PyPy v7.3.10 release

PyPy v7.3.10: release of python 2.7, 3.8, and 3.9¶

The PyPy team is proud to release version 7.3.10 of PyPy. We have some nice speedups and bugfixes we wish to share. 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)

• PyPy3.8, which is an interpreter supporting the syntax and the features of Python 3.8, including the stdlib for CPython 3.8.15.

• PyPy3.9, which is an interpreter supporting the syntax and the features of Python 3.9, including the stdlib for CPython 3.9.15. We have gained confidence in the stability of this version, and are removing the "beta" label.

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. Highlights of the release, since the release of 7.3.9 in March 2022 include:

• A release of Apple Silicon M1 arm64 versions. This work was sponsored by an anonymous donor and is tested on our buildbots.

• Many improvements to the basic interpreter to make it 15-20% faster

• The conda-forge community has built over 1000 packages for PyPy3.8 and 3.9, making it easier than ever to use PyPy.

• Update the packaged OpenSSL to 1.1.1s, sqlite3 to 3.39.4, and apply applicable security fixes from CPython 3.9.15 to PyPy2.7

• Update the HPy backend in PyPy3.8 and PyPy3.9 to 0.0.4

We recommend updating. You can find links to download the v7.3.10 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 five new contributors, 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.
