+       Changed: Embedding and restriction matrices for intergrid transfer are
+       now computed in the constructor of most elements, rather than taken from
+       precomputed and tabulated values. This removes restrictions on which
+       elements are available since the old tables were only precomputed for
+       certain polynomial degrees and are now available for all.

+
+  <li> <p> 
+       New: Finite elements got a function <code
+       class="member">get_interpolation_matrix</class>, with which they can
+       compute interpolations between different finite elements. Most will use
+       this to compute interpolations between finite elements of the same kind
+       but different polynomial degrees. The <code
+       class="member">FETools::get_interpolation_matrix</code> makes use of
+       this function if it implements the desired interpolation, and falls back
+       to the old algorithm if this is not the case.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
