The only linter message that came up due to this change was use_super_parameters. I applied the "quick fix" for each message, so now there are no longer any issues.

Pull request type

Please check the type of change your PR introduces:

• Code style update (formatting, renaming)
• Refactoring (no functional changes, no api changes)
• Build related changes
• Documentation content changes
• Other (please describe): dependency change

Summary of changes

This change removes the version restriction for the lints dependency.

# before
  lints: ">=1.0.1 <2.1.2"

# after
  lints: ">=1.0.1"

Once this change is implemented, developers who use this plugin won't be prevented from using new linting features.

Does this introduce a breaking change?

• Yes
• No

The lints package is just for static analysis, so there shouldn't be any impact on functionality.

[nate-thegrate]

I just realized that this PR is almost identical to another pull request that has already been opened.

However, the other PR is set to ^3.0.0 instead of ">=1.0.1", which may cause version conflicts.

Looks good!
