<p>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.</p>
<p>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 <a href="http://www.open-std.org/jtc1/sc22/wg21/">
C++ Standards Committee</a>'s upcoming <a href="http://open-std.org/jtc1/sc22/wg21/docs/library_technical_report.html">
C++ Standard Library Technical Report</a> as a
step toward becoming part of a future C++ Standard.</p>
<p>Although Boost was begun by members of the C++ Standards Committee Library
Working Group, participation has expanded to include thousands of
programmers from the C++ community at large.</p>
<h2><a name="Membership">Participation</a></h2>
<p>If you are interested in participating in Boost, please join
our main <a href="more/mailing_lists.htm#main">developers mailing list</a>. Discussions
are highly technical, and list members are encouraged to participate in formal
reviews of proposed libraries. There is also a
<a href="more/mailing_lists.htm#users">users mailing list</a>,
and several <a href="more/mailing_lists.htm#projects">
project specific lists</a>.</p>
<p>Both the main Boost developers list and the users list are also accessible as <a href="more/mailing_lists.htm">
newsgroups</a>.</p>

<h3>November 19, 2004 - Version 1.32.0</h3>
<h4>Important - New Toolset Names</h4>
<p>The names of some the Boost.Build
<a href="more/getting_started.html#Tools">toolsets</a>
have been changed to remove the "<code>.</code>" (dot) character and to fix some
other naming inconsistencies. For example, <code>vc7.1</code> toolset was renamed
to become <code>vc-7_1</code>. Please refer to the
<a href="more/getting_started.html#Tools">Supported Toolsets</a> section
of the installation guide for the complete list of the current toolset names.
This change was made as a part of the effort to make the Boost distribution
compatible with ISO 9660 level 2 requirements.</p>

<h4>Regression tests</h4>
This release has been extensively tested on a variety of different compilers and platforms.
It is known to contain no regressions against the previous reference release on the
compilers and configurations tested. Please refer to the corresponding
<a href="http://www.meta-comm.com/engineering/boost-regression/1_32_0/index.html">regression reports</a> to see how well your
compiler performs on the new Boost codebase.

<h3>January 26, 2004 - Version 1.31.0</h3>
<h4>New License</h4>
a unified <a href="more/license_info.html">Boost Software License</a> 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 <a href="http://cyber.law.harvard.edu/people/cabell/index.html">
Diane Cabell</a>, Director, Clinical Programs, <a href="http://cyber.law.harvard.edu">
Berkman Center for Internet & Society</a>, Harvard Law School. <a href="http://www.nixonpeabody.com/attorneys_detail1.asp?ID=121">
Devin Smith</a>, attorney, <a href="http://www.nixonpeabody.com/default.asp">Nixon
Peabody LLP</a>, wrote the Boost License. Eva Chan, Harvard Law School,
contributed analysis of issues and drafts of various legal documents.
<blockquote>
<b>Please Note:</b> Many of the Boost
libraries are still using earlier
licenses, though all conform to the <a
href="more/lib_guide.htm#license">Boost
License Requirements</a>. After this
release we will begin an effort to
move toward uniform use of the new
license.
</blockquote>

<h3>August 12, 2003 - <b>ALERT</b></h3>
<p>
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.
<p>Until then, you may want to get the <code>RC_1_30_0</code> branch (which, with
only very slight modification, will become version 1.30.2) from our <a href="more/getting_started.html#CVS">
CVS</a> repository or the <a href="more/getting_started.html#CVS">CVS mirror</a>
at <a href="http://www.boost-consulting.com">Boost Consulting</a>
.
