Version 1.42.0

Tue 2 Feb 2010 14:00:00 GMT

New Libraries

Uuid: A universally unique identifier, from Andy Tompkins.

Updated Libraries

Asio:
- Added a new HTTP Server 4 example illustrating the use of stackless coroutines with Asio.
- Changed handler allocation and invocation to use boost::addressof to get the address of handler objects, rather than applying operator& directly (#2977).
- Restricted MSVC buffer debugging workaround to 2008, as it causes a crash with 2010 beta 2 (#3796, #3822).
- Fixed a problem with the lifetime of handler memory, where Windows needs the OVERLAPPED structure to be valid until both the initiating function call has returned and the completion packet has been delivered.
- Don't block signals while performing system calls, but instead restart the calls if they are interrupted.
- Documented the guarantee made by strand objects with respect to order of handler invocation.
- Changed strands to use a pool of implementations, to make copying of strands cheaper.
- Ensured that kqueue support is enabled for BSD platforms (#3626).
- Added a boost_ prefix to the extern "C" thread entry point function (#3809).
- In getaddrinfo emulation, only check the socket type (SOCK_STREAM or SOCK_DGRAM) if a service name has been specified. This should allow the emulation to work with raw sockets.
- Added a workaround for some broken Windows firewalls that make a socket appear bound to 0.0.0.0 when it is in fact bound to 127.0.0.1.
- Applied a fix for reported excessive CPU usage under Solaris (#3670).
- Added some support for platforms that use older compilers such as g++ 2.95 (#3743).
Circular Buffer:
- Added methods erase_begin(size_type) and erase_end(size_type) with constant complexity for such types of stored elements which do not need an explicit destruction e.g. int or double.
- Similarly changed implementation of the clear() method and the destructor so their complexity is now constant for such types of stored elements which do not require an explicit destruction (the complexity for other types remains linear).
Fusion:
- The accumulator is the first argument to the functor of fusion::fold and fusion::accumulate (#2355).
- Added support for associative iterators and views (#3473).
Graph:
- Removed old interface to compressed_sparse_row_graph, making new interface the default.
Integer:
- Reverted Trunk to release branch state (i.e. a "known good state").
- Fixed issues: 653, 3084, 3177, 3180, 3568, 3657, 2134.
- Added long long support to boost::static_log2, boost::static_signed_min, boost::static_signed_max, boost::static_unsigned_minboost::static_unsigned_max, when available.
- The argument type and the result type of boost::static_signed_min etc are now typedef'd. Formerly, they were hardcoded as unsigned long and int respectively. Please, use the provided typedefs in new code (and update old code as soon as possible).
Iostreams:
- Fixed many outstanding issues. Thanks to Richard Smith for his work on this. (#3612, #3311, #2094, #3010, #2894, #3011, #3352, #3505).
- For more information see the library release notes.
Program.Options:
- Information about option name added to a few exception classes and various clean ups in exception classes (#3423).
- Description wordwrapping in presense of default parameters fixed (#2613).
- Empty value in configuration file is now permitted (#1537).
- Quotes are no longer stripped from string values (#850).
- Fix endless loop in case of long default arguments (#689).
- Fix compile warning caused by usage of boost::any (#2562).
- Fix memory bug in example/response_file.cpp (#3525).
- Most compilation warnings were fixed (#3608).
- Make column width for description text configurable. (#3703).
- Add general split function: split_unix() (#2561).
- Enable open config files from given file name (#3264).
- Additional flag for required options (#2982).
- Enable case insensitive style for command line (#3498).
PropertyMap:
- Removed old header files (directly in the boost/ directory); they were deprecated since 1.40, replaced by headers in boost/property_map/.
Proto:
- Fix const correctness issues with proto::flatten and friends (#3364).
- Accomodate recent change to fusion::fold, remove old support for Doxygen and pre-1.35 Fusion (#3553).
- In binary operations, when one operand has a user-specified domain and the other has the default domain, the user-specified domain trumps.
- Fix BOOST_PROTO_EXTENDS to work with elaborated types.
- Work around EDG compiler bug with function types and cv-qualification.
Regex:
- Added support for Functors rather than strings as format expressions.
- Improved error reporting when throwing exceptions to include better more relevant information.
- Improved performance and reduced stack usage of recursive expressions.
- Fixed tickets #2802, #3425, #3507, #3546, #3631, #3632, #3715, #3718, #3763, #3764
Spirit: Spirit V2.2, see the 'What's New' section for details.
Unordered:
- Support instantiating the containers with incomplete value types.
- Add erase_return_void as a temporary workaround for the current erase which can be inefficient because it has to find the next element to return an iterator (#3693).
- Add templated find overload for compatible keys.
- Improved codegear compatibility.
- Other minor changes, full details in the changelog.
Xpressive:
- match_results no longer relies on undefined behavior in std::list (#3278).

