Version 1.46.0

February 21st, 2011 20:36 GMT

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.

Updated Tools

  • Boostbook:
      - 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.
