1.34.1 (24 July 2007)

+ +

This is a bug fix release addressing many problems with the 1.34.0 release. + It is a recommended upgrade for all users of Boost 1.34.0. For a complete list of fixes see + Boost Trac.

+ +

Supported Compilers

+ +

New in this release is improved support for + the IBM XL C/C++ compiler.

+ +

Boost is tested on a wide range of compilers and + platforms. Since Boost libraries rely on modern C++ + features not available in all compilers, not all + Boost libraries will work with every compiler. + New in this release The + following compilers and platforms have been + extensively tested with Boost, although many other + compilers and platforms will work as well. For more + information, see the regression + test results.

+ + + +

Acknowledgements

+ +

Thomas Witt + managed this release.

+ +

A great number of people contributed their time + and expertise to make this release possible. Special + thanks go to Kim Barrett consolidating Boost.Iostreams changes + from various branches and Rene Rivera for general build and installation + support.

+ +

1.34.0 (12 May 2007)

+

New Libraries

+ +
    +
  • Foreach Library: + BOOST_FOREACH macro for easily iterating + over the elements of a sequence, from Eric + Niebler.
    • + +
  • Statechart + Library: Arbitrarily complex finite state + machines can be implemented in easily readable and + maintainable C++ code, from Andreas Huber.
    • + +
  • TR1 Library: An + implementation of the C++ Technical Report on + Standard Library Extensions, from John Maddock. + This library does not itself implement the TR1 + components, rather it's a thin wrapper that will + include your standard library's TR1 implementation + (if it has one), otherwise it will include the + Boost Library equivalents, and import them into + namespace std::tr1. Highlights + include: Reference Wrappers, Smart Pointers, + result_of, Function Object Binders, Polymorphic + function wrappers, Type Traits, Random Number + Generators and Distributions, Tuples, Fixed Size + Array, Hash Function Objects, Regular Expressions, + and Complex Number Additional Algorithms.
    • + +
  • Typeof + Library: Typeof operator emulation, + from Arkadiy Vertleyb and Peder Holt.
    • + +
  • Xpressive + Library: 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.
    • +
+ +

