Add Log.{begin|view|destroy}().
Add Mat.SOR() and Mat.SORType.
Add DMPlex.createCoarsePointIS().
Add LGMap.createSF().
Add SNES.getVIInactiveSet().
Add Vec.isaxpy().
Add PC.setReusePreconditioner().
Return correct type in DM.getCoordinateDM().
Fix SWIG wrappers to handle 64bit PetscInt.
Fix linker flags for Python from Fink.
Update to PETSc 3.5 release.
Update to PETSc 3.4 release.
Add support for DMComposite and DMPlex.
Change Mat.getSizes() to return ((m,M),(n,N)).
Fix Options.getAll() mishandling values with negative numbers.
Minor backward compatibility fix for PETSc 3.2 .
Minor bugfix for TSPYTHON subtype.
Update to PETSc 3.3 release.
Change Vec.getLocalForm() to Vec.localForm() for use with context manager and add Vec.setMPIGhost().
Add AO.createMemoryScalable() and LGMap.block() / LGMap.unblock()
Add Object.handle property (C pointer as a Python integer). Can be used with ctypes to pass a PETSc handle.
Add Comm.tompi4py() to get a mpi4py communicator instance.
Update to PETSc 3.2 release.
Add new DM class , make DA inherit from DM.
Better support for inplace LU/ILU and Cholesky/ICC factorization and factor PC subtypes.
Now the Mat/PC/KSP/SNES/TS Python subtypes are implemented with Cython.
Better interaction between Python garbage collector and PETSc objects.
Support for PEP 3118 and legacy Python's buffer interface.
This is a new-features and bug-fix release.
Add support for copying and computing complements in IS (IS.copy() and IS.complement()).
Add support for coarsening in DA (DA.coarsen()).
Support for shallow copy and deep copy operations (use copy.copy and copy.deepcopy). Deep copy is only supported for a bunch of types (IS, Scatter, Vec, Mat)
Support for pip install petsc4py to download and install PETSc.
This is a new-features and bug-fix release.
Support for setting PETSC_COMM_WORLD before PETSc initialization.
Support for coordinates, refinement and interpolation in DA. Many thanks to Blaise Bourdin.
Workaround build failures when PETSc is built with mpiuni.
Workaround GIL-related APIs for non-threaded Python builds.
Update for API cleanups, changes, and new calls in PETSc 3.1 and some other missing features.
Add support for Jed Brown's THETA an GL timestepper implementations.
Fix the annoying issues related to Open MPI shared libraries dependencies and Python dynamic loading.
Many minor bug-fixes. Many thanks to Ethan Coon, Dmitry Karpeev, Juha Jaykka, and Michele De Stefano.
This is a bug-fix release.
Added a quick fix to solve build issues. The macro __SDIR__ is no longer passed to the compiler in the command line.
This is a new-features and bug-fix release.
Now petsc4py works against core PETSc built with complex scalars.
Added support for PETSc logging features like stages, classes and events. Stages and events support the context manager interface (with statement).
Documentation generated with Epydoc and Sphinx is now included in the release tarball.
Removed enumeration-like classes from the petsc4py.PETSc module namespace. For example, now you have to use PETSc.KSP.Type instead of PETSc.KSPType.
The PETSc.IS to numpy.ndarray conversion now works for stride and block index sets.
Implemented a more robust import machinery for multi-arch petsc4py installations. Now a wrong value in the PETSC_ARCH environmental variable emit a warning (instead of failing) at import time.
The unittest-based testsuite now can run under nose with its default options.
Removed the dependency on numpy.distutils, just use core Python distutils.
This is a bug-fix release. Compile Cython-generated C sources with -Wwrite-strings removed, as this flag (inherited from PETSc) made GCC emit a lot of (harmless but annoying) warnings about conversion of string literals to non-const char pointers.
This is the fist release of the all-new, Cython-based, implementation of PETSc for Python.
