&lt;div id=&quot;version_1_56_0.modularization&quot;&gt;
&lt;h3&gt;&lt;span class=&quot;link&quot;&gt;Modularization&lt;/span&gt;&lt;/h3&gt;
&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;
&lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/doc/libs/1_56_0_b1/libs/assert/&quot;&gt;Assert&lt;/a&gt;:&lt;/span&gt;
Customizable assert macros.
Maintained by Peter Dimov.
&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/doc/libs/1_56_0_b1/libs/core/&quot;&gt;Core&lt;/a&gt;:&lt;/span&gt;
Core utilities used by other
libraries, with minimal dependencies. Maintained by Peter Dimov, Glen Fernandes
and Andrey Semashev.
&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/doc/libs/1_56_0_b1/libs/lexical_cast/&quot;&gt;Lexical_Cast&lt;/a&gt;:&lt;/span&gt;
General literal
text conversions, such as an int represented a string, or vice-versa, from
Kevlin Henney.
&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/doc/libs/1_56_0_b1/libs/throw_exception/&quot;&gt;Throw_Exception&lt;/a&gt;:&lt;/span&gt;
A common
infrastructure for throwing exceptions from Boost libraries, from Emil
Dotchevski.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;span class=&quot;library&quot;&gt;Winapi:&lt;/span&gt;
Windows API declarations without &amp;lt;windows.h&amp;gt;, for internal
Boost use.
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;
&lt;div id=&quot;version_1_56_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/doc/libs/1_56_0_b1/libs/align/&quot;&gt;Align&lt;/a&gt;:&lt;/span&gt;
Memory alignment functions,
allocators, and adaptors, from Glen Fernandes.
&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/doc/libs/1_56_0_b1/libs/type_index/&quot;&gt;Type_Index&lt;/a&gt;:&lt;/span&gt;
Runtime/Compile
time copyable type info, from Antony Polukhin.
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;
&lt;div id=&quot;version_1_56_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/doc/libs/1_56_0_b1/libs/accumulators/&quot;&gt;Acumulators&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
New accumulators &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;rolling_variance&lt;/span&gt;&lt;/code&gt;
and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;rolling_moment&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;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/doc/libs/1_56_0_b1/libs/any/&quot;&gt;Any&lt;/a&gt;:&lt;/span&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;li&gt;
&lt;div&gt;
&lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/doc/libs/1_56_0_b1/libs/asio/&quot;&gt;Asio&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;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/doc/libs/1_56_0_b1/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/doc/libs/1_56_0_b1/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;
Fixed compilation for SPARCv9 target. (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9446&quot;&gt;#9446&lt;/a&gt;)
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed compilation for PowerPC target. (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9447&quot;&gt;#9447&lt;/a&gt;)
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed several compatibility problems with Clang on x86 and x86-64.
(&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9610&quot;&gt;#9610&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9842&quot;&gt;#9842&lt;/a&gt;)
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Removed specialized code for Windows on IA64 platform.
&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/doc/libs/1_56_0_b1/libs/circular_buffer/&quot;&gt;Circular Buffer&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/9970&quot;&gt;#9970&lt;/a&gt;,&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9334&quot;&gt;#9334&lt;/a&gt; Support for the C++11 allocator model.
&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;li&gt;
&lt;div&gt;
&lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/doc/libs/1_56_0_b1/libs/concept_check/&quot;&gt;Concept Check&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Fewer warnings (includes &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5012&quot;&gt;#5012&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/doc/libs/1_56_0_b1/libs/container/&quot;&gt;Container&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Added DlMalloc-based Extended Allocators.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Improved configurability of tree-based ordered associative containers.
AVL, Scapegoat and Splay trees are now available to implement &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;set&lt;/span&gt;&lt;/code&gt;, &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;multiset&lt;/span&gt;&lt;/code&gt;,
&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;map&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;multimap&lt;/span&gt;&lt;/code&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed bugs:
&lt;ul&gt;

&lt;li&gt;
&lt;div&gt;
Additional functionality
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
New algorithm buffer for inflating/deflating geometries (buffer
itself already existed but that was only to enlarge a box)
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
New algorithm remove_spikes, algorithm to remove spikes from
a ring, polygon or multi_polygon.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
New algorithm point_on_surface, generating a point lying on
the surface (interior) of the polygon
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
New algorithm is_simple, returning true if a geometry is simple
according to the OGC standard
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
New algorithm is_valid, returning true if a geometry is valid
according to the OGC standard
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
New algorithm crosses for checking this spatial relation according
to the OGC standard
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
The set operation algorithms (difference, intersection, sym_difference
and union_) now support as input pairs of pointlike or linear
geometries
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
The distance and comparable_distance algorithms now support
all pairs of geometry combinations
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
The spatial relations which didn't support it (covered_by,
touches, within, etc.) now support as input linear and/or areal
geometries
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
The support for boost::variants as input geometries in various
algorithms
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
The rtree support for indexing segments
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
The rtree nearest() predicate support for arbitrary geometries
&lt;/div&gt;
&lt;/li&gt;

&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&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;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;div&gt;
Fixed bugs:
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8468&quot;&gt;#8468:
Compile error on visual studio 2010/2012 using vector with
custom allocator and aligned types&lt;/a&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9332&quot;&gt;#9332:

