Python 3.9.13 is now available

This is the thirteenth maintenance release of Python 3.9. Get it here:
Python 3.9.13 <https://www.python.org/downloads/release/python-3913/>
According to the release calendar specified in PEP 596 <https://www.python.org/dev/peps/pep-0596/>, Python 3.9.13 is the final regular maintenance release. Starting now, the 3.9 branch will only accept security fixes and releases of those will be made in source-only form until October 2025.

This is a milestone moment for me as it means that now both of my release series are security-only. My work as release manager enters its final stage. I’m not crying, you’re crying! 

Compared to the 3.8 series, this last regular bugfix release is still pretty active at 166 commits since 3.9.12. In comparison, version 3.8.10, the final regular bugfix release of Python 3.8, included only 92 commits. However, it’s likely that it was 3.8 that was special here with the governance changes occupying core developers’ minds. For reference, version 3.7.8, the final regular bugfix release of Python 3.7, included 187 commits.

In any case, 166 commits is quite a few changes, some of which being pretty important fixes. Take a look at the change log <https://docs.python.org/release/3.9.13/whatsnew/changelog.html> for details.
