 <ol>
+  <li> <p> Fixed: The <code class="class">SparseMatrix</code> iterator classes
+       had various interesting bugs when rows of the matrix were completely
+       empty. These should now be fixed.

   <li> <p> New: The <code class="class">SparsityPattern</code> class now also
        has an iterator class that allows to walk over all nonzero entries of a
        sparsity pattern.
