          + Fixed bugs #2785, #3285.
     * Foreach:
          + Workaround for conflict with Python headers (#3000).

          + Various minor fixes (#2642, #2847, #2929 #3012)
     * Fusion:
          + Improved compile times for fusion::vector.
     * 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.
     * Intrusive:
          + Code cleanup in tree_algorithms.hpp and avl_tree_algorithms.hpp
          + Fixed bug #3164.
     * MPL:
          + Added mpl::char_ and mpl::string for compile-time string manipulation, based on multichar literals (#2905).

     * Program.Options:
          + Support for building with disabled exceptions (#2096).
          + Unicode parser no longer drops original tokens (#2425).
          + Fixed crash on user-inserted items in variables_map (#2782).
     * Proto:
          + PrimitiveTransforms have stricter conformance to ResultOf protocol. (Warning: some invalid code may break.)
          + Add a sensible default for proto::_default's template parameter.
          + Improved default evaluation strategy for pointers to members.
          + GCC 3.4 portability fixes (#3021).

     * 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).
     * Unordered:
          + Implement emplace for all compilers, not just ones with rvalue references and variadic templates (#1978).
          + Create less buckets by default.
          + Some minor tweaks for better compiler support (#2908, #3096, #3082).
     * Xpressive:
          + Works on Visual C++ 10.0 (#3124).

Build System

   The default naming of libraries in Unix-like environment now matches system conventions, and does not include various decorations. Naming of libraries on Cygwin was also fixed. Support for beta versions of Microsoft Visual Studio 10 was added. With gcc, 64-bit compilation no longer requires that target architecture be specified.

Updated Tools

     * Boostbook:
          + Hide INTERNAL ONLY enums in doxygen documentation (#3242).
          + Tweaked appearance of member classes/structs/unions in a class synopsis.
     * Quickbook:
          + Support python code snippets (#3029).
          + Add teletype source mode (#1202)
