Changelog 0.7.x

0.7.0

Check out the blog post for a migration guide and overview of the changes!

Breaking changes

The pytest rules PT001 and PT023 now default to omitting the decorator parentheses when there are no arguments (#12838, #13292). This was a change that we attempted to make in Ruff v0.6.0, but only partially made due to an error on our part. See the blog post for more details.
The useless-try-except rule (in our tryceratops category) has been recoded from TRY302 to TRY203 (#13502). This ensures Ruff's code is consistent with the same rule in the tryceratops linter.
The lint.allow-unused-imports setting has been removed (#13677). Use lint.pyflakes.allow-unused-imports instead.
