+  New: There is now a class TrilinosWrappers::SparsityPattern that allows to 
+  construct distributed sparsity patterns that can be used for initializing 
+  Trilinos sparse matrices. This means that for large problems on several 
+  MPI processors the memory requirements are reduced and the initialization 
+  speed is increased.
