Version 1.38.0
New Libraries
* Flyweight:
+ Design pattern to manage large quantities of highly redundant objects, from Joaquín M López Muñoz.
* ScopeExit:
+ Execute arbitrary code at scope exit, from Alexander Nasonov.
* Swap:
+ Enhanced generic swap function, from Joseph Gauterin.
Updated Libraries
* Any:
+ Use a by-value argument for operator= (#2311).
* Accumulators:
+ Add rolling_sum, rolling_count and rolling_mean accumulators.
* Config:
+ Add new macros BOOST_NO_STD_UNORDERED and BOOST_NO_INITIALIZER_LISTS.
+ Added Codegear compiler support.
+ Added Dragonfly to the BSD family of configs.
+ Updated MSVC's binary ABI settings to match compiler default when doing 64-bit builds.
+ Recognise latest compilers from MS and Intel.
* Date_Time:
+ Added support for formatting and reading time durations longer than 24 hours with new formatter: %0.
+ Removed the testfrmwk.hpp file from the public include directory.
+ Fixed several bugs and compile errors.
+ For full details see the change history
* Exception:
+ Improved and more customizable diagnostic_information output.
* Filesystem:
+ Fix native(name) test failures on POSIX-like systems.
+ Several bugfixes (#2543, #2224, #2531, #1840, #2542).
* Graph:
+ Added a new algorithms for Traveling Salesman Problem approximation (metric_tsp_approx) and resource-constrained Shortest Paths (r_c_shortest_paths).
+ Support for named vertices in adjacency_list.
+ A number of bugfixes ( #416, #1622, #1700, #2209, #2392, #2460, and #2550)
* Hash:
+ boost/functional/detail/container_fwd.hpp has been moved to boost/detail/container_fwd.hpp. The current location is deprecated.
+ For more detail, see the library changelog.
* Interprocess:
+ Updated documentation to show rvalue-references funcions instead of emulation functions.
+ More non-copyable classes are now movable.
+ Move-constructor and assignments now leave moved object in default-constructed state instead of just swapping contents.
+ Several bugfixes (#2391, #2431, #1390, #2570, #2528).
* Intrusive:
+ New treap-based containers: treap, treap_set, treap_multiset.
+ Corrected compilation bug for Windows-based 64 bit compilers.
+ Corrected exception-safety bugs in container constructors.
+ Updated documentation to show rvalue-references funcions instead of emulation functions.
* Lexical Cast:
+ Changed to work without RTTI when BOOST_NO_TYPEID is defined. (#1220).
* Math:
+ Added Johan Råde's optimised floating point classification routines.
+ Fixed code so that it compiles in GCC's -pedantic mode (bug report #1451).
* Multi-index Containers: Some redundant type definitions have been deprecated. Consult the library release notes for further information.
* Proto:
+ Fix problem with SFINAE of binary operators (Bug 2407).
+ Fix proto::call transform for callable transforms with >3 arguments.
+ result_of::value changed behavior for array-by-value terminals.
+ unpack_expr requires only Forward Sequences rather than Random Access Sequences.
+ Deprecate legacy undocumented BOOST_PROTO_DEFINE_(VARARG_)FUNCTION_TEMPLATE macros.
+ Add BOOST_PROTO_REPEAT and BOOST_PROTO_LOCAL_ITERATE macros to help with repetitive code generation
+ Support for nullary expressions with tag types other than proto::tag::terminal
+ Allow 0- and 1-argument variants of proto::or_ and proto::and_
* Regex:
+ Breaking change: empty expressions, and empty alternatives are now allowed when using the Perl regular expression syntax. This change has been added for Perl compatibility, when the new syntax_option_type no_empty_expressions is set then the old behaviour is preserved and empty expressions are prohibited. This is issue #1081.
+ Added support for Perl style ${n} expressions in format strings (issue #2556).
+ Added support for accessing the location of sub-expressions within the regular expression string (issue #2269).
+ Fixed compiler compatibility issues #2244, #2514, and #2458.
* Thread:
+ No longer catches unhandled exceptions in threads as this debuggers couldn't identify the cause of unhandled exceptions in threads. An unhandled exception will still cause the application to terminate.
* TR1:
+ Added support for the TR1 math functions and the unordered containers.
* Type Traits:
+ Added support for Codegear intrinsics.
+ Minor tweaks to warning suppression and alignment_of code.
* Unordered:
+ Use boost::swap.
+ Use a larger prime number list for selecting the number of buckets.
+ Use aligned storage to store the types.
+ Add support for C++0x initializer lists where they're available.
+ For more detail, see the library changelog.
* Xpressive:
+ basic_regex gets nested syntax_option_flags and value_type typedef, for compatibility with std::basic_regex
+ Ported to Proto v4; Proto v2 at boost/xpressive/proto has been removed.
+ regex_error inherits from boost::exception
Other Changes
* Experimental support for building Boost with CMake has been introduced in this version. For more details see the wiki, Discussion is taking place on the Boost-cmake mailing list.
* Fixed subversion properties for several files. Most notably, unix shell scripts should alway have unix line endings, even in the windows packages.
