  23 <h3>improvements</h3>

  25 <ul>
  26 <li><a href="https://svn.boost.org/trac/boost/ticket/4024">[4024]</a> improve performance of inplace_solve</li>
  27 <li><a href="https://svn.boost.org/trac/boost/ticket/6511">[6511]</a> Division by scalar should use enable_if&lt;&gt;</li>
  28 <li><a href="https://svn.boost.org/trac/boost/ticket/7297">[7297]</a> Make the free functions 'num_columns' and 'num_rows' support the uBLAS traits system and better work with expression types</li>
  29 </ul>

  31 <h3>bug fixes</h3>
  32
  33 <ul>
  34 <li><a href="https://svn.boost.org/trac/boost/ticket/7296">[7296]</a> fixes and improvements to test utility functions</li>
  35 <li><a href="https://svn.boost.org/trac/boost/ticket/7363">[7363]</a> fixed coordinate_matrix::sort() for gcc 4.7 and others</li>

  38 <h2>Release 1.43.0</h2>
  39
  40 <h3>bug fixes</h3>
  41
  42 <ul>
  43 <li><a href="https://svn.boost.org/trac/boost/ticket/3968">[3968]</a> fixed coordinate_matrix sort problem on MSVC10
  44 </li>
  45 <li><a href="https://svn.boost.org/trac/boost/ticket/3539">[3539]</a>
  46         changed computation of <code>norm_inf</code> for complex types to match
  47         mathematical definition. <br />
  48         <b>Note:</b> This might cause a performance drop
  49         because now <code>std::abs(z)</code> is called for each vector element.
  50         The old implementation used <code>std::max(std::abs(real(z)),std::abs(imag(z))</code>.
  51         Further <code>norm_inf</code> and <code>norm_1</code> will now return
  52         the same values for complex vector.
  53 </li>
  54 <li><a href="https://svn.boost.org/trac/boost/ticket/3501">[3501]</a> Moved free functions in <code>concepts.hpp</code> into anonymous namespace.
  55 </li>
  56 </ul>

  58 <h2>Release 1.41.1</h2>
  59
  60 <h3>new features</h3>
  61
  62 <ul>
  63 <li>Move semantics of vector/matrix container assignments have been
  64 implemented. They can be enabled by setting
  65 BOOST_UBLAS_MOVE_SEMANTICS. More details are on the <a
  66 href="options.html">preprocessor options page</a>.
  67 </li>
  68 <li>Introduce new free functions. See <a href="https://svn.boost.org/trac/boost/ticket/3449" target="_blank">[3449]</a>,
  69 the new tests in <tt>libs/numeric/ublas/test</tt> and the inline documentation of the files in <tt>boost/numeric/ublas/operation/</tt>.
