We're pleased to announce PyPy 2.0.1. This is a stable bugfix release over 2.0. You can download it here:
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.
- 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().
Cheers, arigo et. al. for the PyPy team
