PyPy 5.7.1 bugfix released

We have released a bugfix PyPy2.7-v5.7.1 and PyPy3.5-v5.7.1 beta (Linux 64bit), due to the following issues:
  • correctly handle an edge case in dict.pop (issue 2508)
  • fix a regression to correctly handle multiple inheritance in a C-API type where the second base is an app-level class with a __new__ function
  • fix a regression to fill a C-API type’s tp_getattr slot from a __getattr__ method (issue 2523)
Thanks to those who reported issues and helped test out the fixes

You can download the v5.7.1 release here:

What is PyPy?

PyPy is a very compliant Python interpreter, almost a drop-in replacement for CPython 2.7 and CPython 3.5. 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.
The PyPy 2.7 release supports:
  • x86 machines on most common operating systems (Linux 32/64 bits, Mac OS X 64 bits, Windows 32 bits, 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
