  1. + New: Since the MA27 sparse direct solver uses Fortran common blocks, it + was previously impossible to run several instances of this solver in + parallel, in a multihreaded environment. To solve this problem, the + SparseDirectMA27 class now has a detached + mode, in which it forks off a separate program that will do the + computations using this solver. The actual operations are therefore + distributed to distint programs that have separate address spaces. This + allows to have as many concurrent instances of this solver in parallel + as you want. For more information, read the documentation of the + SparseDirectMA27 class. +

  2. Changed: The classes PreconditionBlock, PreconditionBlockJacobi, PreconditionBlockSOR, and PreconditionBlockSSOR have changed their - template signature. The first template argument is now the matrix - type, not just a number type. -

  3. New: class BlockVector has a - function collect_sizes(), very much as - BlockSparsityPattern. This allows - updating internal structures after blocks have been resized. -

  4. New: class SparseMatrix has an - STL-conforming const_iterator and - functions begin() and end() for looping through all existing - entries. Furthermore, begin(row) and - end(row) allow looping through all - entries of a single line. -
