The first release of the Python buildpack after 2020-10-14 will no longer include Python versions 3.5.x. These Python versions will no longer be supported upstream. Please migrate your Python apps to supported versions of Python before that time.
Note: If you’d like to use a different Python version, please configure your application to select that version.
As always, the buildpacks team is happy to answer questions you may have about this deprecation in the #buildpacks Slack channel.
