gt;#6006&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Made number of strand implementations configurable via &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_ASIO_STRAND_IMPLEMENTATIONS&lt;/span&gt;&lt;/code&gt;
                macro.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added support for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_ASIO_ENABLE_SEQUENTIAL_STRAND_ALLOCATION&lt;/span&gt;&lt;/code&gt;
                flag which switches strand allocation to use a round-robin approach
                rather than hashing.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed potential strand starvation issue that can occur when &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;strand&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;post&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
                is used.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;

                &lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/5979&quot;&gt;#5979&lt;/a&gt;
                Added chrono rounding utilities as defined by Howard Hinnant &lt;a href=&quot;http://home.roadrunner.com/~hinnant/duration_io/chrono_util.html&quot;&gt;here&lt;/a&gt;.
              &lt;/div&gt;

                &lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/5978&quot;&gt;#5978&lt;/a&gt;
                Add BOOST_CHRONO_HAS_PROCESS_CLOCKS to know if process clocks are
                available.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;

                &lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/5998&quot;&gt;#5998&lt;/a&gt;
                Make possible to disable hybrid error handling.
              &lt;/div&gt;
            &lt;/li&gt;

                &lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/5906&quot;&gt;#5906&lt;/a&gt;

            &lt;li&gt;
              &lt;div&gt;
                Fixed some bugs.

                  &lt;li&gt;
                    &lt;div&gt;
                      Robustness issue, in some circumstances the union failed to
                      output. Fixed.
                    &lt;/div&gt;

                      Robustness issue, in some circumstances the calculated intersection
                      point was outside the segment. Fixed.

                      Concept issue, cartesian intersect didn't understand segments
                      other than the provided one. Fixed.

            &lt;li&gt;
              &lt;div&gt;
                Improvements on algorithms:
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Checking self-intersections is now not done automatically,
                      this can blast performance.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Besides that, checking self-intersections is made faster.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Intersections now avoid outputting duplicate points. So they
                      output the minimal set.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Additional algorithms:
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      covered_by: within is defined as &amp;quot;within, not on boundary&amp;quot;.
                      covered_by is &amp;quot;within or on boundary&amp;quot;
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Additional functionality:
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      within: strategies can now be specified for within&amp;lt;point,
                      box&amp;gt; and within&amp;lt;box, box&amp;gt;
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      convert: a much broader range of conversions is supported
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      assign: idem, (currently partly) synonym for convert (but reversed
                      arguments)
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;
                Additional coordinate types:

                  &lt;li&gt;
                    &lt;div&gt;
                      Basic support for Boost.Rational
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;

            &lt;li&gt;
              &lt;div&gt;
                Changed edge_descriptor type for reverse_graph to a new data type
                to avoid ambiguities with the edge_descriptor of the underlying graph.
              &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;
                Added support to customize offset_ptr and allow creating custom managed
                segments that might be shared between 32 and 64 bit processes.
              &lt;/div&gt;

                Shared memory in windows has again filesystem lifetime: kernel bootstamp
                and WMI use to get a reliable timestamp was causing a lot of trouble.

                Added code to work with Inf and NaN values on any platform (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5689&quot;&gt;#5689&lt;/a&gt;).

                New Quickbook documentation (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5723&quot;&gt;#5723&lt;/a&gt;).

            &lt;li&gt;
              &lt;div&gt;
                Better performance and less memory usage for many combinations of
                Source and Target types.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Better performance for C locale.
              &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;
                Added new series evaluation methods to the cyclic Bessel I, J, K
                and Y functions. Also taken great care to avoid spurious over and
                underflow of these functions. Fixes issue &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5560&quot;&gt;#5560&lt;/a&gt;.
              &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;
                Added an example of using Inverse Chi-Squared distribution for Bayesian
                statistics, provided by Thomas Mang.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added tests to use improved version of lexical_cast which handles
                C99 nonfinites without using global facets.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Corrected wrong out-of-bound uniform distribution CDF complement
                values &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5733&quot;&gt;#5733&lt;/a&gt;.

            &lt;li&gt;
              &lt;div&gt;
                Enabled long double support on OpenBSD (issue &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6014&quot;&gt;#6014&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed nextafter and related functions to behave in the same way
                as other implementations - so that nextafter(+INF, 0) is a finite
                value (issue &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5832&quot;&gt;#5832&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Changed tuple include configuration to fix issue when using in conjunction
                with Boost.Tr1 (issue &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5934&quot;&gt;#5934&lt;/a&gt;).
              &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;
                Changed class eps_tolerance to behave correctly when both ends of
                the range are zero (issue &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6001&quot;&gt;#6001&lt;/a&gt;).
              &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;
                Fixed missing include guards on prime.hpp (issue &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5927&quot;&gt;#5927&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;

                Rewrite of internal transition tables. There were a few bugs (failing
                recursivity in internal transition tables of sub-sub machines) and
                a missing feature (unused internal transition table of the main state
                machine).
              &lt;/div&gt;

                    &lt;div&gt;
                      Reverted favor_compile_time policy to Boost 1.46 state
                    &lt;/div&gt;

                  &lt;li&gt;
                    &lt;div&gt;
                      Fixed not working Flag_AND

                  &lt;li&gt;
                    &lt;div&gt;
                      Fixed rare bugs causing multiple processing of the same event
                      in a submachine whose transition table contains this event
                      and a base event of it.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      gcc warnings about unused variables
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;

            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Breaking change: the new internal transition table feature causes
                a minor breaking change. In a submachine, the &amp;quot;Fsm&amp;quot; template
                parameter for guards / actions of an internal table declared using
                internal_transition_table now is the submachine, not the higher-level
                state machine. Internal transitions declared using internal rows
                in the higher-level state machine keep their behavior (the &amp;quot;Fsm&amp;quot;
                parameter is the higher-level state machine). To sum up, the internal
                transition &amp;quot;Fsm&amp;quot; parameter is the closest state machine
                containing this transition.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;

                &lt;em&gt;Breaking Change:&lt;/em&gt; Reduce numbers
                of operator overloads by using rvalue references on compilers that
                support them. Any user code that defines additional operator overloads
                on Proto expressions could potentially be rendered ambiguous by this
                change. The solution is to use a grammar to disable Proto's operators
                that are made ambiguous by any user-defined operators.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;

                    &lt;div&gt;
                      Added members to all distributions: &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;param_type&lt;/span&gt;&lt;/code&gt;,
                      &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;param&lt;/span&gt;&lt;/code&gt;, stream

                    &lt;div&gt;
                      Allow distributions to be used directly with generators without

                      and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;lognormal_distribution&lt;/span&gt;&lt;/code&gt;.

                    &lt;div&gt;
                      Added a second parameter to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;gamma_distribution&lt;/span&gt;&lt;/code&gt;.

                    &lt;div&gt;
                      Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;seed_seq&lt;/span&gt;&lt;/code&gt;
                      and added the corresponding constructors and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;seed&lt;/span&gt;&lt;/code&gt; overloads the generators.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;generate_canonical&lt;/span&gt;&lt;/code&gt;.

                    &lt;div&gt;
                      Renamed the engine tempates. e.g. &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;mersenne_twister&lt;/span&gt;&lt;/code&gt;
                      becomes &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;mersenne_twister_engine&lt;/span&gt;&lt;/code&gt;.
                    &lt;/div&gt;

                    &lt;div&gt;
                      New engine adapter &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;independent_bits_engine&lt;/span&gt;&lt;/code&gt;.
                    &lt;/div&gt;

                    &lt;div&gt;
                      Added new predefined engine typedefs: &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;mt19937_64&lt;/span&gt;&lt;/code&gt;,
                      &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ranlux&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;[&lt;/span&gt;&lt;span class=&quot;number&quot;&gt;24&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;|&lt;/span&gt;&lt;span class=&quot;number&quot;&gt;48&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;][&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;_base&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;]&lt;/span&gt;&lt;/code&gt;,
                      &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;knuth_b&lt;/span&gt;&lt;/code&gt;.

                    &lt;div&gt;

                Bug fixes:

                      could assert because the modular arithmetic was not implemented
                      in all cases. &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;shuffle_output&lt;/span&gt;&lt;/code&gt;,
                      now called &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;shuffle_order_engine&lt;/span&gt;&lt;/code&gt;,
                      could cause integer overflow. These cases were not triggered
                      by any predefined engines.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;

                    &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;
                Backwards compatibility issues:
                &lt;ul&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      The seeding algorithms have changed. This was unavoidable for
                      compatibility with the standard. Not to mention that some of
                      the existing algorithms were weird and inconsistent.
                      &lt;ul&gt;
                        &lt;li&gt;
                          &lt;div&gt;
                            Seeding with an integer: The behaviour should be unchanged
                            for most generators except &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;lagged_fibonacci&lt;/span&gt;&lt;/code&gt;
                            and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;subtract_with_carry&lt;/span&gt;&lt;/code&gt;
                            (and thus &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ranlux&lt;/span&gt;&lt;/code&gt;).
                          &lt;/div&gt;
                        &lt;/li&gt;
                        &lt;li&gt;
                          &lt;div&gt;
                            Seeding a generator with another generator: This has
                            been enabled by making all all generators models of
                            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;SeedSeq&lt;/span&gt;&lt;/code&gt;.
                            Therefore, if you seed a Boost.Random generator with
                            a non Boost.Random generator, your code will no longer
                            compile. The algorithm has changed, so code using this
                            seeding method will yield different values.
                          &lt;/div&gt;
                        &lt;/li&gt;
                        &lt;li&gt;
                          &lt;div&gt;
                            Seeding a generator from a pair of iterators: This implicitly
                            assumed that the elements were 32-bit integers in some
                            places, but not everywhere. I've added this requirement
                            everywhere and updated the algorithms accordingly. The
                            behaviour of generators with a &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;value_type&lt;/span&gt;&lt;/code&gt;
                            no more than 32 bits should be unchanged.
                          &lt;/div&gt;
                        &lt;/li&gt;
                      &lt;/ul&gt;
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Renaming:
                      &lt;ul&gt;
                        &lt;li&gt;
                          &lt;div&gt;
                            Whenever a class was renamed, there is a wrapper with
                            the old name. There are also using declarations in namespace
                            boost for everything that was moved.
                          &lt;/div&gt;
                        &lt;/li&gt;

                          &lt;div&gt;
                            The names of a few accessors in the distributions changed.
                            Both the old and the new names are allowed.
                          &lt;/div&gt;
                        &lt;/li&gt;
                      &lt;/ul&gt;
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;geometric_distribution&lt;/span&gt;&lt;/code&gt;
                      and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;lognormal_distribution&lt;/span&gt;&lt;/code&gt;:
                      The behaviour is different at runtime. &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;geometric_distribution&lt;/span&gt;&lt;/code&gt;
                      and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;lognormal_distribution&lt;/span&gt;&lt;/code&gt; provide
                      the old behaviour, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;random&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;geometric_distribution&lt;/span&gt;&lt;/code&gt;
                      and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;random&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;lognormal_distribution&lt;/span&gt;&lt;/code&gt; provide
                      the new behaviour.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Streaming: gamma_distribution has a new parameter, thus text
                      saved with the old version will not readable by the new version.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;variate_generator&lt;/span&gt;&lt;/code&gt;
                      is now a simple pass through wrapper. Code that assumes that
                      it will adjust the generator's result type to match the distribution
                      will no longer work. This is not an issue with any of the distributions
                      provided by Boost.Random.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      Return types: The &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;result_types&lt;/span&gt;&lt;/code&gt;
                      of some generators have changed slightly. Some signed types
                      have changed to unsigned to match the standard.
                    &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;li&gt;
                    &lt;div&gt;
                      &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;has_fixed_range&lt;/span&gt;&lt;/code&gt;:
                      This is now always false, as it doesn't appear to be very useful
                      and is excessively cumbersome. Anything that was accessing
                      &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;const_min&lt;/span&gt;&lt;/code&gt; and
                      &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;const_max&lt;/span&gt;&lt;/code&gt; without
                      first checking &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;has_fixed_range&lt;/span&gt;&lt;/code&gt;
                      was incorrect to begin with.
                    &lt;/div&gt;
                  &lt;/li&gt;
                &lt;/ul&gt;
              &lt;/div&gt;
            &lt;/li&gt;

              &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;EV_ONESHOT&lt;/span&gt;&lt;/code&gt; seems to
              cause problems on some versions of Mac OS X, with the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;io_service&lt;/span&gt;&lt;/code&gt; destructor getting stuck
              inside the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;close&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
              system call. Changed the kqueue backend to use &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;EV_CLEAR&lt;/span&gt;&lt;/code&gt;
              instead (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5021&quot;&gt;#5021&lt;/a&gt;).

          &lt;li&gt;
            &lt;div&gt;
              Fixed compile failures with some versions of &lt;tt&gt;g++&lt;/tt&gt;
              due to the use of anonymous enums (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4883&quot;&gt;#4883&lt;/a&gt;).
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Fixed a bug on kqueue-based platforms, where some system calls that
              repeatedly fail with &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;EWOULDBLOCK&lt;/span&gt;&lt;/code&gt;
              are not correctly re-registered with kqueue.
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Changed &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;asio&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;streambuf&lt;/span&gt;&lt;/code&gt; to ensure that its internal
              pointers are updated correctly after the data has been modified using
              &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;std&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;streambuf&lt;/span&gt;&lt;/code&gt; member functions.
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Fixed a bug that prevented the linger socket option from working on
              platforms other than Windows.
            &lt;/div&gt;
          &lt;/li&gt;

        &lt;ul&gt;
          &lt;li&gt;
            &lt;div&gt;
              Added support for cbegin/cend (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4761&quot;&gt;#4761&lt;/a&gt;)

          &lt;li&gt;

              Fixed a problem on older Linux kernels (where epoll is used without

              after the program has been running for some time (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5045&quot;&gt;#5045&lt;/a&gt;).

              fixed warnings with self-assignment (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4918&quot;&gt;#4918&lt;/a&gt;)

          &lt;li&gt;
            &lt;div&gt;
              Verify, clarify, document that &lt;code&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;config&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;user&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;

            &lt;/div&gt;

          &lt;li&gt;
            &lt;div&gt;
              Replaced C-style &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;assert&lt;/span&gt;&lt;/code&gt;
              with &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_ASSERT&lt;/span&gt;&lt;/code&gt;.
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Undeprecated &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;unique_path&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;. Instead, add a note mentioning the
              workaround for lack of thread safety and possible change to cwd. &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;unique_path&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
              is just too convenient to deprecate!
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Cleared several GCC warnings.
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Changed V2 code to use &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_THROW_EXCEPTION&lt;/span&gt;&lt;/code&gt;.
            &lt;/div&gt;
          &lt;/li&gt;

              correctly.
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Add &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;symlink_option&lt;/span&gt;&lt;/code&gt;
              to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;recursive_directory_iterator&lt;/span&gt;&lt;/code&gt;,
              allowing control over recursion into directory symlinks. Note that
              the default is changed to not recurse into directory symlinks.
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Reference documentation cleanup, including fixing missing and broken
              links, and adding missing functions.
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Miscellaneous implementation code cleanup.
            &lt;/div&gt;

        &lt;ul&gt;
          &lt;li&gt;
            &lt;div&gt;
              vector copy constructor now copies sequence members in the same order
              on different platforms (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2823&quot;&gt;#2823&lt;/a&gt;)
            &lt;/div&gt;

        &lt;/div&gt;
        &lt;ul&gt;
          &lt;li&gt;
            &lt;div&gt;
              Fixed Graphviz output to work on Visual C++ 7.1.
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Replaced assert with &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_ASSERT&lt;/span&gt;&lt;/code&gt;.
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Changed to Boost.Filesystem v3.
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;

          &lt;li&gt;
            &lt;div&gt;
              Added Wald, Inverse Gaussian and geometric distributions.
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Added information about configuration macros.

          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Added support for mpreal as a real-numered type.

