+Changed: The parallel triangulation classes parallel::shared::Triangulation
+and parallel::distributed::Triangulation used to duplicate the MPI
+communicator given to the constructor, which could lead to access-after-free
+problems in Trilinos data structures based on this communicator that stayed
+alive longer than the Triangulation. The new implementation simply uses the
+MPI communicator provided by the user and thus avoids these problems. It is
+the user's responsibility to make sure MPI_Comm_free is only called when all
+data structures initialized with it are deleted.