- Gregorian dates now use 32-bit integer type internally on 64-bit platforms (#3308).
- See the full changelog for more detail.
Filesystem:
- Bug fixes: (#3385). (#3528). (#3509).
Iostreams: Some old unreleased developments. There are still several open issues that should be fixed in the next version.

Regex: Added support for many Perl 5.10 syntax elements including named sub-expressions, branch resets and recursive regular expressions.
Spirit: This is the initial official release of the new Spirit V2.1, a completely new library for parsing, lexing, and output generation. Note: this release is not backwards compatible with earlier versions. Known issue: qi::symbol::find will match a symbol that starts with the string you're searching for. This will be fixed in the next version.
System:

Version 1.40.0

Thu, 27 Aug 2009 17:00:00 GMT

Update

Added missing notes for Graph and Property Map.

Fusion:
- Improved compile times for fusion::vector.
Graph:
- Merged in the Parallel Boost Graph Library, giving a full suite of graph algorithms and data structures for distributed-memory computers (such as clusters).
- Updates to the interface of the compressed sparse row graph, including constructors from unsorted edge lists.
- An implicit grid graph, saving memory over using the former generator.
- New algorithms: Dijkstra's single-source shortest path algorithm without a separate color map and an algorithm to find maximal common subgraphs between two graphs.
- Assorted bug fixes.
Hash:
- Automatically configure the float functions using template metaprogramming instead of trying to configure every possibility manually.
Interprocess:
- Windows shared memory is created in Shared Documents folder so that it can be shared between services and processes
- Fixed bugs #2967, #2973, #2992, #3138, #3166, #3205.

- Improved default evaluation strategy for pointers to members.
- GCC 3.4 portability fixes (#3021).
- Work around Visual C++'s non-std-compliant ciso646 macros.
Random:
- Made the constructors of all the generators call the copy constructor when passed a non-const reference.
- Changed seeding functions to accept any arithmetic type. As a side-effect, the exact signature of seed changed for some classes.
- Major bug fixes in uniform_int.
Serialization:
- Removed deprecated headers: boost/static_warning.hpp, boost/state_saver.hpp, boost/smart_cast.hpp, boost/pfto.hpp. Use the the equivalent headers in the boost/serialization/ directory instead (#3062).
- detail::archive_serializer_map should now be used instead of detail::archive_pointer_iserializer. For more details see the library release notes.

Version 1.39.0

Sat, 02 May 2009 12:00:00 GMT

New Libraries

Signals2: Managed signals & slots callback implementation (thread-safe version 2), from Frank Mori Hess.

Updated Libraries

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

Foreach:
- Eliminate shadow warnings on gcc for nested FOREACH loops
- Portability fix for Intel-Win toolset
Hash:
- Remove deprecated headers for hashing containers. Everything that was in them is included in <functional/hash.hpp> (#2412).

Interprocess:
- Increased portability and bug fixes. Full details in the library change log.
Intrusive:
- Optimizations and bug fixes. Full details in the library change log.

Range:
- Bug fixes from Trac applied.
Unordered:
- Fixed regression in 1.38 that prevented unordered from using more than about 1.5 million buckets (#2975).

- Fill in some missing reference documentation (partially fixes #2153).
- Changes to doxygen integration:
  - Support \throw.
  - Support global variables and enums.
  - Better support for documentation written in function and method bodies.
  - Workaround a problem with doxygen 1.5.8's xml output (#2937).

  - Fix a bug for hex encoded characters in strings (#2860).
- Improved testing, including tests for expected failures.
- Generate valid document info for document types other than library (#2711):
  - Remove library specific attributes.
  - Put title before info block.
- Fix a bug when calling templates.

