+<li> Changed: DoFTools::make_cell_patches() only accepts block lists
+of type SparsityPattern. The reason is that it has to initialize the
+size of the pattern on distributed triangulations by computing the
+number of locally owned cells. Initialization differs between sparsity
+pattern classes, so no generic function would be possible. On the
+other hand, the block list is an object, which only extends over
+locally owned grid cells and its size can be determined efficiently
+upon initialization. Therefore, SparsityPattern is a good choice here.

PETScWrappers::Vector, PETScWrappers::MPI::Vector,
TrilinosWrappers::Vector, and TrilinosWrappers::MPI::Vector classes
