Source Facts

Python released 3.10.22, 3.11.17, 3.12.15, 3.13.16 and 3.14.8 on 1 October. The announcement states that Python 3.10 has reached the end of its five-year support period, with 3.10.22 its final release. Users still on that series should plan an upgrade to a supported version.

The announcement also distinguishes release formats: 3.10.22, 3.11.17 and 3.12.15 are source-only security releases. Version 3.13.16 is the last full maintenance release of 3.13, with only security fixes afterwards. Installer availability cannot be inferred from version numbers alone.

Next Steps for Businesses / Editorial Observations

Treat Python as a dependency of business tools, not just software on developers' computers. Test scripts, packages and schedules before migrating the runtime.

Next steps you can take

  • Inventory Python versions used by schedules, automation, backup utilities and containers, identifying 3.10 dependencies.
  • Test script and package compatibility on a supported version, retain a rollback plan, then replace the production environment.