          &lt;li&gt;
            &lt;div&gt;
              Fixed a problem on kqueue-based platforms where a &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;deadline_timer&lt;/span&gt;&lt;/code&gt;
              may never fire if the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;io_service&lt;/span&gt;&lt;/code&gt;
              is running in a background thread (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4568&quot;&gt;#4568&lt;/a&gt;).
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Fixed a const-correctness issue that prevented valid uses of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;has_service&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt;
              from compiling (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4638&quot;&gt;#4638&lt;/a&gt;).
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Fixed MinGW cross-compilation (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4491&quot;&gt;#4491&lt;/a&gt;).
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Removed dependency on deprecated Boost.System functions (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4672&quot;&gt;#4672&lt;/a&gt;).
            &lt;/div&gt;

          &lt;li&gt;
            &lt;div&gt;
              Ensured &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;close&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;/&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;closesocket&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
              failures are correctly propagated (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4573&quot;&gt;#4573&lt;/a&gt;).
            &lt;/div&gt;

          &lt;li&gt;
            &lt;div&gt;
              Added a check for errors returned by &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;InitializeCriticalSectionAndSpinCount&lt;/span&gt;&lt;/code&gt;
              (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4574&quot;&gt;#4574&lt;/a&gt;).
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Added support for hardware flow control on QNX (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4625&quot;&gt;#4625&lt;/a&gt;).
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Always use &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;pselect&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; on HP-UX, if it is available (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4578&quot;&gt;#4578&lt;/a&gt;).
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Ensured handler arguments are passed as lvalues (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4744&quot;&gt;#4744&lt;/a&gt;).
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Fixed Windows build when thread support is disabled (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4680&quot;&gt;#4680&lt;/a&gt;).
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Fixed a Windows-specific problem where &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;deadline_timer&lt;/span&gt;&lt;/code&gt;
              objects with expiry times set more than 5 minutes in the future may
              never expire (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4745&quot;&gt;#4745&lt;/a&gt;).
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Fixed the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;resolver&lt;/span&gt;&lt;/code&gt;
              backend on BSD platforms so that an empty service name resolves to
              port number &lt;code&gt;&lt;span class=&quot;number&quot;&gt;0&lt;/span&gt;&lt;/code&gt;, as per the
              documentation (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4690&quot;&gt;#4690&lt;/a&gt;).
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Fixed read operations so that they do not accept buffer sequences of
              type &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;const_buffers_1&lt;/span&gt;&lt;/code&gt;
              (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4746&quot;&gt;#4746&lt;/a&gt;).
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Redefined &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;Protocol&lt;/span&gt;&lt;/code&gt;
              and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;id&lt;/span&gt;&lt;/code&gt; to avoid clashing
              with Objective-C++ keywords (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4191&quot;&gt;#4191&lt;/a&gt;).
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Fixed a &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;vector&lt;/span&gt;&lt;/code&gt; reallocation
              performance issue that can occur when there are many active &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;deadline_timer&lt;/span&gt;&lt;/code&gt; objects (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4780&quot;&gt;#4780&lt;/a&gt;).
            &lt;/div&gt;

          &lt;li&gt;
            &lt;div&gt;
              Fixed the kqueue backend so that it compiles on NetBSD (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4662&quot;&gt;#4662&lt;/a&gt;).
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Fixed the socket &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;io_control&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; implementation on 64-bit Mac OS X
              and BSD platforms (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4782&quot;&gt;#4782&lt;/a&gt;).
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Fixed a Windows-specific problem where failures from &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;accept&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
              are incorrectly treated as successes (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4859&quot;&gt;#4859&lt;/a&gt;).
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Deprecated the separate compilation header &lt;code&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;asio&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;impl&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;src&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;cpp&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;
              in favour of &lt;code&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;asio&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;impl&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;src&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt; (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4560&quot;&gt;#4560&lt;/a&gt;).

        &lt;ul&gt;
          &lt;li&gt;
            &lt;div&gt;
              Added new defect macros, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_NO_VARIADIC_MACROS&lt;/span&gt;&lt;/code&gt;
              and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_NO_NUMERIC_LIMITS_LOWEST&lt;/span&gt;&lt;/code&gt;.

        &lt;ul&gt;
          &lt;li&gt;
            &lt;div&gt;
              Fixed a hanging problem with &lt;a href=&quot;/libs/flyweight/doc/tutorial/configuration.html#intermodule_holder&quot;&gt;&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;intermodule_holder&lt;/span&gt;&lt;/code&gt;&lt;/a&gt; in Win32
              platforms related to a Boost.Interprocess issue described at ticket
              &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4606&quot;&gt;#4606&lt;/a&gt;.
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Removed an internal assertion incompatible with program termination
              via &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;std&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;exit&lt;/span&gt;&lt;/code&gt;.
            &lt;/div&gt;

        &lt;/div&gt;
        &lt;ul&gt;
          &lt;li&gt;
            &lt;div&gt;
              Fix ambiguitiy by making &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;auto_any&lt;/span&gt;&lt;/code&gt;
              constructor explicit.
            &lt;/div&gt;

          &lt;li&gt;
            &lt;div&gt;
              Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_FUSION_ADAPT_ADT&lt;/span&gt;&lt;/code&gt;,
              &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_FUSION_ADAPT_TPL_ADT&lt;/span&gt;&lt;/code&gt;,

          &lt;li&gt;
            &lt;div&gt;
              Added Stoer-Wagner min-cut algorithm contributed by Daniel Trebbien.

          &lt;li&gt;
            &lt;div&gt;
              Added implicit graph (implicit_graph) and A* (astar_maze) examples
              contributed by W. P. McNeill.
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Added bundled property support for graph properties.
            &lt;/div&gt;
          &lt;/li&gt;

          &lt;li&gt;
            &lt;div&gt;
              Added support for standard rvalue reference move semantics (tested
              on GCC 4.5 and VC10).
            &lt;/div&gt;
          &lt;/li&gt;

              does not guarantee it's completed when returns, since it is not portable.
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              FreeBSD and MacOS now use posix semaphores to implement named semaphores
              and mutex.
            &lt;/div&gt;

          &lt;li&gt;
            &lt;div&gt;
              Added inverse gamma distribution and inverse chi_square and scaled
              inverse chi_square.
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Added warnings about potential ambiguity with std random library in
              distribution and function names.
            &lt;/div&gt;
          &lt;/li&gt;
          &lt;li&gt;
            &lt;div&gt;
              Editorial revision of documentation, and added FAQ.

              &lt;div&gt;
                Correct miscellaneous documentation inaccuracies
              &lt;/div&gt;

          &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/asio/index.html&quot;&gt;Asio&lt;/a&gt;:&lt;/span&gt;
          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Reduced compile times. (Note that some programs may need to add additional
                &lt;code&gt;&lt;span class=&quot;preprocessor&quot;&gt;#include&lt;/span&gt;&lt;/code&gt;s, e.g.
                if the program uses &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;array&lt;/span&gt;&lt;/code&gt;
                but does not explicitly include &lt;code&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;array&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;.)
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Reduced the size of generated code.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Refactored &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;deadline_timer&lt;/span&gt;&lt;/code&gt;
                implementation to improve performance.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Improved multiprocessor scalability on Windows by using a dedicated
                hidden thread to wait for timers.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Improved performance of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;asio&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;streambuf&lt;/span&gt;&lt;/code&gt;
                with &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;async_read&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
                and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;async_read_until&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;. These read operations now use
                the existing capacity of the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;streambuf&lt;/span&gt;&lt;/code&gt;
                when reading, rather than limiting the read to 512 bytes.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added optional separate compilation. To enable, add &lt;code&gt;&lt;span class=&quot;preprocessor&quot;&gt;#include&lt;/span&gt; &lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;asio&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;impl&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;src&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;cpp&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;
                to one source file in a program, then build the program with &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_ASIO_SEPARATE_COMPILATION&lt;/span&gt;&lt;/code&gt;
                defined in the project/compiler settings. Alternatively, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_ASIO_DYN_LINK&lt;/span&gt;&lt;/code&gt; may be defined
                to build a separately-compiled Asio as part of a shared library.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added new macro &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_ASIO_DISABLE_FENCED_BLOCK&lt;/span&gt;&lt;/code&gt;
                to permit the disabling of memory fences around completion handlers,
                even if thread support is enabled.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Reworked timeout examples to better illustrate typical use cases.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Ensured that handler arguments are passed as &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;const&lt;/span&gt;&lt;/code&gt;
                types.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed incorrect parameter order in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;null_buffers&lt;/span&gt;&lt;/code&gt;
                variant of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;async_send_to&lt;/span&gt;&lt;/code&gt;
                (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4170&quot;&gt;#4170&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Ensured &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;unsigned&lt;/span&gt; &lt;span class=&quot;keyword&quot;&gt;char&lt;/span&gt;&lt;/code&gt;
                is used with &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;isdigit&lt;/span&gt;&lt;/code&gt;
                in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;getaddrinfo&lt;/span&gt;&lt;/code&gt; emulation
                (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4201&quot;&gt;#4201&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed handling of very small but non-zero timeouts (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4205&quot;&gt;#4205&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed crash that occurred when an empty buffer sequence was passed
                to a composed read or write operation.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added missing &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;operator&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;+&lt;/span&gt;&lt;/code&gt; overload in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;buffers_iterator&lt;/span&gt;&lt;/code&gt;
                (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4382&quot;&gt;#4382&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Implemented cancellation of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;null_buffers&lt;/span&gt;&lt;/code&gt;
                operations on Windows.
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;
      &lt;/li&gt;

            &lt;li&gt;
              &lt;div&gt;
                Added new defect macro, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_NO_COMPLETE_VALUE_INITIALIZATION&lt;/span&gt;&lt;/code&gt;.
              &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;
                Added new defect macro &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_NO_0X_HDR_TYPEINDEX&lt;/span&gt;&lt;/code&gt;,
                fixes issue &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4274&quot;&gt;#4274&lt;/a&gt;.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Added support for code visibility in GCC.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;

                This release contains both version 2 and version 3 of the library.
                Version 3 is a major upgrade that will break some existing user code,
                so version 2 is the default. Users are encouraged to migrate to version
                3. See '&lt;a href=&quot;/libs/filesystem/v2/doc/index.htm&quot;&gt;Version 2&lt;/a&gt;'
                and '&lt;a href=&quot;/libs/filesystem/v3/doc/index.htm&quot;&gt;Version 3&lt;/a&gt;'
                for more information.
              &lt;/div&gt;
            &lt;/li&gt;

                Remove out-of-date work-arounds for sun compilers, fixes &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4306&quot;&gt;#4306&lt;/a&gt;.

            &lt;li&gt;
              &lt;div&gt;
                Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;fusion&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;reverse_fold&lt;/span&gt;&lt;/code&gt;, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;fusion&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;iter_fold&lt;/span&gt;&lt;/code&gt;

            &lt;li&gt;
              &lt;div&gt;
                Option to prevent implicit casts when calling the hash function by
                defining the macro &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_HASH_NO_IMPLICIT_CASTS&lt;/span&gt;&lt;/code&gt;,
                which can avoid some subtle problems. This might be activated by
                default in a future version.
              &lt;/div&gt;
            &lt;/li&gt;

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Several fixes for file descriptors class, including a breaking change
                to the constructors and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;open&lt;/span&gt;&lt;/code&gt;
                methods for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;file_descriptor&lt;/span&gt;&lt;/code&gt;,
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;file_descriptor_source&lt;/span&gt;&lt;/code&gt;
                and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;file_descriptor_sink&lt;/span&gt;&lt;/code&gt;.

                documentation&lt;/a&gt; for details. The old methods are still available
                if you define &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_IOSTREAMS_USE_DEPRECATED&lt;/span&gt;&lt;/code&gt;

            &lt;li&gt;
              &lt;div&gt;
                Fix several issues with compression and decompression (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2318&quot;&gt;#2318&lt;/a&gt;,

                Thanks to Steven Watanabe for almost all these fixes. For more detail

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed incorrect range and support for Rayleigh distribution.
              &lt;/div&gt;
            &lt;/li&gt;

            &lt;li&gt;
              &lt;div&gt;
                Make &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;mpl&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;string&lt;/span&gt;&lt;/code&gt; work with &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;mpl&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;transform&lt;/span&gt;&lt;/code&gt;.

          &lt;ul&gt;
            &lt;li&gt;
              &lt;div&gt;
                Fixed a bug preventing the use of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;modify_key&lt;/span&gt;&lt;/code&gt;
                with rollback in &lt;a href=&quot;/libs/multi_index/doc/reference/ord_indices.html#modify_key&quot;&gt;ordered&lt;/a&gt;

                indices when &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;Modifier&lt;/span&gt;&lt;/code&gt;
                and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;Rollback&lt;/span&gt;&lt;/code&gt; are
                different types (ticket &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4130&quot;&gt;#4130&lt;/a&gt;).
              &lt;/div&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
        &lt;/div&gt;

            &lt;li&gt;
              &lt;div&gt;
                &lt;em&gt;Minor change in behavior:&lt;/em&gt; when using
                &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;proto&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;and_&lt;/span&gt;&lt;/code&gt; as a transform, apply &lt;em&gt;all&lt;/em&gt;
                transforms but only return the result of applying the last. See Proto's
                &lt;a href=&quot;/doc/html/proto/appendices.html#boost_proto.appendices.release_notes.boost_1_44&quot;&gt;Release

                no longer run objects that are already proto expressions through
                the expression domain's generator. See Proto's &lt;a href=&quot;/doc/html/proto/appendices.html#boost_proto.appendices.release_notes.boost_1_44&quot;&gt;Release

            &lt;li&gt;
              &lt;div&gt;
                &lt;em&gt;Minor change in behavior:&lt;/em&gt; Proto
                uses &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;proto&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;basic_expr&lt;/span&gt;&lt;/code&gt; instead of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;proto&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;expr&lt;/span&gt;&lt;/code&gt; when possible for better compile
                times. See Proto's &lt;a href=&quot;/doc/html/proto/appendices.html#boost_proto.appendices.release_notes.boost_1_44&quot;&gt;Release
                Notes&lt;/a&gt; for details.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Add support for sub-domains.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Introduce per-domain &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;as_expr&lt;/span&gt;&lt;/code&gt;
                and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;as_child&lt;/span&gt;&lt;/code&gt; customization
                points to allow for domain-specific customization of variable capture
                behavior.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                The &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;proto&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;_default&lt;/span&gt;&lt;/code&gt; transform is also a grammar
                that matches the expressions the transform knows how to handle.
              &lt;/div&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div&gt;
                Add &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;proto&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;_void&lt;/span&gt;&lt;/code&gt;, a no-op primitive transform

                to the C++0x FCD. This change may cause compile errors some user
                code; the fix is add &amp;quot;()&amp;quot; to references to system_category
                and generic_category, so that they become function calls.

            Range-based version of the full STL iterator based algorithms.
          &lt;/li&gt;
          &lt;li&gt;
            Range adaptors which can be combined with range-based algorithms for
            unprecedented expressiveness and efficiency.
          &lt;/li&gt;
          &lt;li&gt;
            New functions: irange, istream_range, join, combine.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
    &lt;/ul&gt;
  &lt;/div&gt;
  &lt;div id=&quot;version_1_43_0.updated_libraries&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;Updated Libraries&lt;/span&gt;&lt;/h3&gt;
    &lt;ul&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/accumulators/index.html&quot;&gt;Accumulators&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Avoid premature template evaluation in operator overload return types.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/array/index.html&quot;&gt;Array&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Added support for SunCC compiler.
          &lt;/li&gt;
          &lt;li&gt;
            Added 'fill' member function.
          &lt;/li&gt;
          &lt;li&gt;
            Changed exception code to use boost::throw_exception.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/asio/index.html&quot;&gt;Asio&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Improved performance.
          &lt;/li&gt;
          &lt;li&gt;
            Reduced compile times.
          &lt;/li&gt;
          &lt;li&gt;
            Reduced the size of generated code.
          &lt;/li&gt;
          &lt;li&gt;
            Extended the guarantee that background threads don't call user code to
            all asynchronous operations (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3923&quot;&gt;#3923&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Changed to use edge-triggered epoll on Linux.
          &lt;/li&gt;
          &lt;li&gt;
            Changed to use &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;timerfd&lt;/span&gt;&lt;/code&gt;
            for dispatching timers on Linux, when available.
          &lt;/li&gt;
          &lt;li&gt;
            Changed to use one-shot notifications with kqueue on Mac OS X and BSD
            platforms.
          &lt;/li&gt;
          &lt;li&gt;
            Added a bitmask type &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ip&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;resolver_query_base&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;flags&lt;/span&gt;&lt;/code&gt;
            as per the TR2 proposal. This type prevents implicit conversion from
            &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;int&lt;/span&gt;&lt;/code&gt; to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;flags&lt;/span&gt;&lt;/code&gt;,
            allowing the compiler to catch cases where users incorrectly pass a numeric
            port number as the service name.
          &lt;/li&gt;
          &lt;li&gt;
            Added &lt;code&gt;&lt;span class=&quot;preprocessor&quot;&gt;#define&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;NOMINMAX&lt;/span&gt;&lt;/code&gt;
            for all Windows compilers. Users can define &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_ASIO_NO_NOMINMAX&lt;/span&gt;&lt;/code&gt;
            to suppress this definition (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3901&quot;&gt;#3901&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Fixed a bug where 0-byte asynchronous reads were incorrectly passing
            an &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;error&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;eof&lt;/span&gt;&lt;/code&gt; result to the completion handler
            (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/4023&quot;&gt;#4023&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Changed the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;io_control&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; member functions to always call &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ioctl&lt;/span&gt;&lt;/code&gt; on the underlying descriptor
            when modifying blocking mode (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3307&quot;&gt;#3307&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Changed the resolver implementation to longer require the typedefs &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;InternetProtocol&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;resolver_query&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;InternetProtocol&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;resolver_iterator&lt;/span&gt;&lt;/code&gt;,
            as neither typedef is part of the documented &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;InternetProtocol&lt;/span&gt;&lt;/code&gt;
            requirements. The corresponding typedefs in the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ip&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;tcp&lt;/span&gt;&lt;/code&gt;,
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ip&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;udp&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ip&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;icmp&lt;/span&gt;&lt;/code&gt;
            classes have been deprecated.
          &lt;/li&gt;
          &lt;li&gt;
            Fixed out-of-band handling for reactors not based on &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;select&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;.
          &lt;/li&gt;
          &lt;li&gt;
            Added new &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_ASIO_DISABLE_THREADS&lt;/span&gt;&lt;/code&gt;
            macro that allows Asio's threading support to be independently disabled.
          &lt;/li&gt;
          &lt;li&gt;
            Minor documentation improvements.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/fusion/index.html&quot;&gt;Fusion&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Added new macros for adapting or defining custom types. See the &lt;a href=&quot;/libs/fusion/doc/html/fusion/change_log.html&quot;&gt;Changelog&lt;/a&gt;
            for details.

