PyPy 2.3.1 - Terrestrial Arthropod Trap Revisited

We're pleased to announce PyPy 2.3.1, a feature-and-bugfix improvement over our recent 2.3 release last month.

This release contains several bugfixes and enhancements among the user-facing improvements:
  • The built-in struct module was renamed to _struct, solving issues with IDLE and other modules
  • Support for compilation with gcc-4.9
  • A CFFI-based version of the gdbm module is now included in our binary bundle
  • Many issues were resolved since the 2.3 release on May 8

You can download the PyPy 2.3.1 release here:

PyPy is a very compliant Python interpreter, almost a drop-in replacement for CPython 2.7. It's fast (pypy 2.3.1 and cpython 2.7.x performance comparison) due to its integrated tracing JIT compiler.

This release supports x86 machines running Linux 32/64, Mac OS X 64, Windows, and OpenBSD, as well as newer ARM hardware (ARMv6 or ARMv7, with VFPv3) running Linux. 
We would like to thank our donors for the continued support of the PyPy project.

The complete release notice is here.

Please try it out and let us know what you think. We especially welcome success stories, please tell us about how it has helped you!

Cheers, The PyPy Team
