Python buildpacks updated to pip 25.1.1, Poetry 2.1.3 and uv 0.7.6

Change effective on 20 May 2025

We have updated the package managers used during the build of Python apps as follows:

  • pip updated from from 25.0.1 to 25.1.1 (changelog)
  • Poetry updated from 2.1.2 to 2.1.3 (changelog)
  • uv updated from from 0.7.3 to 0.7.6 (changelog)

We recently added support for uv. 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 here.
