Change effective on 04 December 2024

Python 3.13.1, 3.12.8, 3.11.11, 3.10.16 and 3.9.21 are now available for use on Heroku.

In addition, the Python 3.13, 3.12, 3.11, 3.10 and 3.9 major version aliases have been updated to resolve to those new Python patch versions. If your app uses one of those major version aliases (recommended) it will automatically pick up the latest Python patch release the next time you build it.

See Specifying a Python Version for details on how to configure the Python version for your app.
