========== PyPy 5.7.1 ========== 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 the issues. .. _2508: https://bitbucket.org/pypy/pypy/issues/2508 .. _2523: https://bitbucket.org/pypy/pypy/issues/2523 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 .. _`PyPy and CPython 2.7.x`: https://speed.pypy.org .. _`dynamic languages`: https://rpython.readthedocs.io/en/latest/examples.html Please update, and continue to help us make PyPy better. Cheers The PyPy Team
