+Following are a few modifications to the library that unfortunately
+are incompatible with previous versions of the library, but which we
+deem necessary for the future maintainability of the
+library. Unfortunately, some of these changes will require
+modifications to application programs. We apologize for the
+inconvenience this causes.

+ class="member">make_flux_sparsity_pattern</code>, <code
+ class="class">MGTools</code>::<code
+ class="member">make_flux_sparsity_pattern</code> and similar
+ functions in these classes do not receive arguments of type <code
+ class="class">FullMatrix<double></code> anymore. Instead, they
+ get a <code class="class">Table<2,DoFTools::Coupling></code>,
+ which contains more meaningful enums.

+ <li> <p>Changed: <code class="class">Multigrid</code>::<code
+ class="member">Multigrid</code> receives an argument determining the
+ type of multigrid cycle istead of the minimum and maximum
+ levels. The latter were rarely used anyway and can be modified by
+ <code class="member">set_minlevel()</code> and <code
+ class="member">set_maxlevel()</code>
