Release Notes for PyTrilinos 4.2 (Trilinos 10.0)
================================================

General notes for PyTrilinos:

  * Converted to CMake build system

  * Added const-correctness for char* function arguments.  This
    improves compatibility with newer gnu compilers.

PyTrilinos.Teuchos notes:

  * LabeledObject and Describable classes converted to director
    classes so that virtual methods can be overridden in python.

PyTrilinos.EpetraExt notes:

  * Added wrappers for ModelEvaluator and all associated classes

PyTrilinos.Komplex notes:

  * Added Komplex module

PyTrilinos.Pliris notes:

  * Added Pliris module

PyTrilinos.NOX notes:

  * Improved robustness of NOX sub-packages

  * Added wrappers for ModelEvaluatorInterface class

  * Added default builder functions:

    + defaultNonlinearParameters()
    + defaultGroup()
    + defaultStatusTest()
    + defaultSolver()



Release Notes for PyTrilinos 4.1 (Trilinos 9.0)
===============================================

General notes for PyTrilinos:

  * Added auto-generated documentation.

  * Standardized and upgraded PyTrilinos module docstrings.

  * Improved exception handling.

  * Fixed problem with patch for numpy 0.9.8 bug; moved fix for python
    2.5 compatibility into file where it is directly needed.

  * Fixed problem some PyTrilinos modules had interpreting elements of
    numpy arrays as integers.

  * Added logic to python extension module builds so that compile
    flags -ansi and -pedantic will be ignored.

  * Fixed some incompatibilities between the generated code from swig
    version 1.3.35 and earlier versions.

  * Better error checking when a python argument is converted to an
    array of char* strings.

  * Eliminated certain runtime type information errors by moving to
    shared laibraries, thus ensuring that no symbols get duplicated.

  * Added C89 compliance.

  * Changed PyTrilinos/__init__.py to alter the python dlopen flags so
    that symbols are shared across all of the PyTrilinos extension
    modules.  This fixed many bugs associated with symbols crossing
    shared library boundaries.

  * Added fixes for installation on Fedora Core.

PyTrilinos.Teuchos notes:

  * Added support for Teuchos::Comm, Teuchos::SerialComm,
    Teuchos::MpiComm and Teuchos::DefaultComm, including tests.

PyTrilinos.Epetra notes:

  * Added support for the Epetra.Comm Broadcast method with string
    data, including additions to testEpetra_Comm.py to test the
    capability.  Since these are in-place, users must use numpy arrays
    of strings.

  * Some PyTrilinos.Epetra MPI reduction operations were returning
    garbage.  This was fixed by clearing out those arrays prior to the
    call.

  * Epetra.Finalize() (called automatically when the Epetra module is
    destroyed) now checks MPI_Finalized() before calling
    MPI_Finalize().  This should help it play nice with Teuchos MPI
    support.

  * Upgraded Epetra.FEVector to reflect its new multivector nature.

  * Fixed Epetra.Vector and Epetra.MultiVector objects so that slices
    return new Epetra.[Multi]Vector objects with accurate Maps.

PyTrilinos.AztecOO notes:

  * Improved the AztecOO wrappers for better compatibility with older
    versions of numpy.

  * Fixed exAztecOO_Operator.py, exAztecOO_RowMatrix.py and
    exAztecOO_BasicRowMatrix.py example scripts so that they work in
    parallel.

PyTrilinos.ML notes:

  * Updated PyTrilinos.ML to be more robust.

PyTrilinos.NOX notes:

  * Fixed NOX.Solver.myBuildSolver to properly use new Teuchos::Ptr
    templated class.

PyTrilinos.Anasazi notes:

  * Added MPI support to Anasazi wrappers.

  * Updated PyTrilinos w.r.t. changes in Anasazi::SortManager interface.

  * Added support to Anasazi wrappers for extracting eigenvalues and
    eigenvectors.