&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9650&quot;&gt;#9650:
&lt;em&gt;&amp;quot;intrusive list with stateful value traits&amp;quot;&lt;/em&gt;&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9746&quot;&gt;#9746:
Modern Sun CC compiler detects error in intrusive library header&lt;/a&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9940&quot;&gt;#9940:
bad bug in intrusive list with safe_link (or auto_unlink) hooks&lt;/a&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9948&quot;&gt;#9948:
remove use of const_cast in intrusive containers&lt;/a&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9949&quot;&gt;#9949:
clear header node hooks upon intrusive container destruction&lt;/a&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9961&quot;&gt;#9961:
tests for hooks not derived frorm generic_hook&lt;/a&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Optimized tree rebalancing code to avoid redundant assignments.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Added 64 bit prime values for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;suggested_upper_bucket_count&lt;/span&gt;&lt;/code&gt;/&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;suggested_lower_bucket_count&lt;/span&gt;&lt;/code&gt; in
64 bit platforms.
&lt;/div&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;/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/doc/libs/1_56_0_b1/libs/lexical_cast/&quot;&gt;Lexical Cast&lt;/a&gt;:&lt;/span&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
to be Default Constructable (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6700&quot;&gt;#6700&lt;/a&gt;).
&lt;/div&gt;
&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;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Code was changed to produce a smaller binaries and simplify compiler's
work (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9046&quot;&gt;#9046&lt;/a&gt;).
&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;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/doc/libs/1_56_0_b1/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/doc/libs/1_56_0_b1/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/doc/libs/1_56_0_b1/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;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fix round and trunc functions so they can be used with integer arguments,
see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/10066&quot;&gt;#10066&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fix Halley iteration to handle zero derivative (with non-zero second
derivative), see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/10046&quot;&gt;#10046&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fix Geometric distribution use of Policies, see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9833&quot;&gt;#9833&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fix corner cases in the negative binomial distribution, see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9834&quot;&gt;#9834&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fix compilation failures on Mac OS.
&lt;/div&gt;
&lt;/li&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;/div&gt;
&lt;/li&gt;
&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;
parameter in root finding code better, see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9225&quot;&gt;#9225&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Add option to explicitly enable/disable use of __float128 in constants
code, see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9240&quot;&gt;#9240&lt;/a&gt;.
&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;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9672&quot;&gt;#9672 PDF
and CDF of a Laplace distribution throwing domain_error&lt;/a&gt; Random
variate can now be infinite.
&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),
see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9712&quot;&gt;#9712&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;

&lt;li&gt;
&lt;div&gt;
Added &lt;code&gt;BOOST_MOVE_RET&lt;/code&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/9482&quot;&gt;#9482:
&lt;em&gt;&amp;quot;MSVC macros not undefined in boost/move/detail/config_end.hpp&amp;quot;&lt;/em&gt;&lt;/a&gt;,
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9045&quot;&gt;#9045:

&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9212&quot;&gt;#9212&lt;/a&gt; Broken links to C++ standard papers
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8368&quot;&gt;#8368&lt;/a&gt; GCC -Wundef warning about BOOST_MULTI_ARRAY_NO_GENERATORS
in multi_array

&lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/doc/libs/1_56_0_b1/libs/multi_index/index.html&quot;&gt;Multi-index Containers&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
The &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;erase&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;iterator&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)&lt;/span&gt;&lt;/code&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/doc/libs/1_56_0_b1/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;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Maintenance fixes.
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;

&lt;ul&gt;
&lt;li&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/doc/libs/1_56_0_b1/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/doc/libs/1_56_0_b1/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;/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;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;/li&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;div&gt;
Columns in the &lt;code&gt;&lt;span class=&quot;special&quot;&gt;--&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;help&lt;/span&gt;&lt;/code&gt;
output are now aligned across all option groups (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6114&quot;&gt;#6114&lt;/a&gt;).
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Option names with dashes are no longer truncated in error messages
(&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8009&quot;&gt;#8009&lt;/a&gt;).
&lt;/div&gt;

of &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;mark_count&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
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;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;/div&gt;
&lt;/li&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;.
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Updated the overloads of &lt;a href=&quot;http://www.boost.org/doc/libs/1_56_0_b1/libs/smart_ptr/make_shared_array.html&quot;&gt;make_shared&lt;/a&gt;
and &lt;a href=&quot;http://www.boost.org/doc/libs/1_56_0_b1/libs/smart_ptr/make_shared_array.html&quot;&gt;allocate_shared&lt;/a&gt;
of array types (&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;) to conform to the specification
in C++ standard paper &lt;a href=&quot;http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n3939.html&quot;&gt;N3939&lt;/a&gt;
and significantly reduced the spatial overhead of the internal bookkeeping
structures.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Updated the implementations of make_shared and allocate_shared for
scalar types and array types, respectively, to resolve C++ standard
library defect report &lt;a href=&quot;http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-active.html#2070&quot;&gt;#2070&lt;/a&gt;.

&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
This library is now deprecated.
&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/doc/libs/1_56_0_b1/libs/tti/&quot;&gt;TTI&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Ticket &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9441&quot;&gt;#9441&lt;/a&gt;: Added better support for Sun Solaris Studio C++
compiler.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Ticket &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9444&quot;&gt;#9444&lt;/a&gt;: Handle all situations where the enclosing class
is not a class type.
&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/doc/libs/1_56_0_b1/libs/unordered/&quot;&gt;Unordered&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Minor documentation and warning fixes (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9377&quot;&gt;#9377&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9719&quot;&gt;#9719&lt;/a&gt;).
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Always use prime number of buckets for integers. Fixes performance
regression when inserting consecutive integers (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9282&quot;&gt;#9282&lt;/a&gt;).
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Only construct elements using allocators, as specified in C++11 standard.
&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/doc/libs/1_56_0_b1/libs/utility/index.html&quot;&gt;Utility&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Some components were moved to the new Boost.Core library.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;empty_deleter&lt;/span&gt;&lt;/code&gt; is
deprecated in favor of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;null_deleter&lt;/span&gt;&lt;/code&gt;
from Boost.Core. &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;empty_deleter&lt;/span&gt;&lt;/code&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;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;base_from_member&lt;/span&gt;&lt;/code&gt;
utility now supports lvalue reference member types. (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7577&quot;&gt;#7577&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/doc/libs/1_56_0_b1/libs/uuid/index.html&quot;&gt;UUID&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Added basic support for C++11 features.
&lt;/div&gt;
&lt;/li&gt;
&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/doc/libs/1_56_0_b1/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;/div&gt;
&lt;/li&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;li&gt;
&lt;div&gt;
&lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/doc/libs/1_56_0_b1/libs/variant/&quot;&gt;Variant&lt;/a&gt;:&lt;/span&gt;
&lt;ul&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/doc/libs/1_56_0_b1/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/doc/libs/1_56_0_b1/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/doc/libs/1_56_0_b1/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;div&gt;
&lt;a href=&quot;http://www.boost.org/doc/libs/1_56_0_b1/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;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;
&lt;div id=&quot;version_1_56_0.compilers_tested&quot;&gt;
&lt;h3&gt;&lt;span class=&quot;link&quot;&gt;Compilers Tested&lt;/span&gt;&lt;/h3&gt;
&lt;p&gt;

