PyPy v7.3.9 security release

PyPy v7.3.9 security release

The PyPy team is proud to release version 7.3.9 of PyPy. This is a security release to match the recent CPython release and updates the portable pypy tarballs with bzip2 1.0.8, openssl1.1.1n, and libexpat 2.4.7. Along the way this release fixes some issues discovered after the 7.3.8 release and updates sqlite3 to 3.38.2. It includes:

• 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)

• PyPy3.7, which is an interpreter supporting the syntax and the features of Python 3.7, including the stdlib for CPython 3.7.13. This will be the last release of PyPy3.7.

• PyPy3.8, which is an interpreter supporting the syntax and the features of Python 3.8, including the stdlib for CPython 3.8.13.

• PyPy3.9, which is an interpreter supporting the syntax and the features of Python 3.9, including the stdlib for CPython 3.9.12. We relate to this as "beta" quality. We welcome testing of this version, if you discover incompatibilities, please report them so we can gain confidence in the version.

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 7.3.8 in February 2022, include:

• Fixed some failing stdlib tests on PyPy3.9

• Update the bundled libexpat to 2.4.6 and sqlite3 to 3.38.2

We recommend updating. You can find links to download the v7.3.9 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: PyPy and RPython documentation improvements, tweaking popular modules to run on PyPy, or general help with making RPython's JIT even better. Since the 7.3.7 release, we have accepted contributions from 6 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.
