<h2>Release 1.43.0</h2>
<h3>bug fixes</h3>
<ul>
<li><a href="https://svn.boost.org/trac/boost/ticket/3968">[3968]</a> fixed coordinate_matrix sort problem on MSVC10
</li>
<li><a href="https://svn.boost.org/trac/boost/ticket/3539">[3539]</a>
changed computation of <code>norm_inf</code> for complex types to match
mathematical definition. <br />
<b>Note:</b> This might cause a performance drop
because now <code>std::abs(z)</code> is called for each vector element.
The old implementation used <code>std::max(std::abs(real(z)),std::abs(imag(z))</code>.
Further <code>norm_inf</code> and <code>norm_1</code> will now return
the same values for complex vector.
</li>
<li><a href="https://svn.boost.org/trac/boost/ticket/3501">[3501]</a> Moved free functions in <code>concepts.hpp</code> into anonymous namespace.
</li>
</ul>
<h2>Release 1.41.1</h2>
<h3>new features</h3>
<ul>
<li>Move semantics of vector/matrix container assignments have been
implemented. They can be enabled by setting
BOOST_UBLAS_MOVE_SEMANTICS. More details are on the <a
href="options.htm">preprocessor options page</a>.
</li>
<li>Introduce new free functions. See <a href="https://svn.boost.org/trac/boost/ticket/3449" target="_blank">[3449]</a>,
the new tests in <tt>libs/numeric/ublas/test</tt> and the inline documentation of the files in <tt>boost/numeric/ublas/operation/</tt>.
</li>
</ul>
<h3>bug fixes</h3>
<ul>
<li><a href="https://svn.boost.org/trac/boost/ticket/3293">[3293]</a> Fix resizing problem in <code>identity_matrix</code>
</li>
<li><a href="https://svn.boost.org/trac/boost/ticket/3499">[3499]</a> Add DefaultConstructible to concept checks
</li>
</ul>
