PyPy 2.0.1 - Bohr Smørrebrød
==============================
We're pleased to announce PyPy 2.0.1. This is a stable bugfix release
over `2.0`_. You can download it here:
http://pypy.org/download.html
The fixes are mainly about fatal errors or crashes in our stdlib. See
below for more details.
What is PyPy?
=============
PyPy is a very compliant Python interpreter, almost a drop-in replacement for
CPython 2.7. It's fast (`pypy 2.0 and cpython 2.7.3`_ performance comparison)
due to its integrated tracing JIT compiler.
This release supports x86 machines running Linux 32/64, Mac OS X 64 or
Windows 32. Support for ARM is progressing but not bug-free yet.
.. _`pypy 2.0 and cpython 2.7.3`: http://speed.pypy.org
Highlights
==========
- fix an occasional crash in the JIT that ends in `RPython Fatal error:
NotImplementedError`__.
- `id(x)` is now always a positive number (except on int/float/long/complex).
This fixes an issue in ``_sqlite.py`` (mostly for 32-bit Linux).
- fix crashes of callback-from-C-functions (with cffi) when used together
with Stackless features, on asmgcc (i.e. Linux only). Now `gevent should
work better`__.
- work around an eventlet issue with `socket._decref_socketios()`__.
