+Changed: The class FEEvaluation now uses a different internal data layout for
+the gradients, exposed via FEEvaluation::begin_gradients(). Now, the entries
+of the partial derivatives in the space directions are placed adjacent in
+memory. The entries of different components are still separated by the entries
+on all points. This change has been made to simplify the access in the
+FEEvaluation::get_gradient() and FEEvaluation::submit_gradient() functions,
+which is especially useful for the case with many FE components. For the
+regular use of FEEvaluation apart from the plain pointers mentioned above,
+there is no change in behavior.

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.