Support was removed from &lt;a href=&quot;http://www.boost.org/libs/config/&quot;&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=&quot;version_1_55_0.known_bugs&quot;&gt;
&lt;h3&gt;&lt;span class=&quot;link&quot;&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=&quot;identifier&quot;&gt;has_member_function_callable_with&lt;/span&gt;&lt;/code&gt;
from Boost.Container's &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;allocator_traits&lt;/span&gt;&lt;/code&gt;
causes a compile error (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9332&quot;&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=&quot;identifier&quot;&gt;ex_scoped_thread&lt;/span&gt;&lt;/code&gt;
compile fails (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9333&quot;&gt;#9333&lt;/a&gt;).
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;

set of compiler, architecture, operating system, library, and other version
numbers from the information it can gather of C, C++, Objective C, and
Objective C++ predefined macros or those defined in generally available

&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8262&quot;&gt;#8262&lt;/a&gt; Rename &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;average&lt;/span&gt;&lt;/code&gt;
to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;fdiv&lt;/span&gt;&lt;/code&gt;.

&lt;div&gt;

across modules &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8751&quot;&gt;#8751&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;clear&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;&lt;/code&gt;
member function.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Added missing &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_NOEXCEPT&lt;/span&gt;&lt;/code&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed issue with const rvalues &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9215&quot;&gt;#9215&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/asio/&quot;&gt;Asio&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&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=&quot;identifier&quot;&gt;io_service&lt;/span&gt;&lt;/code&gt;,
&lt;code&gt;&lt;span class=&quot;identifier&quot;&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;
&lt;div&gt;
The &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;cancel&lt;/span&gt;&lt;span class=&quot;special&quot;&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=&quot;identifier&quot;&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=&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;no_delay&lt;/span&gt;&lt;/code&gt; and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;socket_base&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&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 &amp;quot;80&amp;quot; rather than &amp;quot;http&amp;quot;.
&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=&quot;identifier&quot;&gt;async_connect&lt;/span&gt;&lt;/code&gt;
were not correctly propagated through to the completion handler (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8795&quot;&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=&quot;identifier&quot;&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=&quot;https://svn.boost.org/trac/boost/ticket/8933&quot;&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=&quot;https://svn.boost.org/trac/boost/ticket/8808&quot;&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=&quot;https://svn.boost.org/trac/boost/ticket/8752&quot;&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=&quot;identifier&quot;&gt;async_wait&lt;/span&gt;&lt;/code&gt;
on a signal that is already raised (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8738&quot;&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=&quot;https://svn.boost.org/trac/boost/ticket/8980&quot;&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=&quot;https://svn.boost.org/trac/boost/ticket/8624&quot;&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=&quot;identifier&quot;&gt;async_write_at&lt;/span&gt;&lt;/code&gt; operations (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8669&quot;&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=&quot;identifier&quot;&gt;HANDLE&lt;/span&gt;&lt;/code&gt;
backend to treat &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;ERROR_MORE_DATA&lt;/span&gt;&lt;/code&gt;
as a non-fatal error when returned by &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;GetOverlappedResult&lt;/span&gt;&lt;/code&gt;
for a synchronous read (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8722&quot;&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=&quot;identifier&quot;&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=&quot;identifier&quot;&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=&quot;identifier&quot;&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=&quot;https://svn.boost.org/trac/boost/ticket/9000&quot;&gt;#9000&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9001&quot;&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=&quot;https://svn.boost.org/trac/boost/ticket/8959&quot;&gt;#8959&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;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=&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;min&lt;/span&gt;&lt;/code&gt;
in the Windows IOCP backend to avoid a dependency on the &lt;code&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;algorithm&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;gt;&lt;/span&gt;&lt;/code&gt; header (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8758&quot;&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=&quot;https://svn.boost.org/trac/boost/ticket/8347&quot;&gt;#8347&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8950&quot;&gt;#8950&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8953&quot;&gt;#8953&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8965&quot;&gt;#8965&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8997&quot;&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=&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;
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=&quot;identifier&quot;&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=&quot;identifier&quot;&gt;atomic&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt; based on GCC &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;__atomic&lt;/span&gt;&lt;span class=&quot;special&quot;&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;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;em&gt;Fixed Bugs:&lt;/em&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/7868&quot;&gt;#7868&lt;/a&gt;
&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;chrono_io&lt;/span&gt;&lt;/code&gt; parses
time incorrectly (1.53 and 1.52)
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/9028&quot;&gt;#9028&lt;/a&gt;
Typo 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;chrono&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;stopwatches&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;formatters&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;base_formatter&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;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/9147&quot;&gt;#9147&lt;/a&gt;
uninitialized &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;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=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/circular_buffer/&quot;&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=&quot;https://svn.boost.org/trac/boost/ticket/7888&quot;&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=&quot;http://svn.boost.org/trac/boost/ticket/5362&quot;&gt;#5362&lt;/a&gt;
circular_buffer does not compile with &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_NO_EXCEPTIONS&lt;/span&gt;&lt;/code&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/7025&quot;&gt;#7025&lt;/a&gt;
circular buffer reports warning: &amp;quot; type qualifiers ignored on
function return type&amp;quot; while compile.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/7950&quot;&gt;#7950&lt;/a&gt;
Eliminate W4-warnings under VS2005 - warning C4913: user defined
binary operator ',' exists but no overload could convert all operands,
default built-in binary operator ',' used.
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
&lt;strong&gt;Breaking change:&lt;/strong&gt; Removed support
for some older compilers. The new minimum compiler versions are:
&lt;/div&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;

&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;div&gt;
Other compilers are unchanged.
&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/container/&quot;&gt;Container&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Implemented &lt;span class=&quot;link&quot;&gt;SCARY

