PyPy3 2.1 beta 1

We’re pleased to announce the first beta of the upcoming 2.1 release of PyPy3. This is the first release of PyPy which targets Python 3 (3.2.3) compatibility.

We would like to thank all of the people who donated to the py3k proposal for supporting the work that went into this and future releases.

You can download the PyPy3 2.1 beta 1 release here:


  • The first release of PyPy3: support for Python 3, targetting CPython 3.2.3!
    • There are some known issues including performance regressions (issues #1540 & #1541) slated to be resolved before the final release.

What is PyPy?

PyPy is a very compliant Python interpreter, almost a drop-in replacement for CPython 2.7.3 or 3.2.3. It’s fast due to its integrated tracing JIT compiler.

This release supports x86 machines running Linux 32/64, Mac OS X 64 or Windows 32. Also this release supports ARM machines running Linux 32bit - anything with ARMv6 (like the Raspberry Pi) or ARMv7 (like Beagleboard, Chromebook, Cubieboard, etc.) that supports VFPv3 should work.

Windows 64 work is still stalling and 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.

Cheers, the PyPy team
