PyPy 5.1.1 bugfix released

We have released a bugfix for PyPy 5.1, due to a regression in installing third-party packages depending on numpy (using our numpy fork available at https://bitbucket.org/pypy/numpy ).

Thanks to those who reported the issue. We also fixed a regression in translating PyPy which increased the memory required to translate. Improvement will be noticed by downstream packagers and those who translate rather than
download pre-built binaries.

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.