          &lt;li&gt;
            Minor fixes (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2505&quot;&gt;#2505&lt;/a&gt;,
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3839&quot;&gt;#3839&lt;/a&gt;,

          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/proto/index.html&quot;&gt;Proto&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Minor change in behavior: non-const expression self-assignment creates
            an assign node. See Proto's &lt;a href=&quot;/doc/html/proto/appendices.html#boost_proto.appendices.release_notes.boost_1_43&quot;&gt;Release
            Notes&lt;/a&gt; for details.
          &lt;/li&gt;
          &lt;li&gt;
            Minor change to recommended expression extension mechanism: use &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_PROTO_EXTENDS_USING_ASSIGN&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;.
            See Proto's &lt;a href=&quot;/doc/html/proto/appendices.html#boost_proto.appendices.release_notes.boost_1_43&quot;&gt;Release
            Notes&lt;/a&gt; for details.
          &lt;/li&gt;
          &lt;li&gt;
            Fix error in invocation of callable monomorphic function objects in Proto
            transforms.
          &lt;/li&gt;
          &lt;li&gt;
            Fix misc const correctness issues, work around fusion bug.
          &lt;/li&gt;
          &lt;li&gt;
            Add non-const function call overloads to proto terminals.
          &lt;/li&gt;
          &lt;li&gt;
            Add a default constructor to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;proto&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;literal&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt;.
          &lt;/li&gt;
          &lt;li&gt;
            Do not use deprecated config macros.
          &lt;/li&gt;
          &lt;li&gt;
            Add &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;proto&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;assert_matches&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
            function and friends to &lt;tt&gt;&amp;lt;boost/proto/debug.hpp&amp;gt;&lt;/tt&gt;.
          &lt;/li&gt;
          &lt;li&gt;
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;functional&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;make_expr&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt;
            and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;functional&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;unpack_expr&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt;
            return const-qualified rvalues.
          &lt;/li&gt;
          &lt;li&gt;
            Add documentation for Expr and Domain concepts.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;

        &lt;ul&gt;
          &lt;li&gt;
            Put the implementation of random_device in a compiled lib, and added
            Windows support.
          &lt;/li&gt;
          &lt;li&gt;
            Rewrote the documentation using Quickbook/Doxygen/Boostbook and brought
            it up to date.
          &lt;/li&gt;

          &lt;/li&gt;
          &lt;li&gt;
            Added fix for issue 2742
          &lt;/li&gt;
          &lt;li&gt;
            Optimizations to mutex locks and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;call_once&lt;/span&gt;&lt;/code&gt;

          &lt;li&gt;
            Fixed bug in basic_random_generator (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3971&quot;&gt;#3971&lt;/a&gt;).
          &lt;/li&gt;

        When cross-compiling to GNU targets, static libraries are properly created.
        Previously, using such libraries resulted in &lt;tt&gt;Archive has no index&lt;/tt&gt;
        error.
      &lt;/li&gt;
      &lt;li&gt;
        The naming of DLL and import libraries with gcc compiler on Windows, both
        mingw and cygwin, now matches default conventions of those environments.
        Previously, the naming scheme was the same as for other Windows compilers.

            Unicode escape characters.
          &lt;/li&gt;
          &lt;li&gt;
            Support the UTF-8 byte order mark.
          &lt;/li&gt;
          &lt;li&gt;
            Disallow &lt;code&gt;&lt;span class=&quot;special&quot;&gt;[&lt;/span&gt;&lt;/code&gt; in simple markup.
            Fixes some errors with mismatched punctuation.
          &lt;/li&gt;
          &lt;li&gt;
            Add a command line flag (&lt;code&gt;&lt;span class=&quot;special&quot;&gt;-&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;D&lt;/span&gt;&lt;/code&gt;) to define macros at the command
            line.
          &lt;/li&gt;
          &lt;li&gt;
            Improved post-processor output.
          &lt;/li&gt;
          &lt;li&gt;
            Check that &lt;code&gt;&lt;span class=&quot;special&quot;&gt;[&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;section&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;]&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;special&quot;&gt;[&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;endsect&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;]&lt;/span&gt;&lt;/code&gt;
            tags are balanced in templates.

        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/uuid/index.html&quot;&gt;Uuid&lt;/a&gt;:&lt;/span&gt;
  A universally unique
        identifier, from Andy Tompkins.
      &lt;/li&gt;
    &lt;/ul&gt;
  &lt;/div&gt;
  &lt;div id=&quot;version_1_42_0.updated_libraries&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;Updated Libraries&lt;/span&gt;&lt;/h3&gt;
    &lt;ul&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/asio/index.html&quot;&gt;Asio&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Added a new HTTP Server 4 example illustrating the use of stackless coroutines
            with Asio.
          &lt;/li&gt;
          &lt;li&gt;
            Changed handler allocation and invocation to use &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;addressof&lt;/span&gt;&lt;/code&gt;
            to get the address of handler objects, rather than applying &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;operator&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;amp;&lt;/span&gt;&lt;/code&gt;
            directly (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2977&quot;&gt;#2977&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Restricted MSVC buffer debugging workaround to 2008, as it causes a crash
            with 2010 beta 2 (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3796&quot;&gt;#3796&lt;/a&gt;,
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3822&quot;&gt;#3822&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Fixed a problem with the lifetime of handler memory, where Windows needs
            the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;OVERLAPPED&lt;/span&gt;&lt;/code&gt; structure
            to be valid until both the initiating function call has returned and
            the completion packet has been delivered.
          &lt;/li&gt;
          &lt;li&gt;
            Don't block signals while performing system calls, but instead restart
            the calls if they are interrupted.
          &lt;/li&gt;
          &lt;li&gt;
            Documented the guarantee made by strand objects with respect to order
            of handler invocation.
          &lt;/li&gt;
          &lt;li&gt;
            Changed strands to use a pool of implementations, to make copying of
            strands cheaper.
          &lt;/li&gt;
          &lt;li&gt;
            Ensured that kqueue support is enabled for BSD platforms (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3626&quot;&gt;#3626&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Added a &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost_&lt;/span&gt;&lt;/code&gt; prefix
            to the &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;extern&lt;/span&gt; &lt;span class=&quot;string&quot;&gt;&amp;quot;C&amp;quot;&lt;/span&gt;&lt;/code&gt;
            thread entry point function (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3809&quot;&gt;#3809&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            In &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;getaddrinfo&lt;/span&gt;&lt;/code&gt; emulation,
            only check the socket type (&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;SOCK_STREAM&lt;/span&gt;&lt;/code&gt;
            or &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;SOCK_DGRAM&lt;/span&gt;&lt;/code&gt;) if a service
            name has been specified. This should allow the emulation to work with
            raw sockets.
          &lt;/li&gt;
          &lt;li&gt;
            Added a workaround for some broken Windows firewalls that make a socket
            appear bound to 0.0.0.0 when it is in fact bound to 127.0.0.1.
          &lt;/li&gt;
          &lt;li&gt;
            Applied a fix for reported excessive CPU usage under Solaris (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3670&quot;&gt;#3670&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Added some support for platforms that use older compilers such as g++
            2.95 (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3743&quot;&gt;#3743&lt;/a&gt;).
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/circular_buffer/index.html&quot;&gt;Circular Buffer&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Added methods erase_begin(size_type) and erase_end(size_type) with constant
            complexity for such types of stored elements which do not need an explicit
            destruction e.g. int or double.
          &lt;/li&gt;
          &lt;li&gt;
            Similarly changed implementation of the clear() method and the destructor
            so their complexity is now constant for such types of stored elements
            which do not require an explicit destruction (the complexity for other
            types remains linear).
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/fusion/index.html&quot;&gt;Fusion&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            The accumulator is the first argument to the functor of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;fusion&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;fold&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;fusion&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;accumulate&lt;/span&gt;&lt;/code&gt;
            (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2355&quot;&gt;#2355&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Added support for associative iterators and views (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3473&quot;&gt;#3473&lt;/a&gt;).
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/graph/index.html&quot;&gt;Graph&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Removed old interface to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;compressed_sparse_row_graph&lt;/span&gt;&lt;/code&gt;,
            making new interface the default.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/integer/index.html&quot;&gt;Integer&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Reverted Trunk to release branch state (i.e. a &amp;quot;known good state&amp;quot;).
          &lt;/li&gt;
          &lt;li&gt;
            Fixed issues: &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/653&quot;&gt;653&lt;/a&gt;,
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3084&quot;&gt;3084&lt;/a&gt;,
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3177&quot;&gt;3177&lt;/a&gt;,
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3180&quot;&gt;3180&lt;/a&gt;,
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3548&quot;&gt;3568&lt;/a&gt;,
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3657&quot;&gt;3657&lt;/a&gt;,
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2134&quot;&gt;2134&lt;/a&gt;.
          &lt;/li&gt;
          &lt;li&gt;
            Added long long support to &lt;tt&gt;boost::static_log2&lt;/tt&gt;, &lt;tt&gt;boost::static_signed_min&lt;/tt&gt;,
            &lt;tt&gt;boost::static_signed_max&lt;/tt&gt;, &lt;tt&gt;boost::static_unsigned_min&lt;/tt&gt;&lt;tt&gt;boost::static_unsigned_max&lt;/tt&gt;,
            when available.
          &lt;/li&gt;
          &lt;li&gt;
            The argument type and the result type of &lt;tt&gt;boost::static_signed_min&lt;/tt&gt;
            etc are now typedef'd. Formerly, they were hardcoded as &lt;tt&gt;unsigned
            long&lt;/tt&gt; and &lt;tt&gt;int&lt;/tt&gt; respectively. Please, use the
            provided typedefs in new code (and update old code as soon as possible).
          &lt;/li&gt;

        &lt;ul&gt;
          &lt;li&gt;
            Information about option name added to a few exception classes and various
            clean ups in exception classes (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3423&quot;&gt;#3423&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Description wordwrapping in presense of default parameters fixed (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2613&quot;&gt;#2613&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Empty value in configuration file is now permitted (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1537&quot;&gt;#1537&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Quotes are no longer stripped from string values (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/850&quot;&gt;#850&lt;/a&gt;).

            Fix endless loop in case of long default arguments (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/689&quot;&gt;#689&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Fix compile warning caused by usage of boost::any (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2562&quot;&gt;#2562&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Fix memory bug in example/response_file.cpp (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3525&quot;&gt;#3525&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Most compilation warnings were fixed (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3608&quot;&gt;#3608&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Make column width for description text configurable. (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3703&quot;&gt;#3703&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Add general split function: split_unix() (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2561&quot;&gt;#2561&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Enable open config files from given file name (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3264&quot;&gt;#3264&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Additional flag for required options (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2982&quot;&gt;#2982&lt;/a&gt;).
          &lt;/li&gt;

            Enable case insensitive style for command line (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3498&quot;&gt;#3498&lt;/a&gt;).

        &lt;ul&gt;
          &lt;li&gt;
            Removed old header files (directly in the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;/code&gt; directory); they were deprecated since
            1.40, replaced by headers in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;property_map&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;/code&gt;.

        &lt;ul&gt;
          &lt;li&gt;
            Fix const correctness issues with &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;proto&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;flatten&lt;/span&gt;&lt;/code&gt;
            and friends (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3364&quot;&gt;#3364&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Accomodate recent change to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;fusion&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;fold&lt;/span&gt;&lt;/code&gt;,
            remove old support for Doxygen and pre-1.35 Fusion (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3553&quot;&gt;#3553&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            In binary operations, when one operand has a user-specified domain and
            the other has the default domain, the user-specified domain trumps.
          &lt;/li&gt;
          &lt;li&gt;
            Fix &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_PROTO_EXTENDS&lt;/span&gt;&lt;/code&gt;
            to work with elaborated types.
          &lt;/li&gt;
          &lt;li&gt;
            Work around EDG compiler bug with function types and cv-qualification.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;

        &lt;ul&gt;
          &lt;li&gt;
            Added support for Functors rather than strings as format expressions.
          &lt;/li&gt;
          &lt;li&gt;
            Improved error reporting when throwing exceptions to include better more
            relevant information.
          &lt;/li&gt;
          &lt;li&gt;
            Improved performance and reduced stack usage of recursive expressions.
          &lt;/li&gt;

          &lt;li&gt;
            Support instantiating the containers with incomplete value types.
          &lt;/li&gt;
          &lt;li&gt;
            Add &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;erase_return_void&lt;/span&gt;&lt;/code&gt;
            as a temporary workaround for the current &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;erase&lt;/span&gt;&lt;/code&gt;
            which can be inefficient because it has to find the next element to return
            an iterator (&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/3693&quot;&gt;#3693&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Add templated find overload for compatible keys.
          &lt;/li&gt;
          &lt;li&gt;
            Improved codegear compatibility.

        &lt;ul&gt;
          &lt;li&gt;
            The default format for time durations is now &amp;quot;&lt;code&gt;&lt;span class=&quot;special&quot;&gt;%-%&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;O&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;:%&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;M&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;:%&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;S&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;%&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;F&lt;/span&gt;&lt;/code&gt;&amp;quot; instead of &amp;quot;&lt;code&gt;&lt;span class=&quot;special&quot;&gt;%-%&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;H&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;:%&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;M&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;:%&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;S&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;%&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;F&lt;/span&gt;&lt;/code&gt;&amp;quot;
            that was used previously. In order to retain the old behavior, the format
            string has to be specified explicitly during the time IO facet construction

        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/iostreams/index.html&quot;&gt;Iostreams&lt;/a&gt;:&lt;/span&gt;
  Some old
        unreleased developments. There are still several open issues that should
        be fixed in the next version.
        &lt;ul&gt;
          &lt;li&gt;
            Add a grep filter (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1627&quot;&gt;#1627&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Support archives with multiple members (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1896&quot;&gt;#1896&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Make &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;tee&lt;/span&gt;&lt;/code&gt; work with input
            streams (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/791&quot;&gt;#791&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Improved filesystem interoperability.
          &lt;/li&gt;
          &lt;li&gt;
            Several warnings fixed or suppressed (including &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1618&quot;&gt;#1618&lt;/a&gt;,
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1875&quot;&gt;#1875&lt;/a&gt;,
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2779&quot;&gt;#2779&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Various other fixes (including &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1580&quot;&gt;#1580&lt;/a&gt;,
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1671&quot;&gt;#1671&lt;/a&gt;).
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/math/index.html&quot;&gt;Math&lt;/a&gt;:&lt;/span&gt;
  Substantially improved
        the performance of the incomplete gamma function and it's inverse: this enhances
        the performance of the gamma, poisson, chi-squared and non-central chi-squared
        distributions.
      &lt;/li&gt;

        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/multi_index/doc/index.html&quot;&gt;Multi-index Containers&lt;/a&gt;:&lt;/span&gt;
  Maintenance
        fixes. Consult the library &lt;a href=&quot;/libs/multi_index/doc/release_notes.html#boost_1_41&quot;&gt;release
        notes&lt;/a&gt; for further information.
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/proto/index.html&quot;&gt;Proto&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Clean up some MSVC warnings and errors in /Za (disable Microsoft extensions)
            mode.
          &lt;/li&gt;
          &lt;li&gt;
            Fixes for c++0x mode on various compilers.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/python/index.html&quot;&gt;Python&lt;/a&gt;:&lt;/span&gt;
  Boost.Python now
        supports Python 3 (Haoyu Bai's Google Summer of Code project, mentored by
        Stefan Seefeld).
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/regex/index.html&quot;&gt;Regex&lt;/a&gt;:&lt;/span&gt;
  Added support for
        many Perl 5.10 syntax elements including named sub-expressions, branch resets
        and recursive regular expressions.
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/spirit/index.html&quot;&gt;Spirit&lt;/a&gt;:&lt;/span&gt; This is the initial
        official release of the new Spirit V2.1, a completely new library for parsing,
        lexing, and output generation. Note: this release is not backwards compatible
        with earlier versions. Known issue: &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;qi&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;symbol&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;find&lt;/span&gt;&lt;/code&gt;
        will match a symbol that starts with the string you're searching for. This
        will be fixed in the next version.
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/system/index.html&quot;&gt;System&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Bug fix: (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3559&quot;&gt;#3559&lt;/a&gt;).
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/thread/index.html&quot;&gt;Thread&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Support for futures, promises and packaged tasks added
          &lt;/li&gt;
          &lt;li&gt;
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;thread_specific_ptr&lt;/span&gt;&lt;/code&gt; is now faster when
            there are lots of thread-specific objects
          &lt;/li&gt;
          &lt;li&gt;
            Some Boost.Thread facilities are now header-only
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/unordered/index.html&quot;&gt;Unordered&lt;/a&gt;:&lt;/span&gt;
  Major update:
        &lt;ul&gt;
          &lt;li&gt;
            Replaced a lot of the macro based implementation with a cleaner template
            based implementation.
          &lt;/li&gt;
          &lt;li&gt;
            Reduced memory use.
          &lt;/li&gt;
          &lt;li&gt;

        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/utility/index.html&quot;&gt;Utility&lt;/a&gt;:&lt;/span&gt;

        issue of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;value_initialized&lt;/span&gt;&lt;/code&gt;
        is fixed: Its &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;data&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
        member function and its conversion operator are replaced by overloads for
        const and non-const access (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2548&quot;&gt;#2548&lt;/a&gt;).

