Python buildpacks updated to uv 0.9.7
Change effective on 03 November 2025
We have updated the package managers used during the build of Python apps as follows:
- uv updated from 0.9.5 to 0.9.7 (changelog)
If you have not used the package manager uv before, we highly recommend giving it a try - it supports lockfiles, is extremely fast, and is actively maintained by a full-time team! Learn more in our blog post Heroku Adds Support for uv.
