  1. + New: For recognizing a diverging solver before the maximum + number of steps is reached, SolverControl returns failure also if the residual increases + the start residual by a specific factor. This factor is given + to the SolverControl by the set_failure_criterion function. After + calling the latter function the checking of this additional + failure criterion may again be disabled by calling clear_failure_criterion. +
