New Libraries

• Icl: Interval Container Library, interval sets and maps and aggregation of associated values, from Joachim Faulhaber.

Updated Libraries

• Array:

  • Added support for cbegin/cend (#4761)
  • Fixed a problem with the Sun compiler (#4757)
• Asio:

  • Fixed an integer overflow problem that occurs when ip::address_v4::broadcast() is used on 64-bit platforms.
  • Fixed a problem on older Linux kernels (where epoll is used without timerfd support) that prevents timely delivery of deadline_timer handlers, after the program has been running for some time (#5045).
• Bind:

  • make_adaptable now documented (#4532)
• Concept Check:

  • fixed warnings with self-assignment (#4918)
• Filesystem:

  • Version 3 of the library is now the default.
  • IBM vacpp: Workaround for compiler bug affecting iterator_facade. (#4912)
  • Verify, clarify, document that <boost/config/user.hpp> can be used to specify BOOST_FILESYSTEM_VERSION. (#4891)
  • Replaced C-style assert with BOOST_ASSERT.
  • Undeprecated unique_path(). Instead, add a note mentioning the workaround for lack of thread safety and possible change to cwd. unique_path() is just too convenient to deprecate!
  • Cleared several GCC warnings.
  • Changed V2 code to use BOOST_THROW_EXCEPTION.
  • Windows: Fix status() to report non-symlink reparse point correctly.
  • Add symlink_option to recursive_directory_iterator, allowing control over recursion into directory symlinks. Note that the default is changed to not recurse into directory symlinks.
  • Reference documentation cleanup, including fixing missing and broken links, and adding missing functions.
  • Miscellaneous implementation code cleanup.
• Fusion:

  • vector copy constructor now copies sequence members in the same order on different platforms (#2823)
• Graph:

  • Fixed Graphviz output to work on Visual C++ 7.1.
  • Replaced assert with BOOST_ASSERT.
  • Changed to Boost.Filesystem v3.
  • Fixed the following bugs from Trac: #1021, #4556, #4631, #4642, #4715, #4731, #4737, #4753, #4758, #4793, #4843, #4851, #4852, #4887, #4914, #4966.
  • Fixed various bugs not in Trac.
• Hash:

  • Support for std::type_index (#4756).
  • Avoid -Wconversion warnings.
• Iostreams:

  • Use BOOST_ASSERT instead of assert.
  • Fixed flush regression (#4590).
• Iterator:

  • fixed problem with implicit_cast (#3645)
• Math:

  • Added Wald, Inverse Gaussian and geometric distributions.
  • Added information about configuration macros.
  • Added support for mpreal as a real-numered type.
• Meta State Machine:

  • Compile-time state machine analysis.
  • Boost.Parameter interface definition for msm::back::state_machine<> template arguments.
  • Possibility to provide a container for the event and deferred event queues. A policy implementation based on a more efficient Boost.CircularBuffer is provided.
  • msm::back::state_machine<>::is_flag_active method made const.
  • Added possibility to enqueue events for delayed processing.
  • Bugfixes

    • #4926.
    • stack overflow using the Defer functor
    • anonymous transition of a submachine not called for the initial state
• Optional:

  • Updated test results with information about expected failures (#2294)
• Pool:

  • Now can set a max_size for pool (#2696)
  • boost/pool/pool.hpp uses reinterpret_cast instead of static_cast (#2941)
  • boost::pool_allocator now works with vector of vectors (#386)
  • Boost pool is now compatible with Microsoft memory leak detection (#4346)
• Program Options:

  • Fixed errors in examples in docs (#3992, #4858)
  • Now takes argv as const (#3909)
• Proto:

  • Breaking change: boost/proto/core.hpp no longer defines functional::pop_front and functional::reverse, which have moved to their own headers under boost/proto/functional
  • Add callable wrappers for more Fusion algorithms (including fusion::at); and callable wrappers for some std utilities like make_pair, first and second, all under the new boost/proto/functional directory
  • Allow transforms to be specified separately from a grammar
  • proto::matches preserves domain-specific expression wrappers
  • Fix ADL issue with operator, in proto::and_ transform
  • Fix handling of grammar checking in expressions involving multiple domains (#4675)
  • Fix ambiguous operator<< in proto::display_expr (#4910)
  • fusion::is_sequence answers true for Proto expressions (#5006)
  • Eliminate -Wundef GCC warning in boost/proto/fusion.hpp (#5075)
• Signals:

  • gcc warning cleanup (#4365)
• Spirit:

  • Spirit V2.4.2, see the 'What's New' section for details.
• Tokenizer:

  • isspace/ispunct was called with wrong character type (#4791)
• Unordered:

  • Avoid using operator& with the value type.
  • Avoid -Wconversion warnings.
• Wave:

  • See the Changelog for details.

  • Better support for attributes on root elements - including lang.
• Inspect:

  • Check that Boost headers do not use C's assert macro.
• Quickbook:

  • Add support for lang attribute in documentation info.
  • Improved anchors.
  • Support import, include and xinclude in conditional phrases.
  • Uses Filesystem 3.
