New Libraries

  • Asio: Portable networking,
    including sockets, timers, hostname resolution and socket iostreams, from
    Chris Kohlhoff.
  • Bimap: Boost.Bimap is a
    bidirectional maps library for C++. With Boost.Bimap you can create associative
    containers in which both types can be used as key, from Matias Capeletto.
  • Circular Buffer: STL
    compliant container also known as ring or cyclic buffer, from Jan Gaspar.
  • Function Types:
    Boost.FunctionTypes
    provides functionality to classify, decompose and synthesize function, function
    pointer, function reference and pointer to member types. From Tobias Schwinger.
  • Fusion:
    Library for working
    with tuples, including various containers, algorithms, etc. From Joel de
    Guzman, Dan Marsden and Tobias Schwinger.
  • GIL:
    Generic Image Library,
    from Lubomir Bourdev and Hailin Jin.
  • Interprocess:
    Shared
    memory, memory mapped files, process-shared mutexes, condition variables,
    containers and allocators, from Ion Gaztañaga.
  • Intrusive:
    Intrusive
    containers and algorithms, from Ion Gaztañaga.
  • Math/Special
    Functions
    :

    A wide selection of mathematical special functions from
    John Maddock, Paul Bristow, Hubert Holin and Xiaogang Zhang.
  • Math/Statistical
    Distributions
    :

    A wide selection of univariate statistical distributions
    and functions that operate on them from John Maddock and Paul Bristow
  • MPI:
    Message Passing Interface
    library, for use in distributed-memory parallel application programming,
    from Douglas Gregor and Matthias Troyer.
  • System:
    Operating system
    support, including the diagnostics support that will be part of the C++0x
    standard library, from Beman Dawes.

Updated Libraries

  • Graph:
    Generic graph
    components and algorithms. Highlights:
    • kolmogorov_max_flow,
      from Stephan Diederich as part of the 2006 Google Summer of Code.
    • read_dimacs_max_flow
      and write_dimacs_max_flow
      for max-flow problems, from Stephan Diederich.
    • read_graphml and write_graphml for GraphML input/output,
      from Tiago de Paula Peixoto.
    • minimum_cycle_ratio and
      maximum_cycle_ratio,
      from Dmitry Bufistov and Andrey Parfenov.
    • boyer_myrvold_planarity_test,
      along with a suite of algorithms for planar graphs, from Aaron Windsor.

    • LEDA Adaptor improvements, from Jens Müller.
  • Hash:
    A TR1 hash
    function object, from Daniel James. Highlights:

    • Support for longlong,
      std::complex.

    • Improved the algorithm for hashing floating point numbers.

    • A few bug and warning fixes.
  • Iostreams: Framework
    for defining streams, stream buffers and i/o filters, from Jonathan Turkanis.
    Highlights:

    • Clarified the semantics of close(). This fixes several bugs but will
      break some existing code. See Release
      Notes
      for details.

    • Numerous other bug fixes and optimizations.
  • Multi Array:

    • Added "dimensionality" compile-time constante to the MultiArray
      concept.

    • For greater control over error situations, uses of C++ assert have been
      replaced with BOOST_ASSERT.

    • Fixed a bug with simultaneous resizing and reindexing.
  • Multi-index Containers:
  • Serialization:
    Boost.Serialization
    has been updated with optimizations for dense arrays.
  • Thread:

    • The Thread library has been updated to be more in line with the C++0x
      working draft.

    • Instances of boost::thread and of the various lock types are now movable.

    • Threads can be interrupted at interruption points.

    • Condition variables can now be used with any type that implements the
      Lockable concept, through the use of boost::condition_variable_any
      (boost::condition is a typedef to boost::condition_variable_any, provided for
      backwards compatibility). boost::condition_variable
      is provided as an optimization, and will only work with boost::unique_lock<boost::mutex>
      (boost::mutex::scoped_lock).

    • Thread IDs are separated from boost::thread, so a thread can obtain it's
      own ID (using boost::this_thread::get_id()),
      and IDs can be used as keys in associative containers, as they have the
      full set of comparison operators.

    • Timeouts are now implemented using the Boost DateTime library, through
      a typedef boost::system_time for absolute timeouts,
      and with support for relative timeouts in many cases. boost::xtime
      is supported for backwards compatibility only.

    • Locks are implemented as publicly accessible templates boost::lock_guard, boost::unique_lock,
      boost::shared_lock, and boost::upgrade_lock,
      which are templated on the type of the mutex. The Lockable concept has
      been extended to include publicly available lock() and unlock() member functions, which are used by
      the lock types.
    • boost::try_mutex has been removed, and the
      functionality subsumed into boost::mutex.
      boost::try_mutex is left as a typedef, but
      is no longer a separate class.
    • boost::recursive_try_mutex has been removed,
      and the functionality subsumed into boost::recursive_mutex.
      boost::recursive_try_mutex is left as a typedef,
      but is no longer a separate class.
    • boost::detail::thread::lock_ops has been removed. Code that
      relies on the lock_ops
      implementation detail will no longer work, as this has been removed,
      as it is no longer necessary now that mutex types now have public lock()
      and unlock()
      member functions.
    • scoped_lock constructors
      with a second parameter of type bool are no longer provided. With previous
      boost releases, boost::mutex::scoped_locksome_lock(some_mutex,false);
      could be used to create a lock object that was associated with a mutex,
      but did not lock it on construction. This facility has now been replaced
      with the constructor that takes a boost::defer_lock_type
      as the second parameter: boost::mutex::scoped_locksome_lock(some_mutex,boost::defer_lock);

    • The broken boost::read_write_mutex has been replaced
      with boost::shared_mutex.
  • Wave: Standards conformant
    implementation of the mandated C99/C++ preprocessor functionality packed
    behind an easy to use iterator interface, from Hartmut Kaiser. Highlights:

    • Added the possibility to continue the preprocessing after an error occured.

    • Added the macro introspection API to the wave::context object.

    • Added threading support to the library.

    • Improved the overall performance by upto 30%.

    • Changed and unified preprocessor hook interface (this is an interface
      breaking change!), added several new preprocessor hook functions.

    • Added serialization support.

    • Added new examples (for instance: Hannibal - a partial C++ parser, by
      Danny Havenith).

    • Added a new lexical analyzer based on Ben Hansons Lexertl library.

    • Fixed a large number of other bugs and problems.
  • Xpressive: Regular
    expressions that can be written as strings or as expression templates, and
    that can refer to each other and themselves recursively with the power of
    context-free grammars, from Eric Niebler. Highlights:

    • Added semantic actions to static regexes. A semantic
      action is code that executes when part of a regular expression matches.

    • Added custom assertions to static regexes. A custom
      assertion is a Boolean predicate that can participate in the regex match.

    • Added named regexes for embedding a static or dynamic
      regex into a dynamic regex. This can be used to create dynamic regex
      grammars.

    • Added named captures to dynamic regexes, like Perl.
