  1. New: The SolverGMRES now accepts + an AdditionalData parameter + use_default_residual whose default is + true. By setting this flag to false, the + stopping criterion of the left-preconditioned GMRes solver is not + the default preconditioned residual but the normal (unpreconditioned) + residual and visa versa for the right-preconditioned GMRes + solver. Due to a performance loss of the solver this flag should + be set to false only for debugging/testing purposes. +

  2. New: FullMatrix has a function copy_from, copying from sparse matrices. It uses iterators of the sparse matrix classes.