        &lt;ul&gt;
          &lt;li&gt;
            Fix infinite loop with some uses of &lt;tt&gt;\Q...\E&lt;/tt&gt; quotemeta
            (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3586&quot;&gt;#3586&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Eliminate unreachable code warnings on MSVC
          &lt;/li&gt;
          &lt;li&gt;
            Clean up some MSVC warnings and errors in /Za (&amp;quot;disable Microsoft
            extensions&amp;quot;) mode.
          &lt;/li&gt;
          &lt;li&gt;
            Fixes for c++0x mode on various compilers.

      A bug preventing &amp;quot;fat&amp;quot; 32-bit + 64-bit builds on OSX has been fixed.

    &lt;p&gt;
      The cmake version of boost has moved; the Boost.CMmake release will be separate
      and will lag the main release slightly, but will also be capable of producing
      patch releases as necessary.
    &lt;/p&gt;

        &lt;ul&gt;
          &lt;li&gt;
            More intuitive syntax and variable lookup for template calls (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1174&quot;&gt;#1174&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2034&quot;&gt;#2034&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2036&quot;&gt;#2036&lt;/a&gt;).

        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/accumulators/index.html&quot;&gt;Accumulators&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Works on GCC 4.4.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/asio/index.html&quot;&gt;Asio&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Added a new ping example to illustrate the use of ICMP sockets.
          &lt;/li&gt;
          &lt;li&gt;
            Changed the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;buffered&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;*&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;_stream&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt; templates to treat 0-byte reads
            and writes as no-ops, to comply with the documented type requirements
            for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;SyncReadStream&lt;/span&gt;&lt;/code&gt;,
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;AsyncReadStream&lt;/span&gt;&lt;/code&gt;, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;SyncWriteStream&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;AsyncWriteStream&lt;/span&gt;&lt;/code&gt;.
          &lt;/li&gt;
          &lt;li&gt;
            Changed some instances of the &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;throw&lt;/span&gt;&lt;/code&gt;
            keyword to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;throw_exception&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
            to allow Asio to be used when exception support is disabled. Note that
            the SSL wrappers still require exception support (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2754&quot;&gt;#2754&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Made Asio compatible with the OpenSSL 1.0 beta (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3256&quot;&gt;#3256&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Eliminated a redundant system call in the Solaris &lt;tt&gt;/dev/poll&lt;/tt&gt;
            backend.
          &lt;/li&gt;
          &lt;li&gt;
            Fixed a bug in resizing of the bucket array in the internal hash maps
            (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3095&quot;&gt;#3095&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Ensured correct propagation of the error code when a synchronous accept
            fails (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3216&quot;&gt;#3216&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Ensured correct propagation of the error code when a synchronous read
            or write on a Windows HANDLE fails.
          &lt;/li&gt;
          &lt;li&gt;
            Fixed failures reported when &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;_GLIBCXX_DEBUG&lt;/span&gt;&lt;/code&gt;
            is defined (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3098&quot;&gt;#3098&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Fixed custom memory allocation support for timers (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3107&quot;&gt;#3107&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Tidied up various warnings reported by g++ (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1341&quot;&gt;#1341&lt;/a&gt;,
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2618&quot;&gt;#2618&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Various documentation improvements, including more obvious hyperlinks
            to function overloads, header file information, examples for the handler
            type requirements, and adding enum values to the index (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3157&quot;&gt;#3157&lt;/a&gt;,
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2620&quot;&gt;#2620&lt;/a&gt;).

            Fixed bugs &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2785&quot;&gt;#2785&lt;/a&gt;,
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3285&quot;&gt;#3285&lt;/a&gt;.

            Workaround for conflict with Python headers (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3000&quot;&gt;#3000&lt;/a&gt;).
          &lt;/li&gt;

        &lt;ul&gt;
          &lt;li&gt;
            Optimize the use of small target objects.
          &lt;/li&gt;
          &lt;li&gt;
            Make Boost.Function compile under BOOST_NO_EXCEPTIONS (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2499&quot;&gt;#2499&lt;/a&gt;,

        &lt;ul&gt;
          &lt;li&gt;
            Merged in the &lt;a href=&quot;/libs/graph_parallel/doc/html/index.html&quot;&gt;Parallel
            Boost Graph Library&lt;/a&gt;, giving a full suite of graph algorithms
            and data structures for distributed-memory computers (such as clusters).
          &lt;/li&gt;
          &lt;li&gt;
            Updates to the interface of the compressed sparse row graph, including
            constructors from unsorted edge lists.
          &lt;/li&gt;
          &lt;li&gt;
            An implicit grid graph, saving memory over using the former generator.
          &lt;/li&gt;
          &lt;li&gt;
            New algorithms: Dijkstra's single-source shortest path algorithm without
            a separate color map and an algorithm to find maximal common subgraphs
            between two graphs.
          &lt;/li&gt;

          &lt;li&gt;
            Automatically configure the float functions using template metaprogramming
            instead of trying to configure every possibility manually.
          &lt;/li&gt;
        &lt;/ul&gt;

          &lt;li&gt;
            Windows shared memory is created in Shared Documents folder so that it
            can be shared between services and processes
          &lt;/li&gt;
          &lt;li&gt;
            Fixed bugs &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2967&quot;&gt;#2967&lt;/a&gt;,

        &lt;ul&gt;
          &lt;li&gt;
            Code cleanup in tree_algorithms.hpp and avl_tree_algorithms.hpp
          &lt;/li&gt;
          &lt;li&gt;
            Fixed bug &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3164&quot;&gt;#3164&lt;/a&gt;.

        &lt;ul&gt;
          &lt;li&gt;
            Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;mpl&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;char_&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;mpl&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;string&lt;/span&gt;&lt;/code&gt;
            for compile-time string manipulation, based on multichar literals (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2905&quot;&gt;#2905&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Updated &lt;a href=&quot;/libs/mpl/doc/refmanual.html&quot;&gt;MPL Reference Manual&lt;/a&gt;.
          &lt;/li&gt;
          &lt;li&gt;
            Bug fixes.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/program_options/index.html&quot;&gt;Program.Options&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Support for building with disabled exceptions (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2096&quot;&gt;#2096&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Unicode parser no longer drops original tokens (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2425&quot;&gt;#2425&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Fixed crash on user-inserted items in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;variables_map&lt;/span&gt;&lt;/code&gt;
            (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2782&quot;&gt;#2782&lt;/a&gt;).
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/property_map/index.html&quot;&gt;Property Map&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Moved property map code into a separate directory, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;property_map&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;/code&gt;. The old files exist and forward to
            the new ones; the previous files directly in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;/code&gt; will be removed in Boost 1.42.0.
          &lt;/li&gt;
          &lt;li&gt;
            Moved distributed property maps to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;graph&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;parallel&lt;/span&gt;&lt;/code&gt;
            namespace.
          &lt;/li&gt;
          &lt;li&gt;
            Added a property map based on a &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;shared_array&lt;/span&gt;&lt;/code&gt;,
            providing a simpler interface.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/proto/index.html&quot;&gt;Proto&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            PrimitiveTransforms have stricter conformance to ResultOf protocol. (Warning:
            some invalid code may break.)
          &lt;/li&gt;
          &lt;li&gt;
            Add a sensible default for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;proto&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;_default&lt;/span&gt;&lt;/code&gt;'s
            template parameter.
          &lt;/li&gt;
          &lt;li&gt;
            Improved default evaluation strategy for pointers to members.
          &lt;/li&gt;
          &lt;li&gt;
            GCC 3.4 portability fixes (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3021&quot;&gt;#3021&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Work around Visual C++'s non-std-compliant ciso646 macros.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/random/index.html&quot;&gt;Random&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Made the constructors of all the generators call the copy constructor
            when passed a non-const reference.
          &lt;/li&gt;
          &lt;li&gt;
            Changed seeding functions to accept any arithmetic type. As a side-effect,
            the exact signature of seed changed for some classes.
          &lt;/li&gt;
          &lt;li&gt;
            Major bug fixes in uniform_int.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/serialization/index.html&quot;&gt;Serialization&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Removed deprecated headers: &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;static_warning&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;/code&gt;,
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;state_saver&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;/code&gt;, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;smart_cast&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;/code&gt;,
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;pfto&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;/code&gt;. Use the the equivalent headers
            in the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;serialization&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;/code&gt;
            directory instead (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3062&quot;&gt;#3062&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;detail&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;archive_serializer_map&lt;/span&gt;&lt;/code&gt; should now be
            used instead of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;detail&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;archive_pointer_iserializer&lt;/span&gt;&lt;/code&gt;.
            For more details see &lt;a href=&quot;/doc/libs/1_40_0/libs/serialization/doc/release.html&quot;&gt;the
            library release notes&lt;/a&gt;.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/unordered/index.html&quot;&gt;Unordered&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Implement &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;emplace&lt;/span&gt;&lt;/code&gt; for
            all compilers, not just ones with rvalue references and variadic templates
            (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1978&quot;&gt;#1978&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Create less buckets by default.
          &lt;/li&gt;
          &lt;li&gt;
            Some minor tweaks for better compiler support (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2908&quot;&gt;#2908&lt;/a&gt;,
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3096&quot;&gt;#3096&lt;/a&gt;,
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3082&quot;&gt;#3082&lt;/a&gt;).
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/xpressive/index.html&quot;&gt;Xpressive&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Works on Visual C++ 10.0 (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3124&quot;&gt;#3124&lt;/a&gt;).
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
    &lt;/ul&gt;

    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;Build System&lt;/span&gt;&lt;/h3&gt;
    &lt;p&gt;
      The default naming of libraries in Unix-like environment now matches system
      conventions, and does not include various decorations. Naming of libraries
      on Cygwin was also fixed. Support for beta versions of Microsoft Visual Studio
      10 was added. With gcc, 64-bit compilation no longer requires that target architecture
      be specified.
    &lt;/p&gt;
  &lt;/div&gt;
  &lt;div id=&quot;version_1_40_0.updated_tools&quot;&gt;

          &lt;li&gt;
            Hide &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;INTERNAL&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;ONLY&lt;/span&gt;&lt;/code&gt;
            enums in doxygen documentation (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3242&quot;&gt;#3242&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Tweaked appearance of member classes/structs/unions in a class synopsis.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/tools/quickbook/index.html&quot;&gt;Quickbook&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Support python code snippets (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/3029&quot;&gt;#3029&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Add &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;teletype&lt;/span&gt;&lt;/code&gt; source mode
            (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1202&quot;&gt;#1202&lt;/a&gt;)
          &lt;/li&gt;

          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;

          &lt;li&gt;
            Intel 10.1 on Suse Linux on 64 bit Itanium.
          &lt;/li&gt;

            Intel 11.0 on Red Hat Enterprise Linux.
          &lt;/li&gt;
          &lt;li&gt;
            Intel 11.1 on Red Hat Enterprise Linux.
          &lt;/li&gt;
          &lt;li&gt;
            GCC 3.4.3, GCC 4.0.1, GCC 4.2.4, GCC 4.3.3 and GCC 4.4.0 on Red Hat Enterprise
            Linux.
          &lt;/li&gt;
          &lt;li&gt;
            GCC 4.3.3 and GCC 4.4.0 with C++0x extensions on Red Hat Enterprise Linux.
          &lt;/li&gt;
          &lt;li&gt;
            GCC 4.1.1, 4.2.1 on 64-bit Red Hat Enterprise Linux.

      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/asio/index.html&quot;&gt;Asio&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Implement automatic resizing of the bucket array in the internal hash
            maps. This is to improve performance for very large numbers of asynchronous
            operations and also to reduce memory usage for very small numbers. A
            new macro &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_ASIO_HASH_MAP_BUCKETS&lt;/span&gt;&lt;/code&gt;
            may be used to tweak the sizes used for the bucket arrays.
          &lt;/li&gt;
          &lt;li&gt;
            Add performance optimisation for the Windows IOCP backend for when no
            timers are used.
          &lt;/li&gt;
          &lt;li&gt;
            Prevent locale settings from affecting formatting of TCP and UDP endpoints
            (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2682&quot;&gt;#2682&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Fix a memory leak that occurred when an asynchronous SSL operation's
            completion handler threw an exception (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2910&quot;&gt;#2910&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Fix the implementation of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;io_control&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; so that it adheres to the documented
            type requirements for IoControlCommand (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2820&quot;&gt;#2820&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Fix incompatibility between Asio and ncurses.h (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2156&quot;&gt;#2156&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            On Windows, specifically handle the case when an overlapped &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ReadFile&lt;/span&gt;&lt;/code&gt; call fails with &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ERROR_MORE_DATA&lt;/span&gt;&lt;/code&gt;. This enables a hack
            where a &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;windows&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;stream_handle&lt;/span&gt;&lt;/code&gt; can be used with a message-oriented
            named pipe (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2936&quot;&gt;#2936&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Fix system call wrappers to always clear the error on success, as POSIX
            allows successful system calls to modify errno (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2953&quot;&gt;#2953&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Don't include termios.h if &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_ASIO_DISABLE_SERIAL_PORT&lt;/span&gt;&lt;/code&gt;
            is defined (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2917&quot;&gt;#2917&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Cleaned up some more MSVC level 4 warnings (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2828&quot;&gt;#2828&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Various documentation fixes (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2871&quot;&gt;#2871&lt;/a&gt;).
          &lt;/li&gt;

            The &lt;a href=&quot;/libs/flyweight/doc/tutorial/configuration.html#refcounted&quot;&gt;refcounted&lt;/a&gt;
            component was not thread-safe due to an incorrect implementation and
            could deadlock under heavy usage conditions. This problem has been corrected.

