PyPy3.3 v5.2 alpha 1 released

We're pleased to announce the first alpha release of PyPy3.3 v5.2. This is the
first release of PyPy which targets Python 3.3 (3.3.5) compatibility.

We would like to thank all of the people who donated to the py3k proposal
for supporting the work that went into this and future releases.

You can download the PyPy3.3 v5.2 alpha 1 release here:

Highlights

• Python 3.3.5 support!
  • Being an early alpha release, there are some missing features such as a
    PEP 393-like space efficient string representation and known issues
    including performance issues (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 one day 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!

We'd especially like to thank these people for their contributions to this
release:

Manuel Jacob, Ronan Lamy, Mark Young, Amaury Forgeot d'Arc, Philip Jenvey,
Martin Matusiak, Vasily Kuznetsov, Matti Picus, Armin Rigo and many others.

Cheers

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.

Cheers
