This is a stable release that brings +swath of bugfixes, small performance improvements and compatibility fixes. + +You can download the PyPy 2.0 release here: + + http://pypy.org/download.html + +Two biggest changes since PyPy 1.9 are: + +* stackless is now supported including greenlets, which means eventlet + and gevent should work (but read below about gevent) + +* PyPy now contains a release 0.6 of `cffi`_ as a builtin module, which + is preferred way of calling C from Python that works well on PyPy + +.. _`cffi`: http://cffi.readthedocs.org + +What is PyPy? +============= + +PyPy is a very compliant Python interpreter, almost a drop-in replacement for +CPython 2.7.
