We're pleased to announce the 2.0 beta 2 release of PyPy. This is a major release of PyPy and we're getting very close to 2.0 final, however it includes quite a few new features that require further testing. Please test and report issues, so we can have a rock-solid 2.0 final. It also includes a performance regression of about 5% compared to 2.0 beta 1 that we hope to fix before 2.0 final. The ARM support is not working yet and we're working hard to make it happen before the 2.0 final. The new major features are:

What is PyPy?

PyPy is a very compliant Python interpreter, almost a drop-in replacement for CPython 2.7.3. It's fast (pypy 2.0 beta 2 and cpython 2.7.3 performance comparison) due to its integrated tracing JIT compiler.

This release supports x86 machines running Linux 32/64, Mac OS X 64 or Windows 32. It also supports ARM machines running Linux, however this is disabled for the beta 2 release. Windows 64 work is still stalling, we would welcome a volunteer to handle that.

How to use PyPy?

We suggest using PyPy from a virtualenv. Once you have a virtualenv installed, you can follow instructions from pypy documentation on how to proceed. This document also covers other installation schemes.
