 <ol>
+  <li> Improved: The methods ConstraintMatrix::distribute_local_to_global
+  now use scratch data that is private to each thread instead of allocating
+  it for every cell anew. This gives better performance, in particular in
+  parallel, of these operations, while maintaining thread-safety (when
+  accessing non-overlapping rows, no race condition can exist).

   <li> Improved: When attempting operations such as FEValues::get_function_values()
   or FEValues::shape_value(), the FEValues object needs to know that what these
   functions return has been computed previously. What is computed is specified

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.
