+Improved: DoFHandler::renumber_dofs() on parallel::distributed::Triangulation
+would scale linearly with the number of MPI ranks on more than 50k ranks,
+reaching times of more than 10 seconds on 150k ranks. This is now fixed for
+the case the renumbering does not lead to a change in the underlying IndexSet
+field of locally owned unknowns, i.e., in case the numbers merely change
+within each MPI rank but not across them.
