The Boost web site provides free peer-reviewed portable C++ source libraries.
The emphasis is on libraries which work well with the C++ Standard Library.
The libraries are intended to be widely useful, and are
in regular use by thousands of programmers across a
broad spectrum of applications.
A further
goal is to establish "existing practice" and provide reference implementations
so that Boost libraries are suitable for eventual standardization.
Ten
Boost libraries will be included in the
C++ Standards Committee's upcoming
C++ Standard Library Technical Report as a
step toward becoming part of a future C++ Standard.
Although Boost was begun by members of the C++ Standards Committee Library
Working Group, participation has expanded to include thousands
programmers from the C++ community at large.
If you are interested in participating in Boost, please join
our main developers mailing list. Discussions
are highly technical, and list members are encouraged to participate in formal
reviews of proposed libraries. There is also a
users mailing list,
and several
project specific lists.
Both the main Boost developers list and the users list are also accessible as
newsgroups.

January 26, 2004 - Version 1.31.0
New License
A unified Boost Software License has been
developed and will gradually replace the individual licenses for most Boost libraries.
The new license offers better legal protection for both users and developers,
and should speed user's legal reviews of Boost libraries. Dave Abrahams led the
Boost effort to develop better licensing. The legal team was led by
Diane Cabell, Director, Clinical Programs,
Berkman Center for Internet & Society, Harvard Law School.
Devin Smith, attorney, Nixon
Peabody LLP, wrote the Boost License. Eva Chan, Harvard Law School,
contributed analysis of issues and drafts of various legal documents.
Please Note: Many of the Boost
libraries are still using earlier
licenses, though all conform to the Boost
License Requirements. After this
release we will begin an effort to
move toward uniform use of the new
license.
Build and Installation
-
New Getting
Started procedures ease download and
installation, from Rene Rivera and others.

Improved support for libraries requiring
separate
compilation, from John Maddock and others.
New Libraries
-
enable_if: Selective
inclusion of function template overloads, from Jaakko Järvi, Jeremiah
Willcock, and Andrew Lumsdaine. This is an important new technique
which exploits the SFINAE
(substitution-failure-is-not-an-error) principle.
-
Variant Library: Safe, generic,
stack-based discriminated union container, from Eric Friedman and Itay
Maman.
Updated Libraries
-
Compose: This library has been
deprecated and will be removed in a future release. Use Bind or Lambda instead.

host of bug fixes, new features, and documentation
improvements. See Date Time
Change History for details.
-
Filesystem Library: Several
added functions, including improved checking for directory and file name
portability.

Iterator Library: Major
version upgrade, with interface as proposed for the C++ library TR,
including an improved
iterator_adaptor design plus
several new components, from David Abrahams, Jeremy Siek, and
Thomas Witt.

template now provides an element-preserving resize operation as well as default
construction (see the reference
manual for more information).

please use Spirit v1.6.x. See Spirit's Site
for more details.

August 12, 2003 - ALERT
Significant problems were found in the 1.30.1 release, so it has been withdrawn
from the website. These problems mostly take the form of missing files due to
an error by the release manager in using CVS to tag the release. We expect to
release Version 1.30.2 in a few days. Stay tuned.
Until then, you may want to get the RC_1_30_0 branch (which, with
only very slight modification, will become version 1.30.2) from our
CVS repository or the CVS mirror
at Boost Consulting
.

Fixed. Using MSVC++6 (SP5), calling the assign action with a string value on
parsers using the file_iterator will not work.
-
Fixed: using assign semantic action in a grammar with a multi_pass iterator
adaptor applied to an std::istream_iterator resulted in a failure to compile
under msvc 7.0.
-
Fixed: There is a bug in the
range_run<CharT>::set (range<CharT>
const& r)
function in "boost/spirit/utility/impl/chset/range_run.ipp".
-
Fixed: handling of trailing whitespace bug (ast_parse/pt_parse related)