&lt;li&gt;
&lt;div&gt;
&lt;em&gt;Additional functionality&lt;/em&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Added centroid for segment type
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Added intersects() and disjoints() for Segment-Box and Linestring-Box
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Added rtree creation using packing algorithm
&lt;/div&gt;

&lt;em&gt;Bugfixes&lt;/em&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
In some cases .back() or .clear() was called, violating the
usage of Concepts. Fixed for the reported cases
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;em&gt;Solved tickets&lt;/em&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6958&quot;&gt;6958&lt;/a&gt;
Intersection generates self-intersection. Caused by spike,
fixed
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8364&quot;&gt;8364&lt;/a&gt;
Invalid input exception, caused by spikes in previous steps,
fixed
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8365&quot;&gt;8365&lt;/a&gt;
Invalid input exception, caused by spikes in previous steps,
fixed
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8969&quot;&gt;8969&lt;/a&gt;
boost::geometry::model::point single argument constructor should
be explicit
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8825&quot;&gt;8825&lt;/a&gt;
Patch adding member variable documentation to doxygen_xml2qbk
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8652&quot;&gt;8652&lt;/a&gt;
Intersection fails for triangle-triangle intersection. Caused
by spike, fixed
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9047&quot;&gt;9047&lt;/a&gt;
Boost files that include themselves (strategies/intersection.hpp),
fixed
&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/graph/index.html&quot;&gt;Graph&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
&lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;void&lt;/span&gt;&lt;/code&gt; is no longer allowed
as a bundled property type (for example, in the VertexProperties
template parameters to graph types); it did not work reliably before,
but a static assertion now forbids it entirely. 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;no_property&lt;/span&gt;&lt;/code&gt; instead.
&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;finish_edge&lt;/span&gt;&lt;/code&gt;
visitor event point in depth-first search; the change should be backward-compatible
with visitors that do not have that member function.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Disabled building of tests on Sun compiler.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Multiple source vertices are supported in non-named-parameter versions
of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;breadth_first_visit&lt;/span&gt;&lt;/code&gt;,
&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;breadth_first_search&lt;/span&gt;&lt;/code&gt;,
&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;dijkstra_shortest_paths&lt;/span&gt;&lt;/code&gt;,
and &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;dijkstra_shortest_paths_no_init&lt;/span&gt;&lt;/code&gt;.
This feature is not yet documented; to use it, replace the single
parameter for the source vertex in each of these functions by two
input iterators of the same type containing the source vertices to
use.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;

Added Hawick circuits algorithm; contributed by Louis Dionne.
&lt;/div&gt;

Added edge coloring algorithm; contributed by Maciej Piechotka.
&lt;/div&gt;

&lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/intrusive/&quot;&gt;Intrusive&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
&lt;strong&gt;Source breaking&lt;/strong&gt;: Deprecated &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;xxx_dont_splay&lt;/span&gt;&lt;/code&gt; functions from splay
containers. Deprecated &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;splay_set_hook&lt;/span&gt;&lt;/code&gt;
from splay containers, use &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;bs_set_hook&lt;/span&gt;&lt;/code&gt;
instead. Both will be removed in Boost 1.56.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;strong&gt;ABI breaking&lt;/strong&gt;: Hash containers' end
iterator was implemented pointing to one-past the end of the bucket
array (see &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8698&quot;&gt;#8698&lt;/a&gt;)
causing severe bugs when values to be inserted where allocated next
to the bucket array. End iterator implementation was changed to point
to the beginning of the bucket array.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
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;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Implemented &lt;span class=&quot;link&quot;&gt;SCARY iterators&lt;/span&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/conversion/lexical_cast.htm&quot;&gt;Lexical cast&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
&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;bad_alloc&lt;/span&gt;&lt;/code&gt; exceptions are now are
not converted 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;bad_lexical_cast&lt;/span&gt;&lt;/code&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8966&quot;&gt;#8966&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Added static assert that checks 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;numeric_limits&lt;/span&gt;&lt;/code&gt;
specializations if they are required for conversion. Use &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_HAS_INT128&lt;/span&gt;&lt;/code&gt; for detecting
128 bit integers support &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8790&quot;&gt;#8790&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Documentation improved and more usage examples added.
&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/log/&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;
Added a new configuration macro &lt;code&gt;&lt;span class=&quot;identifier&quot;&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=&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;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;explicit_operator_bool&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;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;empty_deleter&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;.
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;/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;timer&lt;/span&gt;&lt;/code&gt;
attribute generating incorrect time readings on Windows on
heavy thread contention when &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;QueryPerformanceCounter&lt;/span&gt;&lt;/code&gt;
API was used.
&lt;/div&gt;
&lt;/li&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;
&lt;li&gt;
&lt;div&gt;
Fixed thread id formatting discrepancies between the default
sink and formatters.
&lt;/div&gt;
&lt;/li&gt;

&lt;div&gt;
Fixed PGI compilation issue &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8333&quot;&gt;#8333&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed PGI constant value initialization issue that caused erf to
generate incorrect results &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8621&quot;&gt;#8621&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Prevent macro expansion of some C99 macros that are also C++ functions
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8732&quot;&gt;#8732&lt;/a&gt;
and &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8733&quot;&gt;#8733&lt;/a&gt;..
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed Student's T distribution to behave correctly with huge degrees
of freedom (larger than the largest representable integer) &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8837&quot;&gt;#8837&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Make some core functions usable with &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; even when the platform
has no standard library &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; support &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8940&quot;&gt;#8940&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fix error handling of distributions to catch invalid scale and location
parameters when the random variable is infinite &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9042&quot;&gt;#9042&lt;/a&gt;
and &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9126&quot;&gt;#9126&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Add workaround for broken &amp;lt;tuple&amp;gt; in Intel C++ 14 &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/9087&quot;&gt;#9087&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Improve consistency of argument reduction in the elliptic integrals

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

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

&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Fixed bugs &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7952&quot;&gt;#7952&lt;/a&gt;,
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8764&quot;&gt;#8764&lt;/a&gt;,

