We have released PyPy 4.0.1, a bux-fix release after PyPy 4.0.1. We have fixed a few critical bugs in the JIT compiled code, reported by users. We encourage all users of PyPy to update to this version.
You can download the PyPy 4.0.1 release here:
We would like to thank our donors for the continued support of the PyPy project.
We would also like to thank our contributors and encourage new people to join the project. PyPy has many layers and we need help with all of them: PyPy and RPython documentation improvements, tweaking popular modules to run on pypy, or general help with making RPython’s JIT even better.
While not applicable only to PyPy, cffi is arguably our most significant contribution to the python ecosystem. PyPy 4.0.1 ships with cffi-1.3.1 with the improvements it brings.
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), as well as newer ARM hardware (ARMv6 or ARMv7, with VFPv3) running Linux.
We also introduce support for the 64 bit PowerPC hardware, specifically Linux running the big- and little-endian variants of ppc64.
Please update, and continue to help us make PyPy better.
Cheers
The PyPy Team
