 ## Unreleased
 
+- Python 3.9.13 is now available ([#1326](https://github.com/heroku/heroku-buildpack-python/pull/1326)).
 - Use shared builds + LTO when building Python 3.10 binaries ([#1320](https://github.com/heroku/heroku-buildpack-python/pull/1320)).
   Note: This and the other Python binary changes below will only take effect for future Python
   version releases (or future Heroku stacks) - existing Python binaries are not being recompiled.
