PyPy logo The PyPy developers have announced the release of version 1.2 of their Python runtime environment, PyPy. This is the first release to ship with a Just-In-Time (JIT) compiler, although the developers do note that it should be considered beta software as it only supports 32 bit x86 platforms and is still "memory-hungry". However the JIT is stable and the developers say it is "known to be faster than CPython (and Unladen Swallow) on some real world applications". The release incorporates a number of interpreter optimisations for better performance and leaner memory use.

The developers have announced a new website, a service that monitors PyPy's nightly performance and the future availability of Ubuntu packages in a PyPy PPA . Binaries of PyPy for Linux, Mac OS X and Windows can be obtained from the download page and the MIT licensed source code is also available.