&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
New feature: interrupt states now support a sequence of events to
end the interruption.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed Trac &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8686&quot;&gt;#8686&lt;/a&gt;.
&lt;/div&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Added support for Boost.Serialization.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Suppressed some GCC warnings. See &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8872&quot;&gt;8872&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed bug in pow for large integer arguments. See &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8809&quot;&gt;8809&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;

&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed bug in fixed precision cpp_int IO code that causes conversion
to string to fail when the bit count is very small (less than CHAR_BIT).
See &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8745&quot;&gt;8745&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed bug in cpp_int that causes left shift to fail when a fixed
precision type would overflow. See &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8741&quot;&gt;8741&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed some cosmetic warnings from cpp_int. See &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8748&quot;&gt;8748&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed calls to functions which are required to be macros in C99.
See &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8732&quot;&gt;8732&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed bug that causes construction from INT_MIN, LONG_MIN etc to
fail in cpp_int. See &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8711&quot;&gt;8711&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/multi_index/index.html&quot;&gt;Multi-index Containers&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Boost.MultiIndex has been brought to a higher level of compliance
with C++11.
&lt;/div&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;multi_index_container&lt;/span&gt;&lt;/code&gt;
is now efficiently movable.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Initializer lists supported.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Emplace functions provided.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Non-copyable elements (such as &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;unique_ptr&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;) supported. This includes
insertion of a range [&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;first&lt;/span&gt;&lt;/code&gt;,&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;last&lt;/span&gt;&lt;/code&gt;) where the iterators point
to a type that is convertible to that of the element: no copy
construction happens in the process.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Random access indices provide &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;shrink_to_fit&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;
Refer to the &lt;a href=&quot;http://www.boost.org/libs/multi_index/doc/compiler_specifics.html&quot;&gt;compiler

&lt;div&gt;
Replaced calls to deprecated MPI functions

&lt;li&gt;
&lt;div&gt;
Added support for multi-threaded initialization

Updated CGAL part of the Voronoi benchmark with patches from Sebastien
Loriot. Updated documentation.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Added polygon decomposition capability to polygon_90_set_data container
(patch from Intel). Updated documentation.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Bugs fixed from Trac: &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8197&quot;&gt;#8197&lt;/a&gt;.

dynamic_properties objects can now be built by non-destructively
chaining &lt;code&gt;&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;property&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;name&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;,&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;pm&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)&lt;/span&gt;&lt;/code&gt; calls. Example:
&lt;/div&gt;
&lt;pre&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;dynamic_properties&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&lt;/span&gt;
&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;property&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;string&quot;&gt;&amp;quot;color&amp;quot;&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;,&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;color_map&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)&lt;/span&gt;
&lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;property&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;string&quot;&gt;&amp;quot;pos&amp;quot;&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;,&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;position_map&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)&lt;/span&gt;
&lt;/pre&gt;
&lt;/li&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=&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;make_iterator_property_map&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;
&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;pointer&lt;/span&gt; &lt;span class=&quot;keyword&quot;&gt;or&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;container&lt;/span&gt; &lt;span class=&quot;special&quot;&gt;.&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;begin&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;()&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;span class=&quot;identifier&quot;&gt;get&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;vertex_index&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;,&lt;/span&gt; &lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;graph&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;object&lt;/span&gt;&lt;span class=&quot;special&quot;&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=&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;make_iterator_property_map&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;
&lt;span class=&quot;special&quot;&gt;&amp;lt;&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;pointer&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;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;typed_identity_property_map&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&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;special&quot;&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=&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;property_map&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;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; that can be un-commented to find
deprecated uses of pointers in user code.
&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/rational&quot;&gt;Rational&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;lowest&lt;/span&gt;&lt;/code&gt; and
&lt;code&gt;&lt;span class=&quot;identifier&quot;&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.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Changed initialization of some internal variables to something that
cannot be a narrowing conversion, which fixes issue &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5855&quot;&gt;#5855&lt;/a&gt;. Needed
since narrowing conversions are an error in C++11.
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Added &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_ptr&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; header, extracted from Boost.Log.
The header implements a mixin base class that adds support for &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;intrusive_ptr&lt;/span&gt;&lt;/code&gt; to user's classes.
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div&gt;
&lt;em&gt;New Features:&lt;/em&gt;
&lt;ul&gt;

&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/8519&quot;&gt;#8519&lt;/a&gt;

&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/8615&quot;&gt;#8615&lt;/a&gt;

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

&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/8677&quot;&gt;#8677&lt;/a&gt;
Async: Add future&amp;lt;&amp;gt;::get_or.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/8678&quot;&gt;#8678&lt;/a&gt;
Async: Add future&amp;lt;&amp;gt;::fallback_to.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/8891&quot;&gt;#8891&lt;/a&gt;
upgrade_to_unique_lock: missing mutex() function.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/8955&quot;&gt;#8955&lt;/a&gt;
Request for more efficient way to get exception_ptr from future.
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&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;a href=&quot;http://svn.boost.org/trac/boost/ticket/7461&quot;&gt;#7461&lt;/a&gt;

&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/8768&quot;&gt;#8768&lt;/a&gt;
win32 condition_variable::wait_until infinite wait in rare
cases.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/8817&quot;&gt;#8817&lt;/a&gt;
Boost Thread Windows CE _createthreadex handling breaks mingw

&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/8943&quot;&gt;#8943&lt;/a&gt;

Composer XE 2013 on Windows.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/8931&quot;&gt;#8931&lt;/a&gt;
Typos in external_locking reference.

