# PyPy 5.0.1

We have released a bugfix for PyPy 5.0, after reports that the newly released lxml 3.6.0, which now supports PyPy 5.0 +, can crash on large files. Thanks to those who reported the crash. Please update, downloads are available at pypy.org/download.html

The changes between PyPy 5.0 and 5.0.1 are only two bug fixes: one in cpyext, which fixes notably (but not only) lxml; and another for a corner case of the JIT.

## 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, and the big- and little-endian variants of PPC64 running Linux.

Please update, and continue to help us make PyPy better.

Cheers

The PyPy Team
