<h3>1.34.1 (13 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&amp;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>

<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

"../libs/tr1/index.html">TR1 Library</a>:</span> An
implementation of the C++ Technical Report on
Standard Library Extensions, from John Maddock.

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>
