BreakingUpgrade verdict

6 breaking changes and a platform requirement change.

In plain terms
  • If you enable rules by prefix, deprecated rules will no longer be turned on that way.
  • On macOS, Ruff no longer reads a user config file from the old Application Support location; use the XDG path instead.
  • The PD901 lint rule is gone, so enabling it will no longer work.
  • The UP038 lint rule is gone, so enabling it will no longer work.
