                    <h4>Important - New Toolset Names</h4>

                    <p>The names of some the Boost.Build <a href=
                    "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=
                    "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>

                    <p>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=

                    <h4>New License</h4>

                    <p>A unified <a href="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

                    various legal documents.</p>

                    <p><strong>Note:</strong> Many of the Boost libraries are
                    still using earlier licenses, though all conform to the
                    <a href="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.</p>
