+<li> Improved: The iterator class of the deal.II SparseMatrix class
+and SparsityPattern have been revised for performance. Iterating over
+a row of the matrix and querying the column index and the value is now
+similarly fast as iterating over a vector.

 <li> New: A new overload of BlockMatrixBase::add allows to add one block
 matrix to another, with a scaling factor.
