 - Added: disable comments that are reported as errors for various reasons are now reported as standard lint errors rather than a separate class of errors that must be handled specially ([#4973](https://github.com/stylelint/stylelint/pull/4973)).
 - Added: configured pattern in `*-pattern` rules violation message ([#4975](https://github.com/stylelint/stylelint/pull/4975)).
+- Added: `comment-pattern` rule ([#4962](https://github.com/stylelint/stylelint/pull/4962)).
 - Deprecated: `StylelintStandaloneReturnValue.reportedDisables`, `.descriptionlessDisables`, `.needlessDisables`, and `.invalidScopeDisables`. `.reportedDisables` will always be empty and the other properties will always be undefined, since these errors now show up in `.results` instead ([#4973](https://github.com/stylelint/stylelint/pull/4973)).