New Libraries

Proto:
- Expression template library and compiler construction toolkit for domain-specific embedded languages, from Eric Niebler.

Updated Libraries

Asio:

- On recent versions of Linux, an eventfd descriptor is now used (rather than a pipe) to interrupt a blocked select/epoll reactor.
- Added const overloads of lowest_layer().
- Synchronous read, write, accept and connect operations are now thread safe (meaning that it is now permitted to perform concurrent synchronous operations on an individual socket, if supported by the OS).
- Reactor-based io_service implementations now use lazy initialisation to reduce the memory usage of an io_service object used only as a message queue.
Circular Buffer:
- Added new methods is_linearized() and rotate(const_iterator).
- Minor bug fixes and documentation updates.
Dynamic Bitset:
- Constructor "do the right thing" dispatch, a la standard sequence containers (follows the proposed resolution of library issue 438, currently in the C++0x working paper).
- Improvements to documentation, code examples and implementation.
Exception:
- Support for non-RTTI builds.
- Optimizations.
- A new macro BOOST_THROW_EXCEPTION which can be used instead of boost::throw_exception when throwing, to automatically record information about the location of the throw in the exception object.
Hash:
- Minor bug fix (ticket 2264).
Interprocess:
- Added placement insertion (emplace(), emplace_back()...) methods to containers.
- Containers can be used now in recursive types.
- Minor bug fixes.
Intrusive:
- Intrusive now takes advantage of compilers with variadic templates.

- Added incremental hashing to unordered containers via incremental<> option.
- Minor bug fixes.
Math.Special Functions: Improved accuracy and testing of the inverse hypergeometric functions.
Type Traits: Added better support for the Codegear compiler.
Unordered:
- Rename overload of emplace with hint, to emplace_hint as specified in n2691.
- Provide forwarding headers at <boost/unordered/unordered_map_fwd.hpp> and <boost/unordered/unordered_set_fwd.hpp>.

