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).
Quickbook:

  - 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.

Version 1.38.0

Sun, 08 Feb 2009 12:00:00 GMT

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

Accumulators:
- Add rolling_sum, rolling_count and rolling_mean accumulators.
Any:
- Use a by-value argument for operator= (#2311).
Asio:
- Improved compatibility with some Windows firewall software.
- Ensured arguments to windows::overlapped_ptr::complete() are correctly passed to the completion handler (#2614).
- Fixed a link problem and multicast failure on QNX (#2504, #2530).
- Fixed a compile error in SSL support on MinGW / g++ 3.4.5.
- Drop back to using a pipe for notification if eventfd is not available at runtime on Linux (#2683).
- Various minor bug and documentation fixes (#2534, #2541, #2607, #2617, #2619)
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 Travelling 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 functions 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 functions 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 always have unix line endings, even in the windows packages.
