PyPy, the self-hosting alternative Python interpreter, is up to version 5.9 for its Python 2 and Python 3 language support.

PyPy 5.9 brings support for Numpy and Pandas with its Python 2.7 implementation, greater compatibility in conjunction with Cython 0.27.1, an optimized JSON parser, updated CFFI, improvements to the C API compatibility layer, and other updates.

The improvements to PyPy's JSON parser should drop memory use by half while increasing the parsing speed by up to 15% for larger JSON data files.

More details on PyPy 5.9 via the release announcement issued earlier today.