          &lt;li&gt;
            Eliminate shadow warnings on gcc for nested &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;FOREACH&lt;/span&gt;&lt;/code&gt;

        &lt;ul&gt;
          &lt;li&gt;
            Remove deprecated headers for hashing containers. Everything that was
            in them is included in &lt;code&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;functional&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hash&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;

            Fix bug where a function's &lt;code&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;purpose&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;
            wasn't displayed if it was just plain text.
          &lt;/li&gt;
          &lt;li&gt;
            Support the alt tag in &lt;code&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;headername&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;
            and &lt;code&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;macroname&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;. Use this if the header or macro
            name is different to the contents of the tag (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1977&quot;&gt;#1977&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Support links relative to the boost root in &lt;code&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;ulink&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;
            tags, using a custom url, see the &lt;a href=&quot;/doc/html/boostbook/together.html#boostbook.linking&quot;&gt;linking
            documentation&lt;/a&gt; for details (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1166&quot;&gt;#1166&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Avoid generating filenames that only differ in case for function, method
            and macro documentation.
          &lt;/li&gt;
          &lt;li&gt;
            Run the docbook chunker quietly, unless boostbook.verbose is set. This
            parameter might be used in other places in future releases.
          &lt;/li&gt;
          &lt;li&gt;
            Make the 1.1 DTD available.
          &lt;/li&gt;
          &lt;li&gt;
            Fill in some missing reference documentation (partially fixes &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2153&quot;&gt;#2153&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Changes to doxygen integration:
            &lt;ul&gt;
              &lt;li&gt;
                Support &lt;code&gt;&lt;span class=&quot;special&quot;&gt;\&lt;/span&gt;&lt;span class=&quot;keyword&quot;&gt;throw&lt;/span&gt;&lt;/code&gt;.
              &lt;/li&gt;
              &lt;li&gt;
                Support global variables and enums.
              &lt;/li&gt;
              &lt;li&gt;
                Better support for documentation written in function and method bodies.
              &lt;/li&gt;
              &lt;li&gt;
                Workaround a problem with doxygen 1.5.8's xml output (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2937&quot;&gt;#2937&lt;/a&gt;).
              &lt;/li&gt;
            &lt;/ul&gt;
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/tools/quickbook/index.html&quot;&gt;Quickbook&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Return an error code and error count if there are any errors (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1399&quot;&gt;#1399&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Support both windows and cygwin paths at the compile line when compiled
            with cygwin.
          &lt;/li&gt;
          &lt;li&gt;
            Fix some issues with C++ and Python code:
            &lt;ul&gt;
              &lt;li&gt;
                Fail gracefully for a mismatched &lt;code&gt;&lt;span class=&quot;char&quot;&gt;''&lt;/span&gt;&lt;/code&gt;.
              &lt;/li&gt;
              &lt;li&gt;
                Warn if any unexpected character are encountered and write them out
                properly (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1170&quot;&gt;#1170&lt;/a&gt;).
              &lt;/li&gt;
              &lt;li&gt;
                Fix a bug for hex encoded characters in strings (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2860&quot;&gt;#2860&lt;/a&gt;).
              &lt;/li&gt;
            &lt;/ul&gt;
          &lt;/li&gt;
          &lt;li&gt;
            Improved testing, including tests for expected failures.
          &lt;/li&gt;
          &lt;li&gt;
            Generate valid document info for document types other than &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;library&lt;/span&gt;&lt;/code&gt; (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2711&quot;&gt;#2711&lt;/a&gt;):
            &lt;ul&gt;
              &lt;li&gt;
                Remove library specific attributes.
              &lt;/li&gt;
              &lt;li&gt;
                Put title before info block.
              &lt;/li&gt;
            &lt;/ul&gt;
          &lt;/li&gt;
          &lt;li&gt;
            Fix a bug when calling templates.
          &lt;/li&gt;
          &lt;li&gt;
            Less warnings when built using gcc.
          &lt;/li&gt;
          &lt;li&gt;
            Small documentation improvements (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1213&quot;&gt;#1213&lt;/a&gt;,
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2701&quot;&gt;#2701&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Fix a bug with xinclude pages when outdir is the current directory (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2921&quot;&gt;#2921&lt;/a&gt;).
          &lt;/li&gt;

            Updated documentation to show rvalue-references functions instead of
            emulation functions.
          &lt;/li&gt;
          &lt;li&gt;
            More non-copyable classes are now movable.
          &lt;/li&gt;
          &lt;li&gt;
            Move-constructor and assignments now leave moved object in default-constructed
            state instead of just swapping contents.

          &lt;li&gt;
            New treap-based containers: treap, treap_set, treap_multiset.
          &lt;/li&gt;
          &lt;li&gt;
            Corrected compilation bug for Windows-based 64 bit compilers.

          &lt;/li&gt;
          &lt;li&gt;
            Fixed code so that it compiles in GCC's -pedantic mode (bug report &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1451&quot;&gt;#1451&lt;/a&gt;).

          &lt;/li&gt;
          &lt;li&gt;

          &lt;/li&gt;
          &lt;li&gt;

            macros.
          &lt;/li&gt;
          &lt;li&gt;
            Add &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_PROTO_REPEAT&lt;/span&gt;&lt;/code&gt;
            and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_PROTO_LOCAL_ITERATE&lt;/span&gt;&lt;/code&gt;
            macros to help with repetitive code generation
          &lt;/li&gt;
          &lt;li&gt;
            Support for nullary expressions with tag types other than &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;proto&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;tag&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;terminal&lt;/span&gt;&lt;/code&gt;
          &lt;/li&gt;
          &lt;li&gt;
            Allow 0- and 1-argument variants of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;proto&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;or_&lt;/span&gt;&lt;/code&gt;

            &lt;em&gt;Breaking change&lt;/em&gt;: empty expressions,
            and empty alternatives are now allowed when using the Perl regular expression
            syntax. This change has been added for Perl compatibility, when the new
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;syntax_option_type&lt;/span&gt;&lt;/code&gt; &lt;em&gt;no_empty_expressions&lt;/em&gt;
            is set then the old behaviour is preserved and empty expressions are
            prohibited. This is issue &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/1081&quot;&gt;#1081&lt;/a&gt;.
          &lt;/li&gt;
          &lt;li&gt;
            Added support for Perl style ${n} expressions in format strings (issue
            &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2556&quot;&gt;#2556&lt;/a&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Added support for accessing the location of sub-expressions within the
            regular expression string (issue &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2269&quot;&gt;#2269&lt;/a&gt;).
          &lt;/li&gt;

            Fixed compiler compatibility issues &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/2244&quot;&gt;#2244&lt;/a&gt;,

        &lt;ul&gt;
          &lt;li&gt;
            No longer catches unhandled exceptions in threads as this debuggers couldn't
            identify the cause of unhandled exceptions in threads. An unhandled exception
            will still cause the application to terminate.

        &lt;ul&gt;
          &lt;li&gt;
            Added support for the TR1 math functions and the unordered containers.

        &lt;ul&gt;
          &lt;li&gt;
            Added support for Codegear intrinsics.
          &lt;/li&gt;
          &lt;li&gt;
            Minor tweaks to warning suppression and alignment_of code.

          &lt;/li&gt;
          &lt;li&gt;
            Use a larger prime number list for selecting the number of buckets.
          &lt;/li&gt;
          &lt;li&gt;
            Use &lt;a href=&quot;/libs/type_traits/doc/html/boost_typetraits/category/alignment.html&quot;&gt;aligned
            storage&lt;/a&gt; to store the types.
          &lt;/li&gt;
          &lt;li&gt;
            Add support for C++0x initializer lists where they're available.
          &lt;/li&gt;

        Experimental support for building Boost with &lt;a href=&quot;http://www.cmake.org/&quot;&gt;CMake&lt;/a&gt;
        has been introduced in this version. For more details see the &lt;a href=&quot;https://svn.boost.org/trac/boost/wiki/CMake&quot;&gt;wiki&lt;/a&gt;,
        Discussion is taking place on the &lt;a href=&quot;http://lists.boost.org/mailman/listinfo.cgi/boost-cmake&quot;&gt;Boost-cmake
        mailing list&lt;/a&gt;.
      &lt;/li&gt;
      &lt;li&gt;
        Fixed subversion properties for several files. Most notably, unix shell scripts
        should always have unix line endings, even in the windows packages.
      &lt;/li&gt;
    &lt;/ul&gt;
  &lt;/div&gt;

        &lt;ul&gt;
          &lt;li&gt;
            Expression template library and compiler construction toolkit for domain-specific
            embedded languages, from Eric Niebler.
          &lt;/li&gt;
        &lt;/ul&gt;

    &lt;ul&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/asio/index.html&quot;&gt;Asio&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Enhanced CompletionCondition concept with the signature &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;size_t&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;CompletionCondition&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;error_code&lt;/span&gt;
            &lt;span class=&quot;identifier&quot;&gt;ec&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;,&lt;/span&gt;
            &lt;span class=&quot;identifier&quot;&gt;size_t&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;total&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)&lt;/span&gt;&lt;/code&gt;, where the return value indicates the
            maximum number of bytes to be transferred on the next read or write operation.
            (The old CompletionCondition signature is still supported for backwards
            compatibility).
          &lt;/li&gt;
          &lt;li&gt;
            New windows::overlapped_ptr class to allow arbitrary overlapped I/O functions
            (such as TransmitFile) to be used with Asio.
          &lt;/li&gt;
          &lt;li&gt;
            On recent versions of Linux, an eventfd descriptor is now used (rather
            than a pipe) to interrupt a blocked select/epoll reactor.
          &lt;/li&gt;
          &lt;li&gt;
            Added const overloads of lowest_layer().
          &lt;/li&gt;
          &lt;li&gt;
            Synchronous read, write, accept and connect operations are now thread
            safe (meaning that it is now permitted to perform concurrent synchronous
            operations on an individual socket, if supported by the OS).
          &lt;/li&gt;
          &lt;li&gt;
            Reactor-based io_service implementations now use lazy initialisation
            to reduce the memory usage of an io_service object used only as a message
            queue.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/circular_buffer/index.html&quot;&gt;Circular Buffer&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Added new methods &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;is_linearized&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;rotate&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;const_iterator&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)&lt;/span&gt;&lt;/code&gt;.
          &lt;/li&gt;
          &lt;li&gt;
            Minor bug fixes and documentation updates.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/dynamic_bitset/&quot;&gt;Dynamic Bitset&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Constructor &amp;quot;do the right thing&amp;quot; dispatch, a la standard sequence
            containers (follows the proposed resolution of &lt;a href=&quot;http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-defects.html#438&quot;&gt;library
            issue 438&lt;/a&gt;, currently in the &lt;tt&gt;C++0x&lt;/tt&gt; working
            paper).
          &lt;/li&gt;
          &lt;li&gt;
            Improvements to documentation, code examples and implementation.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/exception/index.html&quot;&gt;Exception&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Support for non-RTTI builds.
          &lt;/li&gt;
          &lt;li&gt;
            Optimizations.
          &lt;/li&gt;
          &lt;li&gt;
            A new macro &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_THROW_EXCEPTION&lt;/span&gt;&lt;/code&gt;
            which can be used instead of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;throw_exception&lt;/span&gt;&lt;/code&gt;
            when throwing, to automatically record information about the location
            of the throw in the exception object.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/functional/hash/index.html&quot;&gt;Hash&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Minor bug fix (&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/2264&quot;&gt;ticket
            2264&lt;/a&gt;).
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/interprocess/index.html&quot;&gt;Interprocess&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Added placement insertion (&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;emplace&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;emplace_back&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;...) methods to containers.
          &lt;/li&gt;
          &lt;li&gt;
            Containers can be used now in recursive types.
          &lt;/li&gt;
          &lt;li&gt;
            Minor bug fixes.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/intrusive/index.html&quot;&gt;Intrusive&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Intrusive now takes advantage of compilers with variadic templates.
          &lt;/li&gt;
          &lt;li&gt;
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;clone_from&lt;/span&gt;&lt;/code&gt; functions
            now copy predicates and hash functions of associative containers.
          &lt;/li&gt;
          &lt;li&gt;
            Added incremental hashing to unordered containers via &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;incremental&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt; option.
          &lt;/li&gt;
          &lt;li&gt;
            Minor bug fixes.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/math/doc/sf_and_dist/html/index.html&quot;&gt;Math.Special
        Functions&lt;/a&gt;:&lt;/span&gt;
   Improved accuracy and testing of the inverse hypergeometric
        functions.
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/type_traits/index.html&quot;&gt;Type Traits&lt;/a&gt;:&lt;/span&gt;
   Added
        better support for the Codegear compiler.
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/unordered/index.html&quot;&gt;Unordered&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Rename overload of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;emplace&lt;/span&gt;&lt;/code&gt;
            with hint, to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;emplace_hint&lt;/span&gt;&lt;/code&gt;
            as specified in &lt;a href=&quot;http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2008/n2691.pdf&quot;&gt;n2691&lt;/a&gt;.
          &lt;/li&gt;
          &lt;li&gt;
            Provide forwarding headers at &lt;code&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;unordered&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;unordered_map_fwd&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;
            and &lt;code&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;unordered&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;unordered_set_fwd&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;hpp&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;.
          &lt;/li&gt;
          &lt;li&gt;
            Move all of the implementation inside the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;unordered&lt;/span&gt;&lt;/code&gt;
            directory.
          &lt;/li&gt;

    &lt;ul&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/accumulators/index.html&quot;&gt;Accumulators&lt;/a&gt;:&lt;/span&gt; Framework
        for incremental calculation, and collection of statistical accumulators,
        from Eric Niebler.
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/exception/doc/boost-exception.html&quot;&gt;Exception&lt;/a&gt;:&lt;/span&gt; 
  A
        library for transporting of arbitrary data in exception objects, and transporting
        of exceptions between threads, from Emil Dotchevski.
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/units/index.html&quot;&gt;Units&lt;/a&gt;:&lt;/span&gt;
  Zero-overhead dimensional
        analysis and unit/quantity manipulation and conversion, from Matthias Schabel
        and Steven Watanabe
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/unordered/index.html&quot;&gt;Unordered&lt;/a&gt;:&lt;/span&gt; 
  Unordered

    &lt;ul&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/asio/index.html&quot;&gt;Asio&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Added support for serial ports.
          &lt;/li&gt;
          &lt;li&gt;
            Added support for UNIX domain sockets.
          &lt;/li&gt;
          &lt;li&gt;
            Added support for raw sockets and ICMP.
          &lt;/li&gt;
          &lt;li&gt;
            Added wrappers for POSIX stream-oriented file descriptors (excluding
            regular files).
          &lt;/li&gt;
          &lt;li&gt;
            Added wrappers for Windows stream-oriented &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;HANDLE&lt;/span&gt;&lt;/code&gt;s
            such as named pipes (requires &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;HANDLE&lt;/span&gt;&lt;/code&gt;s
            that work with I/O completion ports).
          &lt;/li&gt;
          &lt;li&gt;
            Added wrappers for Windows random-access &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;HANDLE&lt;/span&gt;&lt;/code&gt;s
            such as files (requires &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;HANDLE&lt;/span&gt;&lt;/code&gt;s
            that work with I/O completion ports).
          &lt;/li&gt;
          &lt;li&gt;
            Added support for reactor-style operations (i.e. they report readiness
            but perform no I/O) using a new &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;null_buffers&lt;/span&gt;&lt;/code&gt;
            type.
          &lt;/li&gt;
          &lt;li&gt;
            Added an iterator type for bytewise traversal of buffer sequences.
          &lt;/li&gt;
          &lt;li&gt;
            Added new &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;read_until&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;async_read_until&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; overloads that take a user-defined
            function object for locating message boundaries.
          &lt;/li&gt;
          &lt;li&gt;
            Added an experimental two-lock queue (enabled by defining &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_ASIO_ENABLE_TWO_LOCK_QUEUE&lt;/span&gt;&lt;/code&gt;) that
            may provide better &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;io_service&lt;/span&gt;&lt;/code&gt;
            scalability across many processors.
          &lt;/li&gt;
          &lt;li&gt;
            Various fixes, performance improvements, and more complete coverage of
            the custom memory allocation support.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/assign/index.html&quot;&gt;Assign&lt;/a&gt;:&lt;/span&gt;
  &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;list_of&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
        (and its variants) now has overloaded comparison operators. This allows you
        to write test code such as &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_CHECK_EQUAL&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;my_container&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;,&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;list_of&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;number&quot;&gt;2&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)(&lt;/span&gt;&lt;span class=&quot;number&quot;&gt;3&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)(&lt;/span&gt;&lt;span class=&quot;number&quot;&gt;4&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)(&lt;/span&gt;&lt;span class=&quot;number&quot;&gt;5&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)&lt;/span&gt;
        &lt;span class=&quot;special&quot;&gt;);&lt;/span&gt;&lt;/code&gt;.
      &lt;/li&gt;
      &lt;li&gt;

            option is used in the hook.
          &lt;/li&gt;
          &lt;li&gt;
            Implementation changed to avoid explicit use of &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;try&lt;/span&gt;&lt;/code&gt;-&lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;catch&lt;/span&gt;&lt;/code&gt; blocks and be compilable with exceptions

  Integrated the
        &amp;quot;Classic&amp;quot; Spirit V1.8.x code base with Spirit V2, &amp;quot;The New
        Generation&amp;quot;. See &lt;a href=&quot;/libs/spirit/classic/change_log.html&quot;&gt;Change

