Can 151 be used with ``ctypes`` to pass a PETSc handle. 152 153- Add ``Comm.tompi4py()`` to get a ``mpi4py`` communicator instance. 154 155 156Release 1.2 157=========== 158 159- Update to PETSc 3.2 release. 160 161- Add new ``DM`` class , make ``DA`` inherit from ``DM``. 162 163- Better support for inplace LU/ILU and Cholesky/ICC factorization and 164 factor PC subtypes. 165 166- Now the ``Mat``/``PC``/``KSP``/``SNES``/``TS`` Python subtypes are 167 implemented with Cython. 168 169- Better interaction between Python garbage collector and PETSc 170 objects. 171 172- Support for PEP 3118 and legacy Python's buffer interface. 173 174 175Release 1.1.2 176============= 177 178This is a new-features and bug-fix release. 179 180- Add support for copying and computing complements in ``IS`` 181 (``IS.copy()`` and ``IS.complement()``). 182 183- Add support for coarsening in ``DA`` (``DA.coarsen()``). 184 185- Support for shallow copy and deep copy operations (use ``copy.copy`` 186 and ``copy.deepcopy``). Deep copy is only supported for a bunch of 187 types (``IS``, ``Scatter``, ``Vec``, ``Mat``) 188 189- Support for ``pip install petsc4py`` to download and install PETSc. 190 191 192Release 1.1.1 193============= 194 195This is a new-features and bug-fix release. 196 197- Support for setting PETSC_COMM_WORLD before PETSc initialization. 198 199- Support for coordinates, refinement and interpolation in DA. Many 200 thanks to Blaise Bourdin. 201 202- Workaround build failures when PETSc is built with *mpiuni*. 203 204- Workaround GIL-related APIs for non-threaded Python builds. 205 206 207Release 1.1 208=========== 209 210- Update for API cleanups, changes, and new calls in PETSc 3.1 and 211 some other missing features. 212 213- Add support for Jed Brown's THETA an GL timestepper implementations. 214 215- Fix the annoying issues related to Open MPI shared libraries 216 dependencies and Python dynamic loading. 217 218- Many minor bug-fixes. Many thanks to Ethan Coon, Dmitry Karpeev, 219 Juha Jaykka, and Michele De Stefano. 220 221 222Release 1.0.3 223============= 224 225This is a bug-fix release. 226 227- Added a quick fix to solve build issues. The macro __SDIR__ is no 228 longer passed to the compiler in the command line. 229 230 231Release 1.0.2 232============= 233 234This is a new-features and bug-fix release. 235 236- Now ``petsc4py`` works against core PETSc built with complex 237 scalars. 238 239- Added support for PETSc logging features like stages, classes and 240 events. Stages and events support the context manager interface 241 (``with`` statement). 242 243- Documentation generated with Epydoc and Sphinx is now included in 244 the release tarball. 245 246- Removed enumeration-like classes from the ``petsc4py.PETSc`` module 247 namespace. For example, now you have to use ``PETSc.KSP.Type`` 248 instead of ``PETSc.KSPType``. 249 250- The ``PETSc.IS`` to ``numpy.ndarray`` conversion now works for 251 stride and block index sets. 252 253- Implemented a more robust import machinery for multi-arch 254 ``petsc4py`` installations. Now a wrong value in the ``PETSC_ARCH`` 255 environmental variable emit a warning (instead of failing) at import 256 time. 257 258- The unittest-based testsuite now can run under ``nose`` with its 259 default options. 260 261- Removed the dependency on ``numpy.distutils``, just use core Python 262 ``distutils``. 263 264 265Release 1.0.1 266============= 267 268This is a bug-fix release. Compile Cython-generated C sources with 269``-Wwrite-strings`` removed, as this flag (inherited from PETSc) made 270GCC emit a lot of (harmless but annoying) warnings about conversion of 271string literals to non-const char pointers. 272 273 274Release 1.0.0 275============= 276 277This is the fist release of the all-new, Cython-based, implementation 278of *PETSc for Python*. 279
