<h2><a name="boost_1_58">Boost 1.58 release</a></h2>
<p>
<ul>
<li>Added hash support both with <code>std::hash</code> and
<a href="../../../doc/html/hash.html"><code>boost::hash</code></a>. This
can be optionally <a href="reference/flyweight.html#disable_hash_support">disabled</a>
to avoid clashes with legacy code where this support has already been defined by
the user.
</li>
<li>Maintenance fixes.</li>
</ul>
</p>
<h2><a name="boost_1_57">Boost 1.57 release</a></h2>
<p>
<ul>
<li>Added serialization support via
<a href="../../serialization/index.html">Boost Serialization</a>.
</li>
<li>
<code>flyweight</code> default constructor was made <code>explicit</code> in
Boost 1.56, which introduces a regression in some
<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_active.html#1518">initialization
scenarios</a>. The former non-<code>explicit</code>
default constructor has been restored
(ticket <a href="https://svn.boost.org/trac/boost/ticket/10439">#10439</a>).
</li>
</ul>
</p>
<h2><a name="boost_1_56">Boost 1.56 release</a></h2>
<p>
<ul>
<li>In compilers with variadic template support, <code>boost::flyweight&lt;T&gt;</code> now provides
a perfectly forwarding constructor to <code>T::T</code> (previously an emulation
was used).</li>
<li><code>flyweight</code> now replicates the initializer-list constructors and assignment
operators of its underlying type.</li>
<li>Fixed intermodule static initialization problem
(ticket <a href="https://svn.boost.org/trac/boost/ticket/9553">#9553</a>).</li>
<li>Maintenance fixes.</li>
</ul>
</p>
<h2><a name="boost_1_55">Boost 1.55 release</a></h2>
<p>
<ul>
<li>Maintenance fixes.</li>
</ul>
</p>
<h2><a name="boost_1_45">Boost 1.45 release</a></h2>
<p>
<ul>
<li>Fixed a hanging problem with
<a href="tutorial/configuration.html#intermodule_holder"><code>intermodule_holder</code></a>
in Win32 platforms related to a Boost.Interprocess issue described at
ticket <a href="https://svn.boost.org/trac/boost/ticket/4606">#4606</a>.
</li>
<li>Removed an internal assertion incompatible with program termination
via <code>std::exit</code>.
</li>
</ul>
</p>
<h2><a name="boost_1_44">Boost 1.44 release</a></h2>
<p>
<ul>
<li>Fixed an incorrect mode of usage of Boost.Variant in
<a href="examples.html#example3">one of the examples</a>.
</li>
</ul>
</p>
<h2><a name="boost_1_40">Boost 1.40 release</a></h2>
<p>
<ul>
<li>Maintenance fixes.</li>
</ul>
</p>
<h2><a name="boost_1_39">Boost 1.39 release</a></h2>
<p>
<ul>
<li><a name="refcounted_bug">The <a href="tutorial/configuration.html#refcounted"><code>refcounted</code></a>
component was not thread-safe due to an incorrect implementation and could deadlock
under heavy usage conditions. This problem has been corrected.</a>
</li>
</ul>
</p>
<h2><a name="boost_1_38">Boost 1.38 release</a></h2>
<p>
<ul>
<li>Initial release of Boost.Flyweight.</li>
</ul>