Updated Libraries

Graph: Generic graph components and algorithms. Highlights:
- kolmogorov_max_flow, from Stephan Diederich as part of the 2006 Google Summer of Code.
- read_dimacs_max_flow and write_dimacs_max_flow for max-flow problems, from Stephan Diederich.
- read_graphml and write_graphml for GraphML input/output, from Tiago de Paula Peixoto.
- minimum_cycle_ratio and maximum_cycle_ratio, from Dmitry Bufistov and Andrey Parfenov.
- boyer_myrvold_planarity_test, along with a suite of algorithms for planar graphs, from Aaron Windsor.
- LEDA Adaptor improvements, from Jens Müller.
Hash: A TR1 hash function object, from Daniel James. Highlights:
- Support for long long, std::complex.
- Improved the algorithm for hashing floating point numbers.
- A few bug and warning fixes.
Iostreams: Framework for defining streams, stream buffers and i/o filters, from Jonathan Turkanis. Highlights:
- Clarified the semantics of close(). This fixes several bugs but will break some existing code. See Release Notes for details.
- Numerous other bug fixes and optimizations.
Multi Array:
- Added "dimensionality" compile-time constante to the MultiArray concept.
- For greater control over error situations, uses of C++ assert have been replaced with BOOST_ASSERT.
- Fixed a bug with simultaneous resizing and reindexing.
Multi-index Containers:
- New global_fun predefined key extractor.
- Added iterator_to facility.
- Included support for non-standard allocators such as those of Boost.Interprocess, which makes multi_index_containers placeable in shared memory.
- New versions of modify and modify_key with rollback, as described in the tutorial.
- A number of optimizations and minor improvements have also been included. For a complete list of changes, see the library release notes.
Serialization: Boost.Serialization has been updated with optimizations for dense arrays.
Thread:
- The Thread library has been updated to be more in line with the C++0x working draft.
- Instances of boost::thread and of the various lock types are now movable.
- Threads can be interrupted at interruption points.
- Condition variables can now be used with any type that implements the Lockable concept, through the use of boost::condition_variable_any (boost::condition is a typedef to boost::condition_variable_any, provided for backwards compatibility). boost::condition_variable is provided as an optimization, and will only work with boost::unique_lock<boost::mutex> (boost::mutex::scoped_lock).
- Thread IDs are separated from boost::thread, so a thread can obtain it's own ID (using boost::this_thread::get_id()), and IDs can be used as keys in associative containers, as they have the full set of comparison operators.
- Timeouts are now implemented using the Boost DateTime library, through a typedef boost::system_time for absolute timeouts, and with support for relative timeouts in many cases. boost::xtime is supported for backwards compatibility only.
- Locks are implemented as publicly accessible templates boost::lock_guard, boost::unique_lock, boost::shared_lock, and boost::upgrade_lock, which are templated on the type of the mutex. The Lockable concept has been extended to include publicly available lock() and unlock() member functions, which are used by the lock types.
- boost::try_mutex has been removed, and the functionality subsumed into boost::mutex. boost::try_mutex is left as a typedef, but is no longer a separate class.
- boost::recursive_try_mutex has been removed, and the functionality subsumed into boost::recursive_mutex. boost::recursive_try_mutex is left as a typedef, but is no longer a separate class.
- boost::detail::thread::lock_ops has been removed. Code that relies on the lock_ops implementation detail will no longer work, as this has been removed, as it is no longer necessary now that mutex types now have public lock() and unlock() member functions.
- scoped_lock constructors with a second parameter of type bool are no longer provided. With previous boost releases, boost::mutex::scoped_lock some_lock(some_mutex,false); could be used to create a lock object that was associated with a mutex, but did not lock it on construction. This facility has now been replaced with the constructor that takes a boost::defer_lock_type as the second parameter: boost::mutex::scoped_lock some_lock(some_mutex,boost::defer_lock);
- The broken boost::read_write_mutex has been replaced with boost::shared_mutex.
Wave: Standards conformant implementation of the mandated C99/C++ preprocessor functionality packed behind an easy to use iterator interface, from Hartmut Kaiser. Highlights:
- Added the possibility to continue the preprocessing after an error occured.
- Added the macro introspection API to the wave::context object.
- Added threading support to the library.
- Improved the overall performance by upto 30%.
- Changed and unified preprocessor hook interface (this is an interface breaking change!), added several new preprocessor hook functions.
- Added serialization support.
- Added new examples (for instance: Hannibal - a partial C++ parser, by Danny Havenith).
- Added a new lexical analyzer based on Ben Hansons Lexertl library.
- Fixed a large number of other bugs and problems.
Xpressive: Regular expressions that can be written as strings or as expression templates, and that can refer to each other and themselves recursively with the power of context-free grammars, from Eric Niebler. Highlights:
- Added semantic actions to static regexes. A semantic action is code that executes when part of a regular expression matches.
- Added custom assertions to static regexes. A custom assertion is a Boolean predicate that can participate in the regex match.
- Added named regexes for embedding a static or dynamic regex into a dynamic regex. This can be used to create dynamic regex grammars.
- Added named captures to dynamic regexes, like Perl.

This is a bug fix release addressing many problems with the 1.34.0 release. It is a recommended upgrade for all users of Boost 1.34.0. For a complete list of fixes see Boost Trac.

Supported Compilers

New in this release is improved support for the IBM XL C/C++ compiler.

Boost is tested on a wide range of compilers and platforms. Since Boost libraries rely on modern C++ features not available in all compilers, not all Boost libraries will work with every compiler. New in this release The following compilers and platforms have been extensively tested with Boost, although many other compilers and platforms will work as well. For more information, see the regression test results.

Apple GCC 4.0.1 on Mac OS X.
Borland C++ 5.8.2 on Windows.
GNU C++
- 3.2.x., 3.3.x, 3.4.x, 4.0.x, 4.1.x on Linux
- 4.1.x on Solaris
- 3.4.x on Windows
HP C++ for Tru64 UNIX 7.1.