          &lt;li&gt;
            New generic &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;lock&lt;/span&gt;&lt;/code&gt; and
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;try_lock&lt;/span&gt;&lt;/code&gt; functions for
            locking multiple mutexes at once.
          &lt;/li&gt;
          &lt;li&gt;
            Rvalue reference support for move semantics where the compilers supports
            it.
          &lt;/li&gt;
          &lt;li&gt;
            A few bugs fixed and missing functions added (including the serious win32
            condition variable bug).
          &lt;/li&gt;
          &lt;li&gt;
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;scoped_try_lock&lt;/span&gt;&lt;/code&gt; types
            are now backwards-compatible with Boost 1.34.0 and previous releases.
          &lt;/li&gt;
          &lt;li&gt;
            Support for passing function arguments to the thread function by supplying
            additional arguments to the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;thread&lt;/span&gt;&lt;/code&gt;
            constructor.
          &lt;/li&gt;
          &lt;li&gt;
            Backwards-compatibility overloads added for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;timed_lock&lt;/span&gt;&lt;/code&gt;
            and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;timed_wait&lt;/span&gt;&lt;/code&gt; functions
            to allow use of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;xtime&lt;/span&gt;&lt;/code&gt;
            for timeouts.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/wave/index.html&quot;&gt;Wave&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Wave V2.0 is a new major release introducing some breaking API changes,
            preventing it to be used with Boost versions earlier than V1.36.0. Mainly,
            the API and hook interface have been streamlined for more consistency.
          &lt;/li&gt;
          &lt;li&gt;
            Fixed a couple of bugs, improved regression test system to include testing
            of the preporcessing hooks interface (for details see: &lt;a href=&quot;/libs/wave/ChangeLog&quot;&gt;Changelog&lt;/a&gt;).
          &lt;/li&gt;

        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/xpressive/index.html&quot;&gt;Xpressive&lt;/a&gt;:&lt;/span&gt; 
  Regular
        expressions that can be written as strings or as expression templates, and
        that can refer to each other and themselves recursively with the power of
        context-free grammars, from Eric Niebler.
        &lt;ul&gt;
          &lt;li&gt;
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;skip&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
            for specifying which parts of the input sequence to ignore when matching
            it against a regex.
          &lt;/li&gt;
          &lt;li&gt;
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;regex_replace&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
            accepts formatter objects and formatter expressions in addition to format
            strings.
          &lt;/li&gt;
          &lt;li&gt;
            Range-based &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;regex_replace&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; algorithm.
          &lt;/li&gt;
          &lt;li&gt;
            Fix crash when semantic actions are placed in look-aheads, look-behinds
            or independent sub-expressions.
          &lt;/li&gt;
        &lt;/ul&gt;

        &lt;ul&gt;

          &lt;/li&gt;
          &lt;li&gt;
            Improved the algorithm for hashing floating point numbers.
          &lt;/li&gt;
          &lt;li&gt;
            A few bug and warning fixes.

        for defining streams, stream buffers and i/o filters, from Jonathan Turkanis.
        Highlights:
        &lt;ul&gt;
          &lt;li&gt;
            Clarified the semantics of close(). This fixes several bugs but will
            break some existing code. See &lt;a href=&quot;/libs/iostreams/doc/index.html?path=12&quot;&gt;Release
            Notes&lt;/a&gt; for details.
          &lt;/li&gt;
          &lt;li&gt;
            Numerous other bug fixes and optimizations.

        &lt;ul&gt;
          &lt;li&gt;
            Added &amp;quot;dimensionality&amp;quot; compile-time constante to the MultiArray
            concept.
          &lt;/li&gt;
          &lt;li&gt;
            For greater control over error situations, uses of C++ assert have been
            replaced with BOOST_ASSERT.
          &lt;/li&gt;
          &lt;li&gt;
            Fixed a bug with simultaneous resizing and reindexing.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/multi_index/doc/index.html&quot;&gt;Multi-index Containers&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            New &lt;a href=&quot;/libs/multi_index/doc/tutorial/key_extraction.html#global_fun&quot;&gt;&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;global_fun&lt;/span&gt;&lt;/code&gt;&lt;/a&gt; predefined key extractor.
          &lt;/li&gt;
          &lt;li&gt;
            Added &lt;a href=&quot;/libs/multi_index/doc/tutorial/indices.html#iterator_to&quot;&gt;&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;iterator_to&lt;/span&gt;&lt;/code&gt;&lt;/a&gt; facility.
          &lt;/li&gt;
          &lt;li&gt;
            Included &lt;a href=&quot;/libs/multi_index/doc/tutorial/creation.html#special_allocator&quot;&gt;support
            for non-standard allocators&lt;/a&gt; such as those of &lt;a href=&quot;/libs/interprocess/index.html&quot;&gt;Boost.Interprocess&lt;/a&gt;,
            which makes &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;multi_index_container&lt;/span&gt;&lt;/code&gt;s
            placeable in shared memory.
          &lt;/li&gt;
          &lt;li&gt;
            New versions of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;modify&lt;/span&gt;&lt;/code&gt;
            and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;modify_key&lt;/span&gt;&lt;/code&gt; with rollback,
            as described in the &lt;a href=&quot;/libs/multi_index/doc/tutorial/basics.html#ord_updating&quot;&gt;tutorial&lt;/a&gt;.
          &lt;/li&gt;
          &lt;li&gt;
            A number of optimizations and minor improvements have also been included.
            For a complete list of changes, see the library &lt;a href=&quot;/libs/multi_index/doc/release_notes.html#boost_1_35&quot;&gt;release
            notes&lt;/a&gt;.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/serialization/index.html&quot;&gt;Serialization&lt;/a&gt;:&lt;/span&gt; 
   Boost.Serialization
        has been updated with optimizations for dense arrays.
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/thread/index.html&quot;&gt;Thread&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            The Thread library has been updated to be more in line with the C++0x
            working draft.
          &lt;/li&gt;
          &lt;li&gt;
            Instances of boost::thread and of the various lock types are now movable.
          &lt;/li&gt;
          &lt;li&gt;
            Threads can be interrupted at interruption points.
          &lt;/li&gt;
          &lt;li&gt;
            Condition variables can now be used with any type that implements the
            Lockable concept, through the use of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;condition_variable_any&lt;/span&gt;&lt;/code&gt;
            (&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;condition&lt;/span&gt;&lt;/code&gt; is a typedef to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;condition_variable_any&lt;/span&gt;&lt;/code&gt;, provided for
            backwards compatibility). &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;condition_variable&lt;/span&gt;&lt;/code&gt;
            is provided as an optimization, and will only work with &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;unique_lock&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;mutex&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;
            (&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;mutex&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;scoped_lock&lt;/span&gt;&lt;/code&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Thread IDs are separated from boost::thread, so a thread can obtain it's
            own ID (using &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;this_thread&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;get_id&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;),
            and IDs can be used as keys in associative containers, as they have the
            full set of comparison operators.
          &lt;/li&gt;
          &lt;li&gt;
            Timeouts are now implemented using the Boost DateTime library, through
            a typedef &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;system_time&lt;/span&gt;&lt;/code&gt; for absolute timeouts,
            and with support for relative timeouts in many cases. &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;xtime&lt;/span&gt;&lt;/code&gt;
            is supported for backwards compatibility only.
          &lt;/li&gt;
          &lt;li&gt;
            Locks are implemented as publicly accessible templates &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;lock_guard&lt;/span&gt;&lt;/code&gt;, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;unique_lock&lt;/span&gt;&lt;/code&gt;,
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;shared_lock&lt;/span&gt;&lt;/code&gt;, and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;upgrade_lock&lt;/span&gt;&lt;/code&gt;,
            which are templated on the type of the mutex. The Lockable concept has
            been extended to include publicly available &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;lock&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;unlock&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; member functions, which are used by
            the lock types.
          &lt;/li&gt;
          &lt;li&gt;
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;try_mutex&lt;/span&gt;&lt;/code&gt; has been removed, and the
            functionality subsumed into &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;mutex&lt;/span&gt;&lt;/code&gt;.
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;try_mutex&lt;/span&gt;&lt;/code&gt; is left as a typedef, but
            is no longer a separate class.
          &lt;/li&gt;
          &lt;li&gt;
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;recursive_try_mutex&lt;/span&gt;&lt;/code&gt; has been removed,
            and the functionality subsumed into &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;recursive_mutex&lt;/span&gt;&lt;/code&gt;.
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;recursive_try_mutex&lt;/span&gt;&lt;/code&gt; is left as a typedef,
            but is no longer a separate class.
          &lt;/li&gt;
          &lt;li&gt;
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;detail&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;thread&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;lock_ops&lt;/span&gt;&lt;/code&gt; has been removed. Code that
            relies on the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;lock_ops&lt;/span&gt;&lt;/code&gt;
            implementation detail will no longer work, as this has been removed,
            as it is no longer necessary now that mutex types now have public &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;lock&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
            and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;unlock&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
            member functions.
          &lt;/li&gt;
          &lt;li&gt;
            &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;scoped_lock&lt;/span&gt;&lt;/code&gt; constructors
            with a second parameter of type bool are no longer provided. With previous
            boost releases, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;mutex&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;scoped_lock&lt;/span&gt;
            &lt;span class=&quot;identifier&quot;&gt;some_lock&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;some_mutex&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;,&lt;/span&gt;&lt;span class=&quot;keyword&quot;&gt;false&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;);&lt;/span&gt;&lt;/code&gt;
            could be used to create a lock object that was associated with a mutex,
            but did not lock it on construction. This facility has now been replaced
            with the constructor that takes a &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;defer_lock_type&lt;/span&gt;&lt;/code&gt;
            as the second parameter: &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;mutex&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;scoped_lock&lt;/span&gt;
            &lt;span class=&quot;identifier&quot;&gt;some_lock&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;some_mutex&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;,&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;defer_lock&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;);&lt;/span&gt;&lt;/code&gt;
          &lt;/li&gt;
          &lt;li&gt;
            The broken &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;read_write_mutex&lt;/span&gt;&lt;/code&gt; has been replaced
            with &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;shared_mutex&lt;/span&gt;&lt;/code&gt;.

        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/wave/index.html&quot;&gt;Wave&lt;/a&gt;:&lt;/span&gt; Standards conformant
        implementation of the mandated C99/C++ preprocessor functionality packed
        behind an easy to use iterator interface, from Hartmut Kaiser. Highlights:
        &lt;ul&gt;
          &lt;li&gt;
            Added the possibility to continue the preprocessing after an error occured.
          &lt;/li&gt;
          &lt;li&gt;
            Added the macro introspection API to the wave::context object.
          &lt;/li&gt;
          &lt;li&gt;
            Added threading support to the library.
          &lt;/li&gt;
          &lt;li&gt;
            Improved the overall performance by upto 30%.
          &lt;/li&gt;
          &lt;li&gt;
            Changed and unified preprocessor hook interface (this is an interface
            breaking change!), added several new preprocessor hook functions.
          &lt;/li&gt;
          &lt;li&gt;
            Added serialization support.
          &lt;/li&gt;
          &lt;li&gt;
            Added new examples (for instance: Hannibal - a partial C++ parser, by
            Danny Havenith).
          &lt;/li&gt;
          &lt;li&gt;
            Added a new lexical analyzer based on Ben Hansons Lexertl library.
          &lt;/li&gt;
          &lt;li&gt;
            Fixed a large number of other bugs and problems.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;

        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/xpressive/index.html&quot;&gt;Xpressive&lt;/a&gt;:&lt;/span&gt; Regular
        expressions that can be written as strings or as expression templates, and
        that can refer to each other and themselves recursively with the power of
        context-free grammars, from Eric Niebler. Highlights:
        &lt;ul&gt;
          &lt;li&gt;
            Added &lt;em&gt;semantic actions&lt;/em&gt; to static regexes. A semantic
            action is code that executes when part of a regular expression matches.
          &lt;/li&gt;
          &lt;li&gt;
            Added &lt;em&gt;custom assertions&lt;/em&gt; to static regexes. A custom
            assertion is a Boolean predicate that can participate in the regex match.
          &lt;/li&gt;
          &lt;li&gt;
            Added &lt;em&gt;named regexes&lt;/em&gt; for embedding a static or dynamic
            regex into a dynamic regex. This can be used to create dynamic regex
            grammars.
          &lt;/li&gt;
          &lt;li&gt;
            Added &lt;em&gt;named captures&lt;/em&gt; to dynamic regexes, like Perl.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;

  &lt;p&gt;
    This is a bug fix release addressing many problems with the 1.34.0 release. It
    is a recommended upgrade for all users of Boost 1.34.0. For a complete list of
    fixes see &lt;a href=&quot;http://svn.boost.org/trac/boost/query?status=closed&amp;amp;milestone=Boost+1.34.1&quot;&gt;Boost

    &lt;p&gt;
      New in this release is improved support for the IBM XL C/C++ compiler.
    &lt;/p&gt;
    &lt;p&gt;
      Boost is tested on a wide range of compilers and platforms. Since Boost libraries
      rely on modern C++ features not available in all compilers, not all Boost libraries
      will work with every compiler. New in this release The following compilers
      and platforms have been extensively tested with Boost, although many other
      compilers and platforms will work as well. For more information, see the &lt;a href=&quot;http://www.boost.org/regression/release/user/&quot;&gt;regression test results&lt;/a&gt;.

        implementation of the C++ Technical Report on Standard Library Extensions,
        from John Maddock. This library does not itself implement the TR1 components,
        rather it's a thin wrapper that will include your standard library's TR1
        implementation (if it has one), otherwise it will include the Boost Library
        equivalents, and import them into namespace &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;std&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;tr1&lt;/span&gt;&lt;/code&gt;.

  Boost.Function
        now implements a small buffer optimization, which can drastically improve
        the performance when copying or constructing Boost.Function objects storing
        small function objects. For instance, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;bind&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&amp;amp;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;X&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;:&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;foo&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;,&lt;/span&gt;
        &lt;span class=&quot;special&quot;&gt;&amp;amp;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;x&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;,&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;_1&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;,&lt;/span&gt;
        &lt;span class=&quot;identifier&quot;&gt;_2&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)&lt;/span&gt;&lt;/code&gt;
        requires no heap allocation when placed into a Boost.Function object.

          &lt;li&gt;
            Integrated support for wrapping C++ functions built with the parameter

          &lt;li&gt;
            Negative indexes support (like Perl) in various algorihtms (&lt;code&gt;&lt;span class=&quot;special&quot;&gt;*&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;_head&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;tail&lt;/span&gt;&lt;/code&gt;,

        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/doc/libs/1_34_0/libs/wave/index.html&quot;&gt;Wave Library&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Wave now correctly recognizes pp-number tokens as mandated by the C++
            Standard, which are converted to C++ tokens right before they are returned
            from the library.
          &lt;/li&gt;
          &lt;li&gt;
            Several new preprocessing hooks have been added. For a complete description
            please refer to the related documentation page: &lt;a href=&quot;/doc/libs/1_34_0/libs/wave/doc/class_reference_ctxpolicy.html&quot;&gt;The
            Context Policy&lt;/a&gt;.
          &lt;/li&gt;
          &lt;li&gt;
            Shared library (dll) support has been added for the generated Wave libraries.
          &lt;/li&gt;
          &lt;li&gt;
            The overall error handling has been improved. It is now possible to recover
            and continue after an error or a warning was issued.
          &lt;/li&gt;
          &lt;li&gt;
            Support for optional comment and/or full whitespace preservation in the
            generated output stream has been added.
          &lt;/li&gt;
          &lt;li&gt;
            The Wave library now performs automatic include guard detection to avoid
            accessing header files more than once, if appropriate.
          &lt;/li&gt;
          &lt;li&gt;
            Full interactive mode has been added to the Wave tool. Now the Wave tool
            can be used just like Python or Perl for instance to interactively try
            out your BOOST_PP macros. Additionally it is now possible to load and
            save the current state of an interactive session (macro tables et.al.).
          &lt;/li&gt;
          &lt;li&gt;
            The overall performance has been improved by upto 40-60%, depending on
            the concrete files to process.
          &lt;/li&gt;
          &lt;li&gt;
            Support for new pragmas has been added allowing to control certain library
            features from inside the preprocessed sources (partial output redirection,
            control of generated whitespace and #line directives).
          &lt;/li&gt;
          &lt;li&gt;
            Optional support for #pragma message &amp;quot;...&amp;quot; has been added.
          &lt;/li&gt;
          &lt;li&gt;
            This version also includes a number of bug fixes and usage improvements.

      Boost is tested on a wide range of compilers and platforms. Since Boost libraries
      rely on modern C++ features not available in all compilers, not all Boost libraries
      will work with every compiler. The following compilers and platforms have been
      extensively tested with Boost, although many other compilers and platforms
      will work as well. For more information, see the &lt;a href=&quot;http://www.boost.org/regression/release/user/&quot;&gt;regression
      test results&lt;/a&gt;.

