PyPy 5.4.1 bugfix released

We have released a bugfix for PyPy2.7-v5.4.0, released last week, due to the following issues:

  • Update list of contributors in documentation and LICENSE file, this was unfortunately left out of 5.4.0. My apologies to the new contributors
  • Allow tests run with -A to find even if it is a script not a dynamically loadable file
  • Bump sys.setrecursionlimit() when translating PyPy, for translating with CPython
  • Tweak a float comparison with 0 in backendopt.inline to avoid rounding errors
  • Fix for an issue for translating the sandbox
  • Fix for and issue where unicode.decode('utf8', 'custom_replace') messed up the last byte of a unicode string sometimes
  • Update built-in cffi to version 1.8.1
  • Explicitly detect that we found as-yet-unsupported OpenSSL 1.1, and crash translation with a message asking for help porting it
  • Fix a regression where a PyBytesObject was forced (converted to a RPython object) when not required, reported as issue #2395
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.
