<li>For ordered and hashed indices, <code>erase(it)</code> and
<code>erase(first,last)</code> now return an iterator to the element
following those being deleted (previously nothing was returned), in
accordance with the C++ Standard Library
<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-defects.html#130">Defect
Report 130</a> and issue 6.19 of TR1

List</a>.
</li>
<li>Boost.MultiIndex offers the usual guarantees with respect to
multithreading code provided by most STL implementations:
<ol>
<li>Concurrent access to different containers is safe.</li>
<li>Concurrent read-only access to the same container is safe.</li>
</ol>
In previous versions of the library, the latter guarantee was not properly
maintained if the <a href="advanced_topics.html#safe_mode">safe
mode</a> was set. This problem has been fixed now.
</li>
<li>Maintenance fixes.</li>
</ul>
</p>
<h2><a name="boost_1_33">Boost 1.33 release</a></h2>
<p>
<ul>
<li>Added <a href="advanced_topics.html#hashed_indices">hashed indices</a>,
whose interface is based on the specification for unordered associative
containers by the C++ Standard Library Technical Report (TR1).
</li>
<li>Added <a href="advanced_topics.html#serialization">serialization support</a>
for <a href="../../serialization/index.html">Boost.Serialization</a>.
</li>
<li>Destruction of <code>multi_index_container</code>s and <code>clear</code>
memfuns now perform faster.
</li>
<li>Internal changes aimed at reducing the length of symbol names generated
by the compiler; cuts of up to a 50% can be achieved with respect to the
Boost 1.32 release. This results in much shorter and more readable error
messages and has also a beneficial impact on compilers with strict limits on
symbol name lengths. Additionally, a section on further
<a href="compiler_specifics.html#symbol_reduction">reduction of symbol name
lengths</a> has been added.
</li>
<li>Restructured some parts of the documentation, new examples.</li>
<li>Maintenance fixes.</li>
</ul>