        &lt;ul&gt;
          &lt;li&gt;
            The build now assumes Python 2.4 by default, rather than 2.2
          &lt;/li&gt;
          &lt;li&gt;
            Support Python that's built without Unicode support
          &lt;/li&gt;
          &lt;li&gt;
            Support for wrapping classes with overloaded address-of (&lt;code&gt;&lt;span class=&quot;special&quot;&gt;&amp;amp;&lt;/span&gt;&lt;/code&gt;) operators
          &lt;/li&gt;
        &lt;/ul&gt;

        Library&lt;/a&gt;:&lt;/span&gt; Fixed problems under Metrowerks CodeWarrior on PowerPC (Mac
        OS X) with inlining on, GNU GCC on PowerPC 64.
      &lt;/li&gt;
      &lt;li&gt;

        Library&lt;/a&gt;:&lt;/span&gt;
  Improved the interface for accessing a chain's components,
        added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;is_open&lt;/span&gt;&lt;/code&gt; members to
        the file and file descriptor devices, fixed memory-mapped files on Windows,
        and made minor changes to the documentation.
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/doc/libs/1_33_1/libs/python/doc/index.html&quot;&gt;Boost.Python&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Added support for docstrings on nonstatic properties.
          &lt;/li&gt;
          &lt;li&gt;
            We now export the client-provided docstrings for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;init&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;optional&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt; &lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;
            and &lt;em&gt;XXX&lt;/em&gt;&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;_FUNCTION_OVERLOADS&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; for only the last overload.
          &lt;/li&gt;
          &lt;li&gt;
            Support for Embedded VC++ 4 and GCC-3.3 on MacOS added
          &lt;/li&gt;
          &lt;li&gt;
            Introduced better support for rvalue from-python conversions of shared_ptr.
          &lt;/li&gt;
          &lt;li&gt;
            Support for exposing &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;vector&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;T&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;*&amp;gt;&lt;/span&gt;&lt;/code&gt; with the indexing suite.
          &lt;/li&gt;
          &lt;li&gt;
            updated visual studio project build file.
          &lt;/li&gt;
          &lt;li&gt;
            Added search feature to the index page.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;

        Library&lt;/a&gt;:&lt;/span&gt;
  Fixed the points example.
      &lt;/li&gt;

        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/doc/libs/1_33_1/libs/multi_index/doc/index.html&quot;&gt;Multi-index
        Containers Library&lt;/a&gt;:&lt;/span&gt;
  Fixed a problem with multithreaded code, and other
        minor changes. Refer to the library &lt;a href=&quot;/doc/libs/1_33_1/libs/multi_index/doc/release_notes.html#boost_1_33_1&quot;&gt;release
        notes&lt;/a&gt; for further details.
      &lt;/li&gt;

        Library&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Fixed a problem with the relaxed heap on x86 Linux (fixes bug in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;dijkstra_shortest_paths&lt;/span&gt;&lt;/code&gt;).
          &lt;/li&gt;
          &lt;li&gt;
            Fixed problems with &lt;a href=&quot;/doc/libs/1_33_1/libs/graph/doc/cuthill_mckee_ordering.html&quot;&gt;&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;cuthill_mckee_ordering&lt;/span&gt;&lt;/code&gt;&lt;/a&gt; and

            results.
          &lt;/li&gt;
          &lt;li&gt;
            Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;color_map&lt;/span&gt;&lt;/code&gt; parameter
            to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;dijkstra_shortest_paths&lt;/span&gt;&lt;/code&gt;.
          &lt;/li&gt;

    &lt;p&gt;
      Boost is tested on a wide range of compilers and platforms. Since Boost libraries
      rely on modern C++ features not available in all compilers, not all Boost libraries
      will work with every compiler. The following compilers and platforms have been
      extensively tested with Boost, although many other compilers and platforms
      will work as well. For more information, see the &lt;a href=&quot;http://www.boost.org/regression/release/user/&quot;&gt;regression
      test results&lt;/a&gt;.
    &lt;/p&gt;
    &lt;p&gt;
      &lt;em&gt;New for this release&lt;/em&gt;: Support for building
      with the newest STLport-5.0 was added. The support includes building with MinGW
      Runtime 3.8 plus STLport-5.0 improved to support wide character operations.
      Apple GCC 4.0, HP Tru64 C++, and Microsoft Visual C++ 8.0 are supported platforms.
      We have added an experimental autoconf-like &lt;tt&gt;configure&lt;/tt&gt; script
      for Unix-like systems: run &lt;tt&gt;configure --help&lt;/tt&gt; for more information.
    &lt;/p&gt;

        support the non-standard &amp;quot;Safe&amp;quot; C++ Library shipping with Visual
        C++ 8.0, which may result in many spurious warnings from Boost headers and
        other standards-conforming C++ code. To suppress these warnings, define the
        macro &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;_SCL_SECURE_NO_DEPRECATE&lt;/span&gt;&lt;/code&gt;.

            from Jeremy Siek, Janusz Piwowarski, and Doug Gregor.
          &lt;/li&gt;
          &lt;li&gt;

          &lt;li&gt;
            &lt;a href=&quot;/doc/libs/1_33_1/libs/graph/doc/cuthill_mckee_ordering.html&quot;&gt;&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;cuthill&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;mckee&lt;/span&gt;
            &lt;span class=&quot;identifier&quot;&gt;ordering&lt;/span&gt;&lt;/code&gt;&lt;/a&gt; has been recast

            &lt;span class=&quot;identifier&quot;&gt;paths&lt;/span&gt;&lt;/code&gt;&lt;/a&gt; now uses a relaxed
            heap [&lt;a href=&quot;/doc/libs/1_33_1/libs/graph/doc/bibliography.html#driscoll88&quot;&gt;61&lt;/a&gt;]
            as its priority queue, improving its complexity to O(V log V) and improving
            real-world performance for larger graphs.
          &lt;/li&gt;
          &lt;li&gt;
            &lt;a href=&quot;/doc/libs/1_33_1/libs/graph/doc/read_graphviz.html&quot;&gt;&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;read&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;graphviz&lt;/span&gt;&lt;/code&gt;&lt;/a&gt;
            now has a new, Spirit-based parser that works for all graph types and
            supports arbitrary properties on the graph, from Ron Garcia. The old,
            Bison-based GraphViz reader has been deprecated and will be removed in
            a future Boost release. &lt;a href=&quot;/doc/libs/1_33_1/libs/graph/doc/write-graphviz.html&quot;&gt;&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;write&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;graphviz&lt;/span&gt;&lt;/code&gt;&lt;/a&gt;
            also supports dynamic properties.
          &lt;/li&gt;
          &lt;li&gt;
            &lt;a href=&quot;/doc/libs/1_33_1/libs/graph/doc/subgraph.html&quot;&gt;&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;subgraph&lt;/span&gt;&lt;/code&gt;&lt;/a&gt;: &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;get_property&lt;/span&gt;&lt;/code&gt;
            now refers to the subgraph property, not the root graph's property.
          &lt;/li&gt;

            See the &lt;a href=&quot;/doc/libs/1_33_1/libs/graph/doc/history.html#by-version&quot;&gt;history&lt;/a&gt;

            indices&lt;/a&gt;.
          &lt;/li&gt;
          &lt;li&gt;
            Added &lt;a href=&quot;/doc/libs/1_33_1/libs/multi_index/doc/tutorial/creation.html#serialization&quot;&gt;serialization
            support&lt;/a&gt;.
          &lt;/li&gt;

        Options Library&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Option descriptions are now printed with word wrapping.
          &lt;/li&gt;
          &lt;li&gt;
            Command line parser can bypass unregistered options, instread of throwing.
          &lt;/li&gt;
          &lt;li&gt;
            Removed support for &amp;quot;implicit&amp;quot; (optional) values.
          &lt;/li&gt;
          &lt;li&gt;
            New customization method 'command_line_parser::extra_style_parser'. Unlike
            'additional_parser', allows the user to parse several tokens and return
            a vector of options, not just a single option.
          &lt;/li&gt;
          &lt;li&gt;
            Work with disabled exceptions.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;

        class, which provides dynamically-typed access to a set of property maps.
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/doc/libs/1_33_1/libs/python/doc/index.html&quot;&gt;Boost.Python&lt;/a&gt;:&lt;/span&gt;
        &lt;ul&gt;
          &lt;li&gt;
            Added support for docstrings on nonstatic properties.
          &lt;/li&gt;
          &lt;li&gt;
            We now export the client-provided docstrings for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;init&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;optional&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt; &lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt;
            and &lt;em&gt;XXX&lt;/em&gt;&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;_FUNCTION_OVERLOADS&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; for only the last overload.
          &lt;/li&gt;
          &lt;li&gt;
            Support for Embedded VC++ 4 and GCC-3.3 on MacOS added
          &lt;/li&gt;
          &lt;li&gt;
            Introduced better support for rvalue from-python conversions of shared_ptr.
          &lt;/li&gt;
          &lt;li&gt;
            Support for exposing &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;vector&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;T&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;*&amp;gt;&lt;/span&gt;&lt;/code&gt; with the indexing suite.
          &lt;/li&gt;
          &lt;li&gt;
            updated visual studio project build file.
          &lt;/li&gt;
          &lt;li&gt;
            Added search feature to the index page.
          &lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;

  Improved initialization for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;mersenne_twister&lt;/span&gt;&lt;/code&gt;,
        algorithm by Makoto Matsumoto and Takuji Nishimura, implemented for Boost
        by Jens Maurer.&lt;/p&gt;
  &lt;p&gt;Note: All test vectors for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;mersenne_twister&lt;/span&gt;&lt;/code&gt;s
        constructed or seeded without parameters or with a single &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;unsigned&lt;/span&gt;
        &lt;span class=&quot;keyword&quot;&gt;int&lt;/span&gt;&lt;/code&gt; parameter become invalid.&lt;/p&gt;

        &lt;ul&gt;
          &lt;li&gt;
            Rewritten front end parser now supports (?imsx-imsx) constructs, plus
            lookbehind assertions and conditional expressions.
          &lt;/li&gt;
          &lt;li&gt;
            Thin wrapper classes improve integration with MFC/ATL code.
          &lt;/li&gt;
          &lt;li&gt;
            Full (optional) Unicode support via the ICU library. Refer to the &lt;a href=&quot;/doc/libs/1_33_1/libs/regex/doc/history.html&quot;&gt;regex history page&lt;/a&gt;

      Boost is tested on a wide range of compilers and platforms. Since Boost libraries
      rely on modern C++ features not available in all compilers, not all Boost libraries
      will work with every compiler. The following compilers and platforms have been
      extensively tested with Boost, although many other compilers and platforms
      will work as well. For more information, see the &lt;a href=&quot;http://www.boost.org/regression/release/user/&quot;&gt;regression
      test results&lt;/a&gt;.

      The names of some the Boost.Build &lt;a href=&quot;/doc/libs/1_32_0/more/getting_started.html#Tools&quot;&gt;toolsets&lt;/a&gt;
      have been changed to remove the &amp;quot;&lt;tt&gt;.&lt;/tt&gt;&amp;quot; (dot) character
      and to fix some other naming inconsistencies. For example, &lt;tt&gt;vc7.1&lt;/tt&gt;
      toolset was renamed to become &lt;tt&gt;vc-7_1&lt;/tt&gt;. Please refer to the

          &lt;/li&gt;
          &lt;li&gt;
            Major interface changes and improvements, many of which are not backward
            compatible. Please refer to the &lt;a href=&quot;/doc/libs/1_32_0/libs/mpl/doc/tutorial/changes-in-boost-1-32-0.html&quot;&gt;1.32

        &lt;ul&gt;
          &lt;li&gt;
            Updated to use the Boost Software License.
          &lt;/li&gt;
          &lt;li&gt;
            a new, &lt;a href=&quot;/doc/libs/1_32_0/libs/python/doc/tutorial/doc/html/python/exposing.html#python.class_virtual_functions&quot;&gt;better
            method of wrapping classes with virtual functions&lt;/a&gt; has been implemented.
          &lt;/li&gt;
          &lt;li&gt;
            Support for the new Python Bool type, thanks to Daniel Holth.
          &lt;/li&gt;
          &lt;li&gt;
            Support for upcoming GCC symbol export control features have been folded
            in, thanks to Niall Douglas.
          &lt;/li&gt;
          &lt;li&gt;
            Improved support for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;std&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;auto_ptr&lt;/span&gt;&lt;/code&gt;-like
            types.
          &lt;/li&gt;
          &lt;li&gt;
            Components used by other libraries have been moved out of &lt;tt&gt;python/detail&lt;/tt&gt;
            and into &lt;tt&gt;boost/detail&lt;/tt&gt; to improve dependency relationships.
          &lt;/li&gt;
          &lt;li&gt;
            Miscellaneous bug fixes and compiler workarounds.
          &lt;/li&gt;

        deterministic slot ordering, permitting slots to be connected at the beginning
        or end of slot groups or the slot list itself. Combiners may safely have
        state and are accessible from the signal.

    &lt;li&gt;namespace names gets shorten; old one still supported till next
      release&lt;/li&gt;
    &lt;li&gt;added proper encoding of XML PCDATA&lt;/li&gt;
    &lt;li&gt;support for wide string comparison implemented&lt;/li&gt;

    &lt;p&gt;
      This release has been extensively tested on a variety of different compilers
      and platforms. It is known to contain no regressions against the previous reference
      release on the compilers and configurations tested. Please refer to the corresponding
      &lt;a href=&quot;http://www.meta-comm.com/engineering/boost-regression/1_32_0/index.html&quot;&gt;regression
      reports&lt;/a&gt; to see how well your compiler performs on the new Boost codebase.

      This release wouldn't have been possible without the dedicated effort of many,
      many members of the Boost community who generously contributed their outstanding
      expertise, time and energy to making it happen. For patches, bug fixes, troubleshooting,
      expert advice, and prompt responses to the release manager's requests we thank:

  &lt;div id=&quot;version_1_31_0.new_license&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;New License&lt;/span&gt;&lt;/h3&gt;
    &lt;p&gt;
      A unified &lt;a href=&quot;/doc/libs/1_31_0/more/license_info.html&quot;&gt;Boost Software
      License&lt;/a&gt; has been developed and will gradually replace the individual
      licenses for most Boost libraries. The new license offers better legal protection
      for both users and developers, and should speed user's legal reviews of Boost
      libraries. Dave Abrahams led the Boost effort to develop better licensing.
      The legal team was led by &lt;a href=&quot;http://cyber.law.harvard.edu/people/cabell/index.html&quot;&gt;Diane
      Cabell&lt;/a&gt;, Director, Clinical Programs, &lt;a href=&quot;http://cyber.law.harvard.edu&quot;&gt;Berkman
      Center for Internet &amp;amp; Society&lt;/a&gt;, Harvard Law School. &lt;a href=&quot;http://www.nixonpeabody.com/attorneys_detail1.asp?ID=121&quot;&gt;Devin
      Smith&lt;/a&gt;, attorney, &lt;a href=&quot;http://www.nixonpeabody.com/default.asp&quot;&gt;Nixon
      Peabody LLP&lt;/a&gt;, wrote the Boost License. Eva Chan, Harvard Law School,
      contributed analysis of issues and drafts of various legal documents.
    &lt;/p&gt;
    &lt;p&gt;
      Note: Many of the Boost libraries are still using earlier licenses, though
      all conform to the &lt;a href=&quot;/doc/libs/1_31_0/more/lib_guide.htm#license&quot;&gt;Boost
      License Requirements&lt;/a&gt;. After this release we will begin an effort to
      move toward uniform use of the new license.
    &lt;/p&gt;
  &lt;/div&gt;
  &lt;div id=&quot;version_1_31_0.build_and_installation&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;Build and Installation&lt;/span&gt;&lt;/h3&gt;
    &lt;ul&gt;
      &lt;li&gt;
        New &lt;a href=&quot;/doc/libs/1_31_0/more/getting_started.html&quot;&gt;Getting Started&lt;/a&gt;
        procedures ease download and installation, from Rene Rivera and others.
      &lt;/li&gt;
      &lt;li&gt;
        Improved support for libraries requiring &lt;a href=&quot;/doc/libs/1_31_0/more/separate_compilation.html&quot;&gt;separate
        compilation&lt;/a&gt;, from John Maddock and others.
      &lt;/li&gt;
    &lt;/ul&gt;
  &lt;/div&gt;
  &lt;div id=&quot;version_1_31_0.new_libraries&quot;&gt;

        inclusion of function template overloads, from Jaakko Jarvi, Jeremiah Willcock,
        and Andrew Lumsdaine. This is an important new technique which exploits the
        SFINAE (substitution-failure-is-not-an-error) principle.
      &lt;/li&gt;
      &lt;li&gt;
        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/doc/libs/1_31_0/libs/variant/index.html&quot;&gt;Variant Library&lt;/a&gt;:&lt;/span&gt; Safe,

        library has been deprecated and will be removed in a future release. Use
        &lt;a href=&quot;/doc/libs/1_31_0/libs/bind/bind.html&quot;&gt;Bind&lt;/a&gt; or &lt;a href=&quot;/doc/libs/1_31_0/libs/lambda/doc/index.html&quot;&gt;Lambda&lt;/a&gt; instead.

        improvements. See the Date Time Change History for details.
      &lt;/li&gt;
      &lt;li&gt;

  Several added functions, including improved checking for
        directory and file name portability.
      &lt;/li&gt;

        Library&lt;/a&gt;:&lt;/span&gt; Major version upgrade, with interface as proposed for the
        C++ library TR, including an improved &lt;tt&gt;iterator_adaptor&lt;/tt&gt;
        design plus several new components, from David Abrahams, Jeremy Siek, and
        Thomas Witt.
      &lt;/li&gt;

        &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/doc/libs/1_31_0/libs/multi_array/index.html&quot;&gt;MultiArray&lt;/a&gt;:&lt;/span&gt; The
        &lt;tt&gt;multi_array&lt;/tt&gt; class template now provides an element-preserving
        resize operation as well as default construction (see the &lt;a href=&quot;/doc/libs/1_31_0/libs/multi_array/doc/reference.html&quot;&gt;reference
        manual&lt;/a&gt; for more information).

