Can 163 be used with ``ctypes`` to pass a PETSc handle. 164 165- Add ``Comm.tompi4py()`` to get a ``mpi4py`` communicator instance. 166 167 168Release 1.2 169=========== 170 171- Update to PETSc 3.2 release. 172 173- Add new ``DM`` class , make ``DA`` inherit from ``DM``. 174 175- Better support for inplace LU/ILU and Cholesky/ICC factorization and 176 factor PC subtypes. 177 178- Now the ``Mat``/``PC``/``KSP``/``SNES``/``TS`` Python subtypes are 179 implemented with Cython. 180 181- Better interaction between Python garbage collector and PETSc 182 objects. 183 184- Support for PEP 3118 and legacy Python's buffer interface. 185 186 187Release 1.1.2 188============= 189 190This is a new-features and bug-fix release. 191 192- Add support for copying and computing complements in ``IS`` 193 (``IS.copy()`` and ``IS.complement()``). 194 195- Add support for coarsening in ``DA`` (``DA.coarsen()``). 196 197- Support for shallow copy and deep copy operations (use ``copy.copy`` 198 and ``copy.deepcopy``). Deep copy is only supported for a bunch of 199 types (``IS``, ``Scatter``, ``Vec``, ``Mat``) 200 201- Support for ``pip install petsc4py`` to download and install PETSc. 202 203 204Release 1.1.1 205============= 206 207This is a new-features and bug-fix release. 208 209- Support for setting PETSC_COMM_WORLD before PETSc initialization. 210 211- Support for coordinates, refinement and interpolation in DA. Many 212 thanks to Blaise Bourdin. 213 214- Workaround build failures when PETSc is built with *mpiuni*. 215 216- Workaround GIL-related APIs for non-threaded Python builds. 217 218 219Release 1.1 220=========== 221 222- Update for API cleanups, changes, and new calls in PETSc 3.1 and 223 some other missing features. 224 225- Add support for Jed Brown's THETA an GL timestepper implementations. 226 227- Fix the annoying issues related to Open MPI shared libraries 228 dependencies and Python dynamic loading. 229 230- Many minor bug-fixes. Many thanks to Ethan Coon, Dmitry Karpeev, 231 Juha Jaykka, and Michele De Stefano. 232 233 234Release 1.0.3 235============= 236 237This is a bug-fix release. 238 239- Added a quick fix to solve build issues. The macro __SDIR__ is no 240 longer passed to the compiler in the command line. 241 242 243Release 1.0.2 244============= 245 246This is a new-features and bug-fix release. 247 248- Now ``petsc4py`` works against core PETSc built with complex 249 scalars. 250 251- Added support for PETSc logging features like stages, classes and 252 events. Stages and events support the context manager interface 253 (``with`` statement). 254 255- Documentation generated with Epydoc and Sphinx is now included in 256 the release tarball. 257 258- Removed enumeration-like classes from the ``petsc4py.PETSc`` module 259 namespace. For example, now you have to use ``PETSc.KSP.Type`` 260 instead of ``PETSc.KSPType``. 261 262- The ``PETSc.IS`` to ``numpy.ndarray`` conversion now works for 263 stride and block index sets. 264 265- Implemented a more robust import machinery for multi-arch 266 ``petsc4py`` installations. Now a wrong value in the ``PETSC_ARCH`` 267 environmental variable emit a warning (instead of failing) at import 268 time. 269 270- The unittest-based testsuite now can run under ``nose`` with its 271 default options. 272 273- Removed the dependency on ``numpy.distutils``, just use core Python 274 ``distutils``. 275 276 277Release 1.0.1 278============= 279 280This is a bug-fix release. Compile Cython-generated C sources with 281``-Wwrite-strings`` removed, as this flag (inherited from PETSc) made 282GCC emit a lot of (harmless but annoying) warnings about conversion of 283string literals to non-const char pointers. 284 285 286Release 1.0.0 287============= 288 289This is the fist release of the all-new, Cython-based, implementation 290of *PETSc for Python*. 291