&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/9029&quot;&gt;#9029&lt;/a&gt;
Misprint in documentation.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/9037&quot;&gt;#9037&lt;/a&gt;
gcc -Wshadow gives warnings in condition_variable{,_fwd}.hpp.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/9041&quot;&gt;#9041&lt;/a&gt;
Boost.Thread DSO's may need to link with Boost.Atomic.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/9048&quot;&gt;#9048&lt;/a&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=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/timer/&quot;&gt;Timer&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Fixed compilation on Intel compiler &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8956&quot;&gt;#8956&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/type_traits/&quot;&gt;Type Traits&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;is_copy_contructible&lt;/span&gt;&lt;/code&gt;
trait &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8802&quot;&gt;#8802&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/unordered/&quot;&gt;Unordered&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Avoid some warnings (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8851&quot;&gt;#8851&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8874&quot;&gt;#8874&lt;/a&gt;).
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Avoid exposing some detail functions via. ADL on the iterators.
&lt;/div&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;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/utility/index.html&quot;&gt;Utility&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&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;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=&quot;keyword&quot;&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=&quot;identifier&quot;&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=&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;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=&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;utility&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;explicit_operator_bool&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; 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;utility&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;/&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;empty_deleter&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;
headers, which were extracted from Boost.Log. The headers implement
utilities for defining explicit conversion operators to &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;bool&lt;/span&gt;&lt;/code&gt; and a deleter function object
that does nothing, respectively.
&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/variant/&quot;&gt;Variant&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&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;pentium4m&lt;/tt&gt;, &lt;tt&gt;prescott&lt;/tt&gt;, &lt;tt&gt;nocona&lt;/tt&gt;,
&lt;tt&gt;core2&lt;/tt&gt;, &lt;tt&gt;corei7&lt;/tt&gt;, &lt;tt&gt;corei7-avx&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;conroe-l&lt;/tt&gt;, &lt;tt&gt;allendale&lt;/tt&gt;, &lt;tt&gt;merom&lt;/tt&gt;,
&lt;tt&gt;merom-xe&lt;/tt&gt;, &lt;tt&gt;kentsfield&lt;/tt&gt;, &lt;tt&gt;kentsfield-xe&lt;/tt&gt;,
&lt;tt&gt;penryn&lt;/tt&gt;, &lt;tt&gt;wolfdale&lt;/tt&gt;, &lt;tt&gt;yorksfield&lt;/tt&gt;,
&lt;tt&gt;nehalem&lt;/tt&gt;, &lt;tt&gt;sandy-bridge&lt;/tt&gt;, &lt;tt&gt;ivy-bridge&lt;/tt&gt;,
&lt;tt&gt;haswell&lt;/tt&gt;, &lt;tt&gt;atom&lt;/tt&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
AMD CPUs: &lt;tt&gt;k6&lt;/tt&gt;, &lt;tt&gt;k6-2&lt;/tt&gt;, &lt;tt&gt;k6-3&lt;/tt&gt;,
&lt;tt&gt;athlon&lt;/tt&gt;, &lt;tt&gt;athlon-tbird&lt;/tt&gt;, &lt;tt&gt;athlon-4&lt;/tt&gt;,
&lt;tt&gt;athlon-xp&lt;/tt&gt;, &lt;tt&gt;athlon-mp&lt;/tt&gt;, &lt;tt&gt;k8&lt;/tt&gt;,
&lt;tt&gt;opteron&lt;/tt&gt;, &lt;tt&gt;athlon64&lt;/tt&gt;, &lt;tt&gt;athlon-fx&lt;/tt&gt;,
&lt;tt&gt;k8-sse3&lt;/tt&gt;, &lt;tt&gt;opteron-sse3&lt;/tt&gt;, &lt;tt&gt;athlon64-sse3&lt;/tt&gt;,
&lt;tt&gt;amdfam10&lt;/tt&gt;, &lt;tt&gt;barcelona&lt;/tt&gt;, &lt;tt&gt;bdver1&lt;/tt&gt;,
&lt;tt&gt;bdver2&lt;/tt&gt;, &lt;tt&gt;bdver3&lt;/tt&gt;, &lt;tt&gt;btver1&lt;/tt&gt;,
&lt;tt&gt;btver2&lt;/tt&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
VIA CPUs: &lt;tt&gt;c3&lt;/tt&gt;, &lt;tt&gt;c3-2&lt;/tt&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
IDT CPUs: &lt;tt&gt;winchip-c6&lt;/tt&gt;, &lt;tt&gt;winchip2&lt;/tt&gt;
&lt;/div&gt;

Note that not all these values may be supported by a particular compiler.
&lt;/p&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;div&gt;
&lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/tti/&quot;&gt;TTI&lt;/a&gt;:&lt;/span&gt;
Type Traits Introspection library,

&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/type_erasure/&quot;&gt;Type Erasure&lt;/a&gt;:&lt;/span&gt;

&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;
&lt;div id=&quot;version_1_54_0.updated_libraries&quot;&gt;
&lt;h3&gt;&lt;span class=&quot;link&quot;&gt;Updated Libraries&lt;/span&gt;&lt;/h3&gt;

&lt;li&gt;
&lt;div&gt;
&lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/accumulators/&quot;&gt;Accumulators&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Fixes comment typos (&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/7917&quot;&gt;#7917&lt;/a&gt;)
&lt;/div&gt;
&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;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;
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;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;div&gt;

&lt;li&gt;
&lt;div&gt;
Fixed warnings (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8032&quot;&gt;#8032&lt;/a&gt;).

&lt;li&gt;
&lt;div&gt;
Added experimental &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;static_vector&lt;/span&gt;&lt;/code&gt;
class, based on Andrew Hundt's and Adam Wulkiewicz's high-performance
&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;varray&lt;/span&gt;&lt;/code&gt; class.
&lt;/div&gt;
&lt;/li&gt;

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

&lt;div&gt;
&lt;em&gt;Additional functionality&lt;/em&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
added Spatial Index, developed for Boost.Geometry by Adam Wulkiewicz.
The spatial index was originally started by Federico J. Fernandez
during the Google Summer of Code 2008 program, mentored by
Hartmut Kaiser.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
added SVG-output, this was already in extensions for several
years
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;

&lt;li&gt;
&lt;div&gt;
&lt;em&gt;Bugfixes&lt;/em&gt;

a robustness issue, fixed
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;

fixed insertion of false intersection point (found by buffer)
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
applied patch of Vladimir Petrovic for debugging traversals
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;

