heroku/buildpacks-python v1.0.0

on GitHub

heroku/python

Removed

• Removed support for the deprecated runtime.txt file. Python versions must now be specified using a .python-version file instead. (#352)
• Removed support for Ubuntu 20.04 (and thus Heroku-20 / heroku/builder:20). (#358)

Changed

• Improved the error messages shown when .python-version contains an invalid Python version or stray invisible characters (such as ASCII control codes). (#353 and #354)
• Improved the error messages shown if I/O errors occur. (#355 and #356)
