                                <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. One goal is to 
                                establish &quot;existing practice&quot; and provide 
                                reference implementations so that the Boost 
                                libraries are suitable for eventual 
                                standardization. Several Boost libraries will be 
                                included in the <a href="http://anubis.dkuug.dk/jtc1/sc22/wg21/">

                                <p>Although Boost was begun by members of the C++ Standards Committee Library 
                                    Working Group, membership has expanded to include nearly two thousand 
                                programmers from the C++ community at large.</p>

                                <p>August 12, 2003 - <b>ALERT</b></p>

                                <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                                withdrawn from the website.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

                                <p>August 4, 2003 - Version 1.30.1 (bugfix release)</p>

                                <p>Fixes were made to the following libraries:</p>

                                <ul>
                                  <li>The <a href="libs/lambda/doc/index.html">Boost.Lambda</a> library is now
                                  usable with gcc-2.95.2
                                  <li><a href="libs/spirit/index.html">Boost.Spirit</a>:

                                    <li>Fixed. Using MSVC++6 (SP5), calling the assign action with a string
                                    value on parsers using the file_iterator will not work.
                                    <li>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.
                                    <li>Fixed: There is a bug in the <code>range_run&lt;CharT&gt;::set
                                    (range&lt;CharT&gt; const&amp; r)</code> function in
                                    &quot;boost/spirit/utility/impl/chset/range_run.ipp&quot;.
                                    <li>Fixed: handling of trailing whitespace bug (ast_parse/pt_parse related)
                                    <li>Fixed: comment_p and end of data bug
                                    <li>Fixed: Most trailing space bug

                                    <li>Fixed: <code>impl::detach_clear</code> bug
                                    <li>Fixed: mismatch closure return type bug
                                    <li>Fixed: <code>access_node_d[]</code> and <code>access_match_d[]</code>
                                    iterator bugs
                                    <li>Fixed a bug regarding threadsafety of Phoenix/Spirit closures.
                                   </ul>
                                  <li>The Boost Template <a href="libs/mpl/doc/index.html">Metaprogramming
