============================
PyPy 2.1 - Considered ARMful
============================

We're pleased to announce PyPy 2.1, which targets version 2.7.3 of the
Python
language. This is the first release with official support for ARM
processors in the JIT.
This release also contains several bugfixes and performance improvements. 

You can download the PyPy 2.1 release here:

    http://pypy.org/download.html

We would like to thank the Raspberry Pi Foundation http://www.raspberrypi.org for
supporting the work
to finish PyPy's ARM support.


The first beta of PyPy3 2.1, targeting version 3 of the Python language,
was
just released, more details can be found here: http://morepypy.blogspot.com/2013/07/pypy3-21-beta-1.html


What is PyPy?
=============

PyPy is a very compliant Python interpreter, almost a drop-in replacement
for
CPython 2.7. It's fast (http://speed.pypy.org)
due to its integrated tracing JIT compiler.

This release supports x86 machines running Linux 32/64, Mac OS X 64 or
Windows
32. This release also supports ARM machines running Linux 32bit - anything
with
ARMv6 (like the Raspberry Pi) or ARMv7 (like the Beagleboard,
Chromebook, Cubieboard, etc.) that supports VFPv3 should work. Both
hard-float armhf/gnueabihf and soft-float armel/gnueabi builds are
provided. armhf builds for Raspbian are created using the Raspberry Pi
`custom cross-compilation toolchain <https://github.com/raspberrypi>`_
based on gcc-arm-linux-gnueabihf and should work on ARMv6 and
ARMv7 devices running Debian or Raspbian. armel builds are built
using the gcc-arm-linux-gnuebi toolchain provided by Ubuntu and
currently target ARMv7.

Windows 64 work is still stalling, we would welcome a volunteer
to handle that.


Highlights
==========

* JIT support for ARM, architecture versions 6 and 7, hard- and soft-float
ABI

* Stacklet support for ARM

* Support for os.statvfs and os.fstatvfs on unix systems

* Subarrays for numpy

* Bugfixes to numpy

* Bugfixes to cffi and ctypes

* Bugfixes to the x86 stacklet support

* Fixed issue 1533: fix an RPython-level OverflowError for
space.float_w(w_big_long_number). https://bugs.pypy.org/issue1533

* Fixed issue 1552: GreenletExit should inherit from BaseException. https://bugs.pypy.org/issue1552

* Fixed issue 1537: numpypy __array_interface__ https://bugs.pypy.org/issue1537
  
* Fixed issue 1238: Writing to an SSL socket in PyPy sometimes failed with
a "bad write retry" message. https://bugs.pypy.org/issue1238

Cheers,

David Schneider for the PyPy team.
