Python 3.9.7 is the newest major stable release of
the Python programming language, and it contains many new features and
optimizations. There’s been 187 commits since 3.9.6 which is a similar
amount compared to 3.8 at the same stage of the release cycle. See the change log for details.
On macOS, we encourage you to use the universal2 binary installer variant whenever possible. The legacy 10.9+ Intel-only variant will not be provided for Python 3.10 and the universal2 variant will become the default download for 3.9.8. You may need to upgrade third-party components, like pip,
to later versions. You may experience differences in behavior in IDLE
and other Tk-based applications due to using the newer version of Tk.
As always, if you encounter problems when using this installer variant,
please check https://bugs.python.org for existing reports and for opening new issues.
The next Python 3.9 maintenance release will be 3.9.8, currently scheduled for 2021-11-01.
Security content in this release contains four fixes. There are also
four additional fixes for bugs that might have lead to denial-of-service
attacks. Finally, while we’re not providing binary installers anymore,
for those users who produce installers, we upgraded the OpenSSL version
used to 1.1.1l. Take a look at the change log for details.
According to the release calendar specified in PEP 569,
Python 3.8 is now in “security fixes only” stage of its life cycle: 3.8
branch only accepts security fixes and releases of those are made
irregularly in source-only form until October 2024. Python 3.8 isn’t
receiving regular bug fixes anymore, and binary installers are no longer
provided for it. Python 3.8.10 was the last full bugfix release of Python 3.8 with binary installers.
Those aren’t ready just yet but are soon to follow.
Similarly to 3.8, Python 3.7 and 3.6 are now in “security fixes only”
stage of their life cycle. Python 3.7 will be providing source archives until June
2023 while Python 3.6 ends its life in December 2021.