&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8393&quot;&gt;8393&lt;/a&gt;
polygon model doesn't adhere to stated Polygon concept rules,
doc updated.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8403&quot;&gt;8403&lt;/a&gt;

&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;em&gt;Internal changes&lt;/em&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Made several algorithms variant-aware (append, area, clear,
convert, equals, length, num_points)
&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;
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;/ul&gt;
&lt;/div&gt;

&lt;ul&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;div&gt;
Fixed bugs &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7484&quot;&gt;#7484&lt;/a&gt;,
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7598&quot;&gt;#7598&lt;/a&gt;,

&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8595&quot;&gt;#8595&lt;/a&gt;.
&lt;/div&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;/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/intrusive/&quot;&gt;Intrusive&lt;/a&gt;:&lt;/span&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;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/iostreams/&quot;&gt;Iostreams&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&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;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Documentation fixes (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8385&quot;&gt;#8385&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8460&quot;&gt;#8460&lt;/a&gt;).
&lt;/div&gt;
&lt;/li&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;/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/conversion/lexical_cast.htm&quot;&gt;Lexical cast&lt;/a&gt;:&lt;/span&gt;
&lt;ul&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;/div&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;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;a href=&quot;https://svn.boost.org/trac/boost/ticket/8369&quot;&gt;#8369&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8547&quot;&gt;#8547&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;/ul&gt;

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

&lt;div&gt;
Fixed bugs &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7969&quot;&gt;#7969&lt;/a&gt;),
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8231&quot;&gt;#8231&lt;/a&gt;).

&lt;div&gt;
&lt;strong&gt;Breaking change&lt;/strong&gt; renamed &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;rational_adapter&lt;/span&gt;&lt;/code&gt; to &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;rational_adaptor&lt;/span&gt;&lt;/code&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Add support for &lt;a href=&quot;http://perso.ens-lyon.fr/nathalie.revol/software.html&quot;&gt;MPFI&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Add logged_adaptor.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Add support for 128-bit floats via GCC's &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;__float128&lt;/span&gt;&lt;/code&gt;
or Intel's &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;_Quad&lt;/span&gt;&lt;/code&gt;
data types.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Add support for user-defined literals in cpp_int, improve &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;constexpr&lt;/span&gt;&lt;/code&gt; support.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed bug in integer division of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;cpp_int&lt;/span&gt;&lt;/code&gt;
that results in incorrect sign of &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;cpp_int&lt;/span&gt;&lt;/code&gt;
when both arguments are small enough to fit in a &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;double_limb_type&lt;/span&gt;&lt;/code&gt;.
See &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8126&quot;&gt;8126&lt;/a&gt;.

&lt;div&gt;
Fixed bug in subtraction of a single limb in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;cpp_int&lt;/span&gt;&lt;/code&gt;
that results in incorrect value when the result should have a 0 in
the last limb: &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8133&quot;&gt;8133&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed bug in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;cpp_int&lt;/span&gt;&lt;/code&gt;
where division of 0 by something doesn't get zero in the result:
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/8160&quot;&gt;8160&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed bug in some transcendental functions that caused incorrect
return values when variables are reused, for example with &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;a&lt;/span&gt; &lt;span class=&quot;special&quot;&gt;=&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;pow&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;a&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;,&lt;/span&gt; &lt;span class=&quot;identifier&quot;&gt;b&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)&lt;/span&gt;&lt;/code&gt;.

&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Updated the Knuth-Morris-Pratt docs (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7656&quot;&gt;#7656&lt;/a&gt;).
&lt;/div&gt;
&lt;/li&gt;

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

&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Fixed some 64-to-32-bit conversion warnings (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7459&quot;&gt;#7459&lt;/a&gt;).
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed some small errors in documentation and comments (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7761&quot;&gt;#7761&lt;/a&gt;).
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed an error in the example embedded in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;basic_socket&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;::&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;get_option&lt;/span&gt;&lt;/code&gt;'s

&lt;div&gt;

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

&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Refactor map_view_iterator to improve error messages.
&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;
&lt;div&gt;
Fixed vector_of and list_of views &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;assign&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;size_type&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;,&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;value_type&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)&lt;/span&gt;&lt;/code&gt; bug.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed vector_of views &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;span class=&quot;identifier&quot;&gt;size_type&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;at&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;identifier&quot;&gt;size_type&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;)&lt;/span&gt;&lt;/code&gt; functions return value.
&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;em&gt;Deprecated:&lt;/em&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&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;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
chrono I/O: The manipulators __duration_short, __duration_long
are depreceated. You should use the parameterized form __duration_fmt
or the renamed manipulators __duration_symbol and __duration_prefix
instead.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
chrono I/O: The __duration_punct&amp;lt;&amp;gt; facet is depreceated.
You should use the __get_duration_style free function to get
the informations and use the __duration_units facet for localization
purposes.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
When BOOST_CHRONO_VERSION==2 the preceding deprecated functions
are not available.
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;em&gt;Fixes:&lt;/em&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7546&quot;&gt;#7546&lt;/a&gt;
time_point&amp;lt;system_clock&amp;gt; output version 2 fails to compile
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7547&quot;&gt;#7547&lt;/a&gt;
time_point&amp;lt;system_clock&amp;gt; input version 2 fails to compile
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7868&quot;&gt;#7868&lt;/a&gt;
chrono_io parses time incorrectly (1.53 and 1.52)
&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/container/&quot;&gt;Container&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Fixed bug &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7650&quot;&gt;#7650&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Improved &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;vector&lt;/span&gt;&lt;/code&gt;'s
insertion performance.
&lt;/div&gt;
&lt;/li&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;li&gt;
&lt;div&gt;
Fixed GCC -Wshadow warnings.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Replaced deprecated BOOST_NO_XXXX with newer BOOST_NO_CXX11_XXX 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/context/&quot;&gt;Context&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;

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

&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
&lt;em&gt;New Features:&lt;/em&gt;
&lt;ul&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;/div&gt;
&lt;/li&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Fixed a bug where it wouldn't find overlapping patterns (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7784&quot;&gt;#7784&lt;/a&gt;).
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Disambiguated some calls to insert (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7346&quot;&gt;#7346&lt;/a&gt;).
&lt;/div&gt;
&lt;/li&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

