- update to version 2.10.0
  * Improve testing support on Laplacian matrices with an optional
    diagonal regularization parameter.
  * Base the implementation of VariableBlockVector on std::vector
    as the storage type. Note that this prevents from using bool
    as block type that was possible before.
  * A method BCRSMatrix::setIndicesNoSort() was added. Similar
    to BCRSMatrix::setIndices() this allows to insert all indices
    of a row at once, but - in contrast to the latter - does not
    sort them. This allows to speed up insertion if indices are
    already sorted.
  * UMFPACK is extended to arbitrary blocked matrix structures.
    This includes MultiTypeBlockMatrix. The external interface
    is unchanged.
  * The internal storage in MatrixIndexSet was changed from
    std::set to a sorted std::vector to improve performance. The
    stored index type was changed from std::size_t to uint32_t to
    reduce memory consumption and improve performance. Hence,
    MatrixIndexSet can no longer be used for very large matrices
    with more than 2^32 columns.
  * Added flag 'useFixedOrder' to the coarsen method of AMGs
    ParallelIndicesCoarsener. If set to true, during the creation
    of the coarser matrix (by accumulation and restriction
    to fewer processes) the coarse matrix rows are ordered in a
    fixed manner, making parallel runs reproducible; the runtime
    is possibly not ideal though.

- Update to 2.9.0
  * Add const qualifier to LinearOperator and ScalarProduct in
    IterativeSolver. In particular, the constructors of iterative
    solvers have changed.
  * Solvers are more robust if used with multiple right-hand sides
    and one lane starts with the exact solution.
  * Added a function to write nested matrices as SVG
    objects: writeSVGMatrix(...)
  * MultiTypeBlockVector uses now std::common_type of the entries
    for the field_type. The old double default is replaced by
    Std::nonesuch of an empty MultiTypeBlockVector.
  * All vector implementations require a FieldTraits class
    specialization to export field_type and real_type in order to
    work with blocked ISTL vector types.
  * MINRES: The algorithm computes the preconditioned defect
    during the iterations. However, the initial defect was computed
    as the defect of the original/non-preconditioned system. This
    is now changed so that the initial defect is also computed as
    the preconditioned defect (this is also in line with GMRes).
  * The Cholmod class now provides access to the cholmod_factor
    class that is used by CHOLMOD itself to store the Cholesky
    factor.
  * You can now multiply objects of type ScaledIdentityMatrix
    by scalars using operator*.
  * You can now use std::tuple_element to get the types of
    MultiTypeBlockVector entries and MultiTypeBlockMatrix rows.
  * The SPQR solver can now work with non-square matrices.