            Suite&lt;/a&gt; added.
          &lt;/li&gt;
          &lt;li&gt;
            injected constructors and wrapped function objects.
          &lt;/li&gt;
          &lt;li&gt;
            wrapping static data members.

          &lt;/li&gt;
          &lt;li&gt;

          &lt;/li&gt;
          &lt;li&gt;
            Better error messages, including name demangling for GCC.
          &lt;/li&gt;
          &lt;li&gt;
            Simpler &lt;a href=&quot;/doc/libs/1_31_0/libs/python/doc/building.html&quot;&gt;build
            procedure&lt;/a&gt;.
          &lt;/li&gt;

        proposal&lt;/a&gt;, from Jens Maurer.

  &lt;ul&gt;
    &lt;li&gt;Multiple grammar start rules&lt;/li&gt;
    &lt;li&gt;Multiple Scanner rules (no more scanner business woes)&lt;/li&gt;
    &lt;li&gt;More dynamic parsers&lt;/li&gt;
    &lt;li&gt;Predefined actors&lt;/li&gt;
    &lt;li&gt;Numerous bug fixes and QOI stuff&lt;/li&gt;
    &lt;li&gt;&lt;em&gt;and more...&lt;/em&gt;&lt;/li&gt;
  &lt;/ul&gt;
  &lt;p&gt;
    Starting from Spirit v1.8.0, ill conforming compilers will no longer be
    supported. If you are still using one of these older compilers, please use
    Spirit v1.6.x. See [@http://spirit.sf.net Spirit's Site] for more details.

    &lt;li&gt;Free function template based test case&lt;/li&gt;
    &lt;li&gt;Custom exception translators support in execution monitor and
    register_exception_translator added for unit test framework&lt;/li&gt;
    &lt;li&gt;Added support for multi-module unit tests in automatic
    registration facility&lt;/li&gt;
    &lt;li&gt;Floating point comparison algorithm reworked (Is not backward
    compatible!!!)&lt;/li&gt;
    &lt;li&gt;Added support for custom users predicate returning both boolean
    result code and possibly error message&lt;/li&gt;

      Backported changes to the &lt;a href=&quot;/libs/config/config.htm&quot;&gt;config system&lt;/a&gt;,
      to better handle new compiler releases.
    &lt;/li&gt;

    &lt;li&gt;
      msvc-stlport and intel-win32-stlport toolsets now build static libraries with
      multithreading enabled, to be compatible with the STLPort builds.
    &lt;/li&gt;
    &lt;li&gt;
      intel-win32 toolset now handles &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;wchar_t&lt;/span&gt;&lt;/code&gt;
      correctly when intel is installed over msvc6.
    &lt;/li&gt;
    &lt;li&gt;
      Backported fixes from the main trunk which prevent errors building the &lt;a href=&quot;/libs/test/doc/index.html&quot;&gt;Boost.Test&lt;/a&gt; library in its default configuration.
    &lt;/li&gt;
    &lt;li&gt;
      Backported portability improvements for &lt;a href=&quot;/libs/utility/checked_delete.html&quot;&gt;checked_delete&lt;/a&gt;.
    &lt;/li&gt;
    &lt;li&gt;
      Locale support for metrowerks (requiring a statically-linked runtime) is more
      uniformly handled.
    &lt;/li&gt;
    &lt;li&gt;
      Backported &lt;a href=&quot;/libs/conversion/lexical_cast.htm&quot;&gt;conversion/lexical_cast&lt;/a&gt;'s
      &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;wchar_t&lt;/span&gt;&lt;/code&gt; fixes from the main trunk.
    &lt;/li&gt;
    &lt;li&gt;
      intel-linux-tools: added &lt;tt&gt;rt&lt;/tt&gt; to FINDLIBS in order to make
      the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;clock_gettime&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
      function available (backport of a patch in CVS HEAD).
    &lt;/li&gt;

      Withdrawn bug fix release, fixes for Lambda, Spirit, MPL, Function, Config,
      Format, Regex, Smart Pointers, Python
    &lt;/span&gt;&lt;/span&gt;</boostbook:purpose><description>&lt;div class=&quot;description&quot;&gt;
  
  
  &lt;p&gt;
    This release was withdrawn on the 12 Aug 2003.
  &lt;/p&gt;
  &lt;p&gt;
    Fixes were made to the following libraries: * The &lt;a href=&quot;/libs/lambda/doc/index.html&quot;&gt;Boost.Lambda&lt;/a&gt;
    ..library is now usable with gcc-2.95.2 * &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/spirit/index.html&quot;&gt;Boost.Spirit&lt;/a&gt;:&lt;/span&gt; 
  *
    Fixed. Using MSVC++6 (SP5), calling the assign action with a string value on
    parsers using the file_iterator will not work. * Fixed: using assign semantic
    action in a grammar with a multi_pass iterator adaptor applied to an std::istream_iterator
    resulted in a failure to compile under msvc 7.0. * Fixed: There is a bug in the
    &lt;tt&gt;range_run&amp;lt;CharT&amp;gt;::set(range&amp;lt;CharT&amp;gt; const&amp;amp; r)&lt;/tt&gt;
    function in &amp;quot;../boost/spirit/utility/impl/chset/range_run.ipp&amp;quot;. * Fixed:
    handling of trailing whitespace bug (ast_parse/pt_parse related) * Fixed: comment_p
    and end of data bug * Fixed: Most trailing space bug * Fixed: &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;chset&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;::&lt;/span&gt;&lt;span class=&quot;keyword&quot;&gt;operator&lt;/span&gt; &lt;span class=&quot;special&quot;&gt;~(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;range&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;)&lt;/span&gt;&lt;/code&gt;
    bug, &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;operator&lt;/span&gt; &lt;span class=&quot;special&quot;&gt;&amp;amp;(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;chset&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;,&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;range&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;)&lt;/span&gt;&lt;/code&gt;
    bug, &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;operator&lt;/span&gt; &lt;span class=&quot;special&quot;&gt;&amp;amp;(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;range&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;,&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;chset&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;)&lt;/span&gt;&lt;/code&gt;
    bug * Fixed: &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;impl&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;detach_clear&lt;/span&gt;&lt;/code&gt; bug * Fixed: mismatch closure
    return type bug * Fixed: &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;access_node_d&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;[]&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;access_match_d&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;[]&lt;/span&gt;&lt;/code&gt; iterator bugs * Fixed a bug regarding thread
    safety of Phoenix/Spirit closures. * The Boost Template &lt;a href=&quot;/libs/mpl/doc/index.html&quot;&gt;Metaprogramming
    Library (MPL)&lt;/a&gt;'s ..typeof implementation is now compatible with Metrowerks
    CodeWarrior Pro8. * &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/function/index.html&quot;&gt;Boost.Function&lt;/a&gt;:&lt;/span&gt; workaround
    for the new Borland patch (version 0x564) and MSVC++ .NET 2003. * &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/config/index.html&quot;&gt;Boost.Config&lt;/a&gt;&lt;/span&gt;, &lt;a href=&quot;/libs/format/doc/format.html&quot;&gt;Boost.Format&lt;/a&gt;,
    and &lt;a href=&quot;/libs/regex/index.html&quot;&gt;Boost.Regex&lt;/a&gt; ..have been adjusted
    to avoid warnings with GCC-3.3, and Boost.Format also now works with string types
    other than &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;std&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;string&lt;/span&gt;&lt;/code&gt;. * &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/smart_ptr/index.html&quot;&gt;Smart
    Pointers&lt;/a&gt;:&lt;/span&gt; 
  * &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;checked_delete&lt;/span&gt;&lt;/code&gt;
    now works on more platforms * Compatibility with the SunPro compiler * Added
    missing &lt;code&gt;&lt;span class=&quot;preprocessor&quot;&gt;#include&lt;/span&gt;&lt;/code&gt;s. * &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/python/index.html&quot;&gt;Boost.Python&lt;/a&gt;:&lt;/span&gt; 
  * warning suppression for
    finicky compilers * fixed a crashing bug in the &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;raw_function&lt;/span&gt;&lt;/code&gt;
    facility when no keyword arguments were passed. * Improved conversion of NULL
    &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;shared_ptr&lt;/span&gt;&lt;/code&gt;s to Python.

      2 is released, from Dave Abrahams and others. This is a major rewrite which
      works on many more compilers and platforms, with a completely new interface
      and lots of new features. Boost.Python v2 requires Python 2.2 or later.
    &lt;/li&gt;
    &lt;li&gt;

      &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/preprocessor/doc/index.html&quot;&gt;Preprocessor Library&lt;/a&gt;:&lt;/span&gt;

  Updated
      use of iterator adaptors. Changed &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;operator&lt;/span&gt;
      &lt;span class=&quot;special&quot;&gt;==&lt;/span&gt;&lt;/code&gt; for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;adjacency_list&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;edge_descriptor&lt;/span&gt;&lt;/code&gt;
      to improve semantics for multigraphs. Moved &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;adjacency_iterator_generator&lt;/span&gt;&lt;/code&gt;
      from namespace &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;detail&lt;/span&gt;&lt;/code&gt; to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;boost&lt;/span&gt;&lt;/code&gt; and added &lt;a href=&quot;/libs/graph/doc/adjacency_iterator.html&quot;&gt;documentation&lt;/a&gt;.

      better matching graph literature terminology. Cleaned up interface of &lt;a href=&quot;/libs/graph/doc/connected_components.html&quot;&gt;&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;connected_components&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;&lt;/a&gt; and created separate &lt;a href=&quot;/libs/graph/doc/strong_components.html&quot;&gt;&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;strong_components&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;&lt;/a&gt;
      function using Tarjan's more efficient algorithm. Fixed documentation figures
      for &lt;a href=&quot;/libs/graph/doc/adjacency_list.html&quot;&gt;&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;adjacency_list&lt;/span&gt;&lt;/code&gt;&lt;/a&gt;

      algorithm.

      &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/python/doc/index.html&quot;&gt;Python Library&lt;/a&gt;&lt;/span&gt; upgraded.
      Better compatibility with Python 2.0, NULL pointers and smart-pointers get
      converted to/from python None, massive documentation review/revision.
    &lt;/li&gt;
    &lt;li&gt;

      operators.hpp&lt;/a&gt;, together with an iterator test program. This header
      is maturing into something really useful for building arithmetic or iterator
      user-defined types, so look it over even if you browsed one of the earlier
      versions.
    &lt;/p&gt;
  &lt;/div&gt;
  &lt;div id=&quot;old_versions.11_dec_1999&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;11 Dec 1999&lt;/span&gt;&lt;/h3&gt;
    &lt;p&gt;
      Added next() and prior() to &lt;a href=&quot;/libs/utility/utility.htm&quot;&gt;header utility.hpp&lt;/a&gt;.
    &lt;/p&gt;
  &lt;/div&gt;
  &lt;div id=&quot;old_versions.8_dec_1999&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;8 Dec 1999&lt;/span&gt;&lt;/h3&gt;
    &lt;p&gt;
      Minor improvements to the &lt;a href=&quot;/libs/smart_ptr/index.html&quot;&gt;smart pointer&lt;/a&gt;
      library: &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;operator&lt;/span&gt; &lt;span class=&quot;special&quot;&gt;==&lt;/span&gt;&lt;/code&gt;,
      &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;operator&lt;/span&gt; &lt;span class=&quot;special&quot;&gt;!=&lt;/span&gt;&lt;/code&gt;,
      and specializations for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;std&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;swap&lt;/span&gt;&lt;/code&gt; and
      &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;std&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;less&lt;/span&gt;&lt;/code&gt; now provided.
    &lt;/p&gt;
  &lt;/div&gt;
  &lt;div id=&quot;old_versions.18_nov_1999&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;18 Nov 1999&lt;/span&gt;&lt;/h3&gt;
    &lt;p&gt;
      Minor improvements made to the &lt;a href=&quot;/libs/utility/operators.htm&quot;&gt;Operator
      templates&lt;/a&gt;.
    &lt;/p&gt;
  &lt;/div&gt;
  &lt;div id=&quot;old_versions.15_nov_1999&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;15 Nov 1999&lt;/span&gt;&lt;/h3&gt;
    &lt;p&gt;
      &lt;a href=&quot;/libs/utility/operators.htm&quot;&gt;Operator templates&lt;/a&gt; have been
      added to the &lt;a href=&quot;/libs/utility/index.html&quot;&gt;utility&lt;/a&gt; library.
    &lt;/p&gt;
  &lt;/div&gt;
  &lt;div id=&quot;old_versions.11_oct_1999&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;11 Oct 1999&lt;/span&gt;&lt;/h3&gt;
    &lt;p&gt;
      Minor &lt;a href=&quot;/libs/smart_ptr/index.html&quot;&gt;smart pointer&lt;/a&gt; library
      and &lt;a href=&quot;/boost/config.hpp&quot;&gt;config.hpp&lt;/a&gt; changes to improve portability.
    &lt;/p&gt;
  &lt;/div&gt;
  &lt;div id=&quot;old_versions.26_sep_1999&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;26 Sep 1999&lt;/span&gt;&lt;/h3&gt;
    &lt;p&gt;
      Minor updates to several libraries: * &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;polymorphic_downcast&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt; in the &lt;a href=&quot;/libs/utility/index.html&quot;&gt;utility&lt;/a&gt;
      library &lt;a href=&quot;/boost/cast.hpp&quot;&gt;cast.hpp&lt;/a&gt; header now works for
      multiple inheritance cases. * &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;shared_ptr&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;shared_array&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt; &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;swap&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt; functions added in the &lt;a href=&quot;/libs/smart_ptr/index.html&quot;&gt;smart
      pointer&lt;/a&gt; library. * &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/boost/timer.hpp&quot;&gt;timer.hpp&lt;/a&gt;&lt;/span&gt; &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;elapsed_max&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
      and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;elapsed_min&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
      functions added to the &lt;a href=&quot;/libs/timer/index.html&quot;&gt;timer&lt;/a&gt; library.
      * &lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;/libs/integer/index.html&quot;&gt;integer&lt;/a&gt;&lt;/span&gt; library bin_ubin.hpp
      changes to eliminate compiler warning messages. * &lt;a href=&quot;/boost/config.hpp&quot;&gt;config.hpp&lt;/a&gt;
      minor changes to aid library developers. No impact on library users.
    &lt;/p&gt;
  &lt;/div&gt;
  &lt;div id=&quot;old_versions.3_sep_1999&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;3 Sep 1999&lt;/span&gt;&lt;/h3&gt;
    &lt;p&gt;
      The cast functions in the &lt;a href=&quot;/libs/utility/index.html&quot;&gt;utility&lt;/a&gt;
      library were considerably simplified.
    &lt;/p&gt;
  &lt;/div&gt;
  &lt;div id=&quot;old_versions.1_sep_1999&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;1 Sep 1999&lt;/span&gt;&lt;/h3&gt;
    &lt;p&gt;
      The cast functions initially in &lt;a href=&quot;/boost/utility.hpp&quot;&gt;utility.hpp&lt;/a&gt;
      have been moved to &lt;a href=&quot;/boost/cast.hpp&quot;&gt;cast.hpp&lt;/a&gt;, still in
      the &lt;a href=&quot;/libs/utility/index.html&quot;&gt;utility&lt;/a&gt; library.
    &lt;/p&gt;
  &lt;/div&gt;
  &lt;div id=&quot;old_versions.1_sep_1999&quot;&gt;
    &lt;h3&gt;&lt;span class=&quot;link&quot;&gt;1 Sep 1999&lt;/span&gt;&lt;/h3&gt;
    &lt;p&gt;
      The category &amp;quot;Experimental&amp;quot; has been added to the &lt;a href=&quot;/libs/libraries.htm&quot;&gt;library&lt;/a&gt;
      page. The &lt;a href=&quot;/libs/integer/index.html&quot;&gt;integer&lt;/a&gt; library is
      the first entry.
    &lt;/p&gt;
  &lt;/div&gt;
  &lt;p&gt;
    ...And the remainder are lost to the mists of time (for now, anyway)....
  &lt;/p&gt;
