- Fixed issue 1552: GreenletExit should inherit from BaseException.
- Fixed issue 1537: numpypy __array_interface__
- Fixed issue 1238: Writing to an SSL socket in pypy sometimes failed with a “bad write retry” message.

- During packaging, compile the CFFI tk extension.

## What is PyPy?

PyPy is a very compliant Python interpreter, almost a drop-in replacement for CPython 2.7.3. It’s fast due to its integrated tracing JIT compiler.

This release supports x86 machines running Linux 32/64, Mac OS X 64 or Windows 32. Also this release supports ARM machines running Linux 32bit - anything with `ARMv6` (like the Raspberry Pi) or `ARMv7` (like Beagleboard, Chromebook, Cubieboard, etc.) that supports `VFPv3` should work.

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

## How to use PyPy?

We suggest using PyPy from a virtualenv. Once you have a virtualenv installed, you can follow instructions from pypy documentation on how to proceed. This document also covers other installation schemes.

Cheers, The PyPy Team.
