PyPy3 v5.5.0¶
We’re pleased to announce the release of PyPy3 v5.5.0. Coming four months after PyPy3.3 v5.2, it improves compatibility with Python 3.3 (3.3.5). We strongly recommend updating from previous PyPy3 versions.
We would like to thank all of the people who donated to the py3k proposal for supporting the work that went into this release.
You can download the PyPy3.3 v5.5.0 release here:
Highlights¶
Improved Python 3.3.5 support.
os.get_terminal_size(), time.monotonic(), str.casefold()
faulthandler module
There are still some missing features such as a PEP 393-like space efficient string representation and known issues including performance regressions (e.g. issue #2305). The focus for this release has been updating to 3.3 compatibility. Windows is also not yet supported.
ensurepip is also included (it’s only included in CPython 3 >= 3.4).
What is PyPy?¶
PyPy is a very compliant Python interpreter, almost a drop-in replacement for CPython 2.7.10 and 3.3.5. It’s fast 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 except Windows (Linux 32/64, Mac OS X 64, 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 try it out and let us know what you think. We welcome feedback, we know you are using PyPy, please tell us about it!
Cheers
