Preparing for Python 3.13

[dangotbanned]

https://www.python.org/downloads/release/python-3130rc2/

This release, 3.13.0rc2, is the final release preview. This release is expected to become the final 3.13.0 release, barring any critical bugs being discovered.
The official release of 3.13.0 is scheduled for Tuesday, 2024-10-01.

There will be no ABI changes from this point forward in the 3.13 series.
Call to action
We strongly encourage maintainers of Python projects to prepare their projects for 3.13 compatibilities during this phase, and where necessary publish Python 3.13 wheels on PyPI to be ready for the final release of 3.13.0.
Any binary wheels built against Python 3.13.0rc1 and later will work with future versions of Python 3.13. As always, report any issues to the Python bug tracker.
