PyPy 5.3.1

We have released a bugfix for PyPy2.7-v5.3.0, released last week, due to issues reported by users.

Thanks to those who reported the issues.

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.

We also welcome developers of other dynamic languages to see what RPython can do for them.

This release supports:

  • x86 machines on most common operating systems (Linux 32/64, Mac OS X 64, Windows 32, OpenBSD, FreeBSD),

  • newer ARM hardware (ARMv6 or ARMv7, with VFPv3) running Linux,

  • big- and little-endian variants of PPC64 running Linux,

  • s390x running Linux

Please update, and continue to help us make PyPy better.

Cheers

The PyPy Team
