Support for Python 3.9, 3.10, 3.11

I noticed that it is not under active development and has not been updating in a while.
Is there a plan for an update?

Is there something that's explicitly broken? As far as I'm aware, it works great with 3.9, 3.10 and 3.11.

And the last release was done in February 2022, it's mostly feature complete for a few years now, so "not under active development" is missing the point.

Closing as "works for me". Please reopen if there's an actual issue with newer versions and be more specific, then we can fix any real issues. Thanks!