Version 1.34.0

Sat, 12 May 2007 12:00:00 GMT

New Libraries

Foreach Library: BOOST_FOREACH macro for easily iterating over the elements of a sequence, from Eric Niebler.
Statechart Library: Arbitrarily complex finite state machines can be implemented in easily readable and maintainable C++ code, from Andreas Huber.
TR1 Library: An implementation of the C++ Technical Report on Standard Library Extensions, from John Maddock. This library does not itself implement the TR1 components, rather it's a thin wrapper that will include your standard library's TR1 implementation (if it has one), otherwise it will include the Boost Library equivalents, and import them into namespace std::tr1. Highlights include: Reference Wrappers, Smart Pointers, result_of, Function Object Binders, Polymorphic function wrappers, Type Traits, Random Number Generators and Distributions, Tuples, Fixed Size Array, Hash Function Objects, Regular Expressions, and Complex Number Additional Algorithms.
Typeof Library: Typeof operator emulation, from Arkadiy Vertleyb and Peder Holt.
Xpressive Library: Regular expressions that can be written as strings or as expression templates, and that can refer to each other and themselves recursively with the power of context-free grammars, from Eric Niebler.

Assign Library:
- Support for ptr_map<key,T> via the new function ptr_map_insert()
- Support for initialization of Pointer Containers when the containers hold pointers to an abstract base class.
Date_time library:
- Support for new US/Canada timezone rules and other bug fixes. See Change History for details.

- Preservation of existing user code whenever possible.
- More efficient directory iteration.
- Addition of a recursive directory iterator.
Function Library: Boost.Function now implements a small buffer optimization, which can drastically improve the performance when copying or constructing Boost.Function objects storing small function objects. For instance, bind(&X:foo, &x, _1, _2) requires no heap allocation when placed into a Boost.Function object.
Functional/Hash Library:
- Use declarations for standard classes, so that the library doesn't need to include all of their headers
- Deprecated the <boost/functionalhash*.hpp> headers.
- Add support for the BOOST_HASH_NO_EXTENSIONS macro, which disables the extensions to TR1
- Minor improvements to the hash functions for floating point numbers.
Graph Library:

- Note: the name of the compiled library for the GraphViz reader has changed to boost_graph (from bgl-viz) to match Boost conventions.
- See the complete revision history for more information.
MultiArray Library: Boost.MultiArray now by default provides range-checking for operator[]. Range checking can be disabled by defining the macro BOOST_DISABLE_ASSERTS before including multi_array.hpp. A bug in multi_array::resize() related to storage orders was fixed.
Multi-index Containers Library:
- New random access indices.
- Non key-based indices feature new rearrange facilities.
- This version also includes a number of optimizations and usage improvements. For a complete list of changes, see the library release notes.

- boost::none_t and boost::none now added to Optional's documentation
- Relational operators now directly support arguments of type 'T' and 'none_t'
- operator->() now also works with reference types.
- Helper functions make_optional(val), make_optional(cond,val) and get_optional_value_or(opt,alternative_value) added.
- Constructor taking a boolean condition (as well as a value) added.
- Member function get_value_or(alternative_value) added.
- Incompatbility bug with mpl::apply<> fixed.
- Converting assignment bug with uninitialized lvalues fixed.
Parameter Library:
- Every ArgumentPack is now a valid MPL Forward Sequence.
- Support for unnamed arguments (those whose keyword is deduced from their types) is added.
- Support for named and unnamed template arguments is added.
- New overload generation macros solve the forwarding problem directly.
- See also the Python library changes, below.
Pointer Container Library:
- Support for serialization via Boost.Serialization.
- Exceptions can be disabled by defining the macro BOOST_PTR_CONTAINER_NO_EXCEPTIONS before including any header. This macro is defined by default if BOOST_NO_EXCEPTIONS is defined.
- Additional std::auto_ptr<T> overloads added s.t. one can also pass std::auto_ptr<T> instead of only T* arguments to member functions.
- transfer() now has weaker requirements s.t. one can transfer objects from ptr_container<Derived> to ptr_container<Base>,
Python Library:
- Boost.Python now automatically appends C++ signatures to docstrings. The new docstring_options.hpp header is available to control the content of docstrings.
- stl_input_iterator, for turning a Python iterable object into an STL input iterator, from Eric Niebler.
- Support for void* conversions is added.
- Integrated support for wrapping C++ functions built with the parameter library; keyword names are automatically known to docsstrings.
- Enhancements to the API for better embedding support (boost::python::import(), boost::python::exec(), and boost::python::exec_file()).
Signals Library: More improvements to signal invocation performance from Robert Zeh.
Smart Pointers Library:
- Allocator support as proposed in N1851 (162 Kb PDF).
- pointer_cast and pointer_to_other utilities to allow pointer-independent code, from Ion Gaztanaga.
String Algorithm Library:
- lexicographical_compare
- join
- New comparison predicates is_less, is_not_greater.
- Negative indexes support (like Perl) in various algorihtms (*_head/tail, *_nth).
Wave Library:
- Wave now correctly recognizes pp-number tokens as mandated by the C++ Standard, which are converted to C++ tokens right before they are returned from the library.
- Several new preprocessing hooks have been added. For a complete description please refer to the related documentation page: The Context Policy.
- Shared library (dll) support has been added for the generated Wave libraries.
- The overall error handling has been improved. It is now possible to recover and continue after an error or a warning was issued.
- Support for optional comment and/or full whitespace preservation in the generated output stream has been added.
- The Wave library now performs automatic include guard detection to avoid accessing header files more than once, if appropriate.
- Full interactive mode has been added to the Wave tool. Now the Wave tool can be used just like Python or Perl for instance to interactively try out your BOOST_PP macros. Additionally it is now possible to load and save the current state of an interactive session (macro tables et.al.).
- The overall performance has been improved by upto 40-60%, depending on the concrete files to process.
- Support for new pragmas has been added allowing to control certain library features from inside the preprocessed sources (partial output redirection, control of generated whitespace and #line directives).
- Optional support for #pragma message "..." has been added.
- This version also includes a number of bug fixes and usage improvements. For a complete list of changes, see the libraries change log.

