The three sub-projects are: + +* `Py3k`_ (supporting Python 3.x): We have released a Python 3.2.5 compatible version + we call PyPy3 2.4.0, and are working toward a Python 3.3 compatible version + +* `STM`_ (software transactional memory): We have released a first working version, + and continue to try out new promising paths of achieving a fast multithreaded Python + +* `NumPy`_ which requires installation of our fork of upstream numpy, + available `on bitbucket`_ + +.. _`Py3k`: http://pypy.org/py3donate.html +.. _`STM`: http://pypy.org/tmdonate2.html +.. _`NumPy`: http://pypy.org/numpydonate.html +.. _`on bitbucket`: https://www.bitbucket.org/pypy/numpy + +We would also like to encourage new people to join the project. PyPy has many +layers and we need help with all of them: `PyPy`_ and `Rpython`_ documentation +improvements, tweaking popular `modules`_ to run on pypy, or general `help`_ with making +Rpython's JIT even better. + +.. _`PyPy`: http://doc.pypy.org +.. _`Rpython`: http://rpython.readthedocs.org +.. _`modules`: http://doc.pypy.org/en/latest/project-ideas.html#make-more-python-modules-pypy-friendly +.. _`help`: http://doc.pypy.org/en/latest/project-ideas.html + +What is PyPy? +============= + +PyPy is a very compliant Python interpreter, almost a drop-in replacement for +CPython 2.7. It's fast (`pypy and cpython 2.7.x`_ performance comparison) +due to its integrated tracing JIT compiler. + +This release supports **x86** machines on most common operating systems +(Linux 32/64, Mac OS X 64, Windows, and OpenBSD), +as well as newer **ARM** hardware (ARMv6 or ARMv7, with VFPv3) running Linux. + +While we support 32 bit python on Windows, work on the native Windows 64 +bit python is still stalling, we would welcome a volunteer +to `handle that`_. + +.. _`pypy and cpython 2.7.x`: http://speed.pypy.org +.. _`handle that`: http://doc.pypy.org/en/latest/windows.html#what-is-missing-for-a-full-64-bit-translation + +Highlights +========== + +* The past months have seen pypy mature and grow, as rpython becomes the goto + solution for writing fast dynamic language interpreters. Our separation of + Rpython and the python interpreter PyPy is now much clearer in the + `PyPy documentation`_ and we now have seperate `RPython documentation`_. + Tell us what still isn't clear, or even better help us improve the documentation. + +* We merged version 2.7.9 of python's stdlib + +* The garbage collector now ignores parts of the stack which did not change + since the last collection, another performance boost + +* errno and LastError are saved around cffi calls so things like pdb will not + overwrite it + +* We continue to asymtotically approach a score of 7 times faster than cpython + on our benchmark suite, we now rank 6.98 on latest runs + +* Issues reported with our previous release were resolved_ after reports from users on + our issue tracker at https://bitbucket.org/pypy/pypy/issues or on IRC at + #pypy. + +.. _`PyPy documentation`: http://doc.pypy.org +.. _`RPython documentation`: http://rpython.readthedocs.org +.. _resolved: http://doc.pypy.org/en/latest/whatsnew-2.5.1.html + +Please try it out and let us know what you think. We especially welcome +success stories, we know you are using PyPy, please tell us about it! + +Cheers + +The PyPy Team _______________________________________________ pypy-commit mailing list [email protected] https://mail.python.org/mailman/listinfo/pypy-commit
