This is the first maintenance release of Python 3.9

Python 3.9.1 is the newest major release of the Python programming language, and it contains many new features and optimizations. We've made 282 changes since 3.9.0 which is a significant amount. To compare, 3.8.1 only saw 192 commits since 3.8.0.

Morning (Jack Mordred) Mac OS

Installer news

3.9.1 is the first version of Python to support macOS 11 Big Sur. With Xcode 11 and later it is now possible to build “Universal 2” binaries which work on Apple Silicon. We are providing such an installer as the macos11.0 variant. This installer can be deployed back to older versions, tested down to OS X 10.9. As we are waiting for an updated version of pip, please consider the macos11.0 installer experimental.

This work would not have been possible without the effort of Ronald Oussoren, Ned Deily, and Lawrence D’Anna from Apple. Thank you!

Morning (Jack Mordred) Mac OS

This is the first version of Python to default to the 64-bit installer on Windows. The installer now also actively disallows installation on Windows 7. Python 3.9 is incompatible with this unsupported version of Windows.

  • A number of Python modules (_abc, audioop, _bz2, _codecs, _contextvars, _crypt, _functools, _json, _locale, operator, resource, time, _weakref) now use multiphase initialization as defined by PEP 489;