Updated Libraries

+ +
    + +
  • + Assign + Library: + +
      +
    • Support for + ptr_map<key,T> via the new + function ptr_map_insert()
      • + +
    • Support for initialization of Pointer + Containers when the containers hold + pointers to an abstract base class.
      • +
    +
    • + +
  • + Date_time library: +
      +
    • Support for new US/Canada timezone rules and + other bug fixes. See + Change History + for details. +
      • +
    +
    • + +
  • + Filesystem + Library: Major upgrade in preparation + for submission to the C++ Standards Committee for + TR2. Changes include: + +
      +
    • + Internationalization, provided by class + templates basic_path, + basic_filesystem_error, + basic_directory_iterator, and + basic_directory_entry.
      • + +
    • Simplification + of the path interface by eliminating special + constructors to identify native formats.
      • + +
    • + Rationalization of predicate function + design, including the addition of several new + functions.
      • + +
    • Clearer specification by reference to + POSIX, + the ISO/IEEE Single Unix Standard, with + provisions for Windows and other operating + systems.
      • + +
    • Preservation + of existing user code whenever possible.
      • + +
    • More + efficient directory iteration.
      • + +
    • Addition of a + recursive directory iterator.
      • +
    +
    • + +
  • Function + Library: Boost.Function now implements a + small buffer optimization, which can drastically + improve the performance when copying or + constructing Boost.Function objects storing small + function objects. For instance, + bind(&X:foo, &x, _1, _2) + requires no heap allocation when placed into a + Boost.Function object.
    • + +
  • + Functional/Hash + Library + +
      +
    • Use declarations for standard classes, so + that the library doesn't need to include all of + their headers
      • + +
    • Deprecated the + <boost/functional/hash/*.hpp> + headers.
      • + +
    • Add support for the + BOOST_HASH_NO_EXTENSIONS macro, which + disables the extensions to TR1
      • + +
    • Minor improvements to the hash functions + for floating point numbers.
      • +
    +
    • + +
  • + Graph + Library: + + +
    • + +
  • MultiArray + Library: Boost.MultiArray now by default + provides range-checking for + operator[]. Range checking can be + disabled by defining the macro + BOOST_DISABLE_ASSERTS before including + multi_array.hpp. A bug in + multi_array::resize() related + to storage orders was fixed.
    • + +
  • + Multi-index + Containers Library: + + +
    • + +
  • + Optional Library: + +
      +
    • boost::none_t and boost::none now added to Optional's documentation
      • +
    • Relational operators now directly support arguments of type 'T' and 'none_t'
      • +
    • operator->() now also works with reference types.
      • +
    • Helper functions make_optional(val), make_optional(cond,val) and + get_optional_value_or(opt,alternative_value) added.
      • +
    • Constructor taking a boolean condition (as well as a value) added.
      • +
    • Member function get_value_or(alternative_value) added.
      • +
    • Incompatbility bug with mpl::apply<> fixed.
      • +
    • Converting assignment bug with uninitialized lvalues fixed.
      • +
    +
    • + +
  • + Parameter + Library: + +
      +
    • Every ArgumentPack is now a valid MPL + Forward Sequence.
      • + +
    • Support for unnamed arguments (those whose + keyword is deduced from their types) is + added.
      • + +
    • Support for named and unnamed template + arguments is added.
      • + +
    • New overload generation macros solve the + + forwarding problem directly.
      • + +
    • See also the Python library changes, + below.
      • +
    +
    • + +
  • + Pointer Container + Library: + +
      +
    • Support for serialization via Boost.Serialization.
      • + +
    • Exceptions can be disabled by defining the + macro BOOST_PTR_CONTAINER_NO_EXCEPTIONS before + including any header. This macro is defined by + default if BOOST_NO_EXCEPTIONS is defined.
      • + +
    • Additional + std::auto_ptr<T> overloads + added s.t. one can also pass + std::auto_ptr<T> instead of + only T* arguments to member + functions.
      • + +
    • transfer() now has weaker + requirements s.t. one can transfer objects from + ptr_container<Derived> to + ptr_container<Base>,
      • +
    +
    • + +
  • + Python + Library: + +
      +
    • Boost.Python now automatically appends C++ + signatures to docstrings. The new + docstring_options.hpp header is + available to control the content of + docstrings.
      • + +
    • + stl_input_iterator, for + turning a Python iterable object into an STL + input iterator, from Eric Niebler.
      • + +
    • Support for void* conversions + is added.
      • + +
    • Integrated support for wrapping C++ + functions built with the parameter library; + keyword names are automatically known to + docsstrings.
      • + +
    • Enhancements to the API for better embedding support + (boost::python::import(), + boost::python::exec(), + and boost::python::exec_file()).
      • + +
    +
    • + +
  • Signals Library: + More improvements to signal invocation performance from + Robert Zeh.
    • + +
  • + Smart + Pointers Library: + + +

      • +
    • join
      • +
    • + New comparison predicates is_less, is_not_greater. +
      • +
    • + Negative indexes support (like Perl) in various algorihtms + (*_head/tail, *_nth). +
      • +
    +
    • +
  • + Wave + Library: + +
      +
    • Wave now correctly recognizes pp-number + tokens as mandated by the C++ Standard, which + are converted to C++ tokens right before they + are returned from the library.
      • + +
    • Several new preprocessing hooks have been + added. For a complete description please refer + to the related documentation page: The + Context Policy.
      • + +
    • Shared library (dll) support has been added + for the generated Wave libraries.
      • + +
    • The overall error handling has been + improved. It is now possible to recover and + continue after an error or a warning was + issued.
      • + +
    • Support for optional comment and/or full + whitespace preservation in the generated output + stream has been added.
      • + +
    • The Wave library now performs automatic + include guard detection to avoid accessing header + files more than once, if appropriate.
      • + +
    • Full interactive mode has been added to the Wave + tool. Now the Wave tool can be used just like Python + or Perl for instance to interactively try out your + BOOST_PP macros. Additionally it is now possible to + load and save the current state of an interactive session + (macro tables et.al.).
      • + +
    • The overall performance has been improved by upto + 40-60%, depending on the concrete files to process.
      • + +
    • Support for new pragmas has been added allowing to + control certain library features from inside the + preprocessed sources (partial output redirection, + control of generated whitespace and #line directives).
      • + +
