According to the release calendar specified in PEP 719, Python 3.13 is now in the "security fixes only" stage of its life cycle:
the 3.13 branch only accepts security fixes, and releases of those are made irregularly in source-only form until October 2028.
Python 3.13 isn't receiving regular bug fixes anymore, and binary installers are no longer provided for it.
Python 3.13.17 was the last bugfix release of Python 3.13 with binary installers.
