According to the release calendar specified in PEP 537, Python 3.7 is now in the "security fixes only" stage of its life cycle: 3.7 branch only accepts security fixes and releases of those are made irregularly in source-only form until June 2023. Python 3.7 does not receive regular bug fixes anymore, and binary installers are no longer provided for it. Python 3.7.9 was the last full bugfix release of Python 3.7 with binary installers.
