PyPy v7.3.12 release

PyPy v7.3.12: release of python 2.7, 3.9, and 3.10.¶

The PyPy team is proud to release version 7.3.12 of PyPy. This release includes a new string-to-int algorithm (also appearing in CPython 3.12) that is faster than the older one; support for symlinks in Windows; and our first Python3.10 version.

The release includes three different interpreters:

• PyPy2.7, which is an interpreter supporting the syntax and the features of Python 2.7 including the stdlib for CPython 2.7.18+ (the + is for backported security updates)

• PyPy3.9, which is an interpreter supporting the syntax and the features of Python 3.9, including the stdlib for CPython 3.9.17.

• PyPy3.10, which is an interpreter supporting the syntax and the features of Python 3.10, including the stdlib for CPython 3.10.12. This is our first release of 3.10, but based on past experience we are quite confident in its compatibility with upstream. Of course, we recommend testing your code with this new version before putting it into production. Note it does require at least cython 0.29.35 or cython 3.0.0b3

The interpreters are based on much the same codebase, thus the multiple release. This is a micro release, all APIs are compatible with the other 7.3 releases. It follows after 7.3.11 release on Dec 29, 2022

We recommend updating. You can find links to download the v7.3.12 releases here:

We would like to thank our donors for the continued support of the PyPy project. If PyPy is not quite good enough for your needs, we are available for direct consulting work. If PyPy is helping you out, we would love to hear about it and encourage submissions to our blog via a pull request to https://github.com/pypy/pypy.org

We would also like to thank our contributors and encourage new people to join the project. PyPy has many layers and we need help with all of them: bug fixes, PyPy and RPython documentation improvements, or general help with making RPython's JIT even better. Since the previous release, we have accepted contributions from one new contributor, thanks for pitching in, and welcome to the project!

If you are a python library maintainer and use C-extensions, please consider making a HPy / CFFI / cppyy version of your library that would be performant on PyPy. In any case, both cibuildwheel and the multibuild system support building wheels for PyPy.
