The PyPy development team has been busy working and we’ve now packaged our latest improvements, completed work and new experiments as version 0.8.0, our third public release.
The highlights of this third release of PyPy are:
PyPy is a MIT-licensed research-oriented reimplementation of Python written in Python itself, flexible and easy to experiment with. It translates itself to lower level languages. Our goals are to target a large variety of platforms, small and large, by providing a compilation toolsuite that can produce custom Python versions. Platform, Memory and Threading models are to become aspects of the translation process - as opposed to encoding low level details into a language implementation itself. Eventually, dynamic optimization techniques - implemented as another translation aspect - should become robust against language changes.
Note that PyPy is mainly a research and development project and does not by itself focus on getting a production-ready Python implementation although we do hope and expect it to become a viable contender in that area sometime next year.
PyPy is partially funded as a research project under the European Union’s IST programme.

The interpreter and object model implementations shipped with the 0.8 version can run on their own and implement the core language features of Python as of CPython 2.4. However, we still do not recommend using PyPy for anything else than for education, playing or research purposes.
At the last sprint in Paris we started exploring the new directions of our work, in terms of extending and optimizing PyPy further. We started to scratch the surface of Just-In-Time compiler related work, which we still expect will be the major source of our future speed improvements and some successful amount of work has been done on the support needed for stackless-like features.
This release also includes the snapshots in preliminary or embryonic form of the following interesting but yet not completed sub projects:
PyPy has been developed during approximately 16 coding sprints across Europe and the US. It continues to be a very dynamically and incrementally evolving project with many of these one-week workshops to follow.
PyPy has been a community effort from the start and it would not have got that far without the coding and feedback support from numerous people. Please feel free to give feedback and raise questions.

PyPy development and activities happen as an open source project and with the support of a consortium partially funded by a two year European Union IST research grant. The full partners of that consortium are:
Heinrich-Heine University (Germany), AB Strakt (Sweden) merlinux GmbH (Germany), tismerysoft GmbH (Germany) Logilab Paris (France), DFKI GmbH (Germany) ChangeMaker (Sweden), Impara (Germany)