&lt;div id=&quot;version_1_52_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;http://www.boost.org/libs/accumulators/&quot;&gt;Accumulators&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Fix long-standing dependency tracking bug, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7409&quot;&gt;#7409&lt;/a&gt;
&lt;/div&gt;
&lt;/li&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Define &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_NO_SFINAE_EXPR&lt;/span&gt;&lt;/code&gt;
for gcc-4.4, since the support was found to be too buggy.
&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;em&gt;New Features:&lt;/em&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5980&quot;&gt;#5980&lt;/a&gt; Enhance chrono I/O with H. Hinnant proposal &lt;a href=&quot;http://home.roadrunner.com/~hinnant/bloomington/chrono_io.html&quot;&gt;proposal&lt;/a&gt;
which has the advantage to provide I/O for system clocks using
the Gregorian Calendar.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/5981&quot;&gt;#5981&lt;/a&gt; Add i/o state savers for duration and time_point formatting
state.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7059&quot;&gt;#7059&lt;/a&gt; Add low level i/o facilities.
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;em&gt;Deprecated features:&lt;/em&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&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;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
chrono I/O: The manipulators &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;__duration_short&lt;/span&gt;&lt;/code&gt;,
&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;__duration_long&lt;/span&gt;&lt;/code&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.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
chrono I/O: The &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;__duration_punct&lt;/span&gt;&lt;span class=&quot;special&quot;&gt;&amp;lt;&amp;gt;&lt;/span&gt;&lt;/code&gt; facet is deprecated.
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
localization purposes.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
When &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_CHRONO_VERSION&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;/code&gt;
the preceding deprecated functions are not available.
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;em&gt;Fixes:&lt;/em&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7381&quot;&gt;#7381&lt;/a&gt; C++11 compliance: unresolved symbol when assigning
a constexpr duration to a non-const local variable.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;http://svn.boost.org/trac/boost/ticket/7479&quot;&gt;#7479&lt;/a&gt;
Compile fails with compilers supporting constexpr fails if
the standard library doesn't provides the constexpr interface
&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;em&gt;Would not fix:&lt;/em&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6871&quot;&gt;#6871&lt;/a&gt; chrono_io.hpp: &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;os&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;
modifies the state of os. The neww io interface provided in
version 2 solves this issue. You should move to the new version.
&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/container/&quot;&gt;Container&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Improved &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;stable_vector&lt;/span&gt;&lt;/code&gt;'s
template code bloat and type safety.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Changed typedefs and reordered functions of sequence containers to
improve doxygen documentation.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fixed bugs &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6615&quot;&gt;#6615&lt;/a&gt;,
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7139&quot;&gt;#7139&lt;/a&gt;,

&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7439&quot;&gt;#7439&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Implemented LWG Issue #149 (range insertion now returns an iterator)
&amp;amp; cleaned up insertion code in most containers
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Corrected aliasing errors.
&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/date_time/&quot;&gt;DateTime&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Document &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;BOOST_DATE_TIME_NO_LIB&lt;/span&gt;&lt;/code&gt;
(&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6077&quot;&gt;#6077&lt;/a&gt;).
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fix &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;nth_as_str&lt;/span&gt;&lt;/code&gt; (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7022&quot;&gt;#7022&lt;/a&gt;).
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
Fix some warnings (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7234&quot;&gt;#7234&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/foreach/&quot;&gt;Foreach&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Fix alignment warning on gcc.
&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/function/&quot;&gt;Function&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Move constructors and move assignment operators added (only for compilers
with C++11 rvalue references support) &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7330&quot;&gt;#7330&lt;/a&gt;.
&lt;/div&gt;
&lt;/li&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Fixed bugs &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/6950&quot;&gt;#6950&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7226&quot;&gt;#7226&lt;/a&gt;,&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7308&quot;&gt;#7308&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7327&quot;&gt;#7327&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7338&quot;&gt;#7338&lt;/a&gt;,
&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7341&quot;&gt;#7341&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7378&quot;&gt;#7378&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7380&quot;&gt;#7380&lt;/a&gt;, &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7398&quot;&gt;#7398&lt;/a&gt;, and &lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7428&quot;&gt;#7428&lt;/a&gt;, plus others
not in Trac.
&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/functional/hash/&quot;&gt;Hash&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Restore &lt;code&gt;&lt;span class=&quot;keyword&quot;&gt;enum&lt;/span&gt;&lt;/code&gt; support,
which was accidentally removed in the last version (&lt;a href=&quot;https://svn.boost.org/trac/boost/ticket/7437&quot;&gt;#7437&lt;/a&gt;).
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
New floating point hasher - will hash the binary representation on
more platforms, which should be faster.
&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/interprocess/&quot;&gt;Interprocess&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Added &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;shrink_by&lt;/span&gt;&lt;/code&gt; and
&lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;advise&lt;/span&gt;&lt;/code&gt; functions
in &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;mapped_region&lt;/span&gt;&lt;/code&gt;.
&lt;/div&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;div&gt;
&lt;em&gt;ABI breaking:&lt;/em&gt; Reimplemented &lt;code&gt;&lt;span class=&quot;identifier&quot;&gt;message_queue&lt;/span&gt;&lt;/code&gt; with a circular buffer
index (the old behavior used an ordered array, leading to excessive
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;li&gt;
&lt;div&gt;
&lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/iterator/&quot;&gt;Iterator&lt;/a&gt;:&lt;/span&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Fixed:
&lt;ul&gt;
&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;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;
&lt;span class=&quot;library&quot;&gt;&lt;a href=&quot;http://www.boost.org/libs/conversion/lexical_cast.htm&quot;&gt;Lexical cast&lt;/a&gt;:&lt;/span&gt;
&lt;ul&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;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;

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;/div&gt;
&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
expression.
&lt;/div&gt;

&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.
&lt;ul&gt;
&lt;li&gt;
&lt;div&gt;
Time related functions don't using the Boost.Chrono library,
use the chrono overloads instead.

(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.
