  1. + Extend: DoFTools::extract_boundary_dofs + now allows to also specify which boundary conditions shall be + considered. +
    + (WB 2000/12/04) +

  2. + New: some arguments of the functions + DoFHandler::n_boundary_dofs, + DoFTools::extract_boundary_dofs, + and + DoFTools::map_dof_to_boundary_indices + are changed from list to + set, since that resembles more + closely the purpose of the parameter, and makes computations + slightly faster. +
    + (WB 2000/12/04) +

  3. New: almost all classes that store data now have a function memory_consumption that returns an
