  1. + Changed: The MatrixTools::local_apply_boundary_values function + used to set the diagonal entries of boundary nodes to one. This is a + really bad choice, and the algorithm we use now is much better. There + are still a few problems when using this function for matrices that + will be solved as a Schur complement; there is nothing we can do in + that function in these cases, since we are lacking fundamental pieces + of information, but the cases where this applies and the strategies to + work with this problem anyway are now well documented in the + documentation of the MatrixTools class. +

  2. Fixed: The GridGenerator::cylinder_shell function generated cells that were all inside-out, i.e. had negative