Version 1.31.0

Mon, 26 Jan 2004 12:00:00 GMT

New License

A unified Boost Software License has been developed and will gradually replace the individual licenses for most Boost libraries. The new license offers better legal protection for both users and developers, and should speed user's legal reviews of Boost libraries. Dave Abrahams led the Boost effort to develop better licensing. The legal team was led by Diane Cabell, Director, Clinical Programs, Berkman Center for Internet & Society, Harvard Law School. Devin Smith, attorney, Nixon Peabody LLP, wrote the Boost License. Eva Chan, Harvard Law School, contributed analysis of issues and drafts of various legal documents.

Note: Many of the Boost libraries are still using earlier licenses, though all conform to the Boost License Requirements. After this release we will begin an effort to move toward uniform use of the new license.

Mon, 4 Aug 2003 12:00:00 GMT

This release was withdrawn on the 12 Aug 2003.

Fixes were made to the following libraries: * The Boost.Lambda ..library is now usable with gcc-2.95.2 * Boost.Spirit: * Fixed. Using MSVC++6 (SP5), calling the assign action with a string value on parsers using the file_iterator will not work. * Fixed: using assign semantic action in a grammar with a multi_pass iterator adaptor applied to an std::istream_iterator resulted in a failure to compile under msvc 7.0. * Fixed: There is a bug in the range_run<CharT>::set(range<CharT> const& r) function in "../boost/spirit/utility/impl/chset/range_run.ipp". * Fixed: handling of trailing whitespace bug (ast_parse/pt_parse related) * Fixed: comment_p and end of data bug * Fixed: Most trailing space bug * Fixed: chset<>::operator ~(range<>) bug, operator &(chset<>, range<>) bug, operator &(range<>, chset<>) bug * Fixed: impl::detach_clear bug * Fixed: mismatch closure return type bug * Fixed: access_node_d[] and access_match_d[] iterator bugs * Fixed a bug regarding thread safety of Phoenix/Spirit closures. * The Boost Template Metaprogramming Library (MPL)'s ..typeof implementation is now compatible with Metrowerks CodeWarrior Pro8. * Boost.Function: workaround for the new Borland patch (version 0x564) and MSVC++ .NET 2003. * Boost.Config, Boost.Format, and Boost.Regex ..have been adjusted to avoid warnings with GCC-3.3, and Boost.Format also now works with string types other than std::string. * Smart Pointers: * checked_delete now works on more platforms * Compatibility with the SunPro compiler * Added missing #includes. * Boost.Python: * warning suppression for finicky compilers * fixed a crashing bug in the raw_function facility when no keyword arguments were passed. * Improved conversion of NULL shared_ptrs to Python.
