<h3>1.34.1 (24 July 2007)</h3>
<p>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
<a href="http://svn.boost.org/trac/boost/query?status=closed&milestone=Boost+1.34.1">Boost Trac</a>.</p>
<h4>Supported Compilers</h4>
<p>New in this release is improved support for
the IBM XL C/C++ compiler.</p>
<p>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 <a href=
"http://www.boost.org/regression/release/user/">regression
test results</a>.</p>

warnings from Boost headers and other
standards-conforming C++ code. To suppress these
warnings, define the macro
<code>_SCL_SECURE_NO_DEPRECATE</code>.</li>

<h4>New Libraries</h4>
<ul>
<li><span class="library"><a href=
"../doc/html/foreach.html">Foreach Library</a>:</span>
<tt>BOOST_FOREACH</tt> macro for easily iterating
over the elements of a sequence, from Eric
Niebler.</li>
<li><span class="library"><a href=

<li><span class="library"><a href=
"../libs/tr1/index.html">TR1 Library</a>:</span> 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 <code>std::tr1</code>. 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.</li>
<li><span class="library"><a href=
"../doc/html/typeof.html">Typeof
Library</a>:</span> Typeof operator emulation,
from Arkadiy Vertleyb and Peder Holt.</li>

Containers</a> when the containers hold

<li>
<span class="library"><a href=

</li>
<li>
<span class="library"><a href=
"../libs/filesystem/doc/index.htm">Filesystem
Library</a>:</span> Major upgrade in preparation
for submission to the C++ Standards Committee for
TR2. Changes include:
<ul>
<li><a href=
"../libs/filesystem/doc/i18n.html#Internationalization">
Internationalization</a>, provided by class
templates <i>basic_path</i>,
<i>basic_filesystem_error</i>,
<i>basic_directory_iterator</i>, and

recursive directory iterator</a>.</li>
</ul>
</li>
<li><span class="library"><a href=
"../libs/function/index.html">Function
Library</a>:</span> 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,
<code>bind(&X:foo, &x, _1, _2)</code>
requires no heap allocation when placed into a
Boost.Function object.</li>
<li>
<span class="library"><a href=
"../libs/functional/hash/index.html">Functional/Hash
Library</a></span>
<ul>

<h4>Supported Compilers</h4>
<p>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. 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 <a href=

<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>

<h4>Regression tests</h4>
<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=
"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.</p>

<h3>1.31.0 (26 Jan 2004)</h3>
<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
<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.</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>
<h4>Build and Installation</h4>
<ul>
<li>New <a href="getting_started.html">Getting
