Release Notes

diffplug/spotless (com.diffplug.spotless:spotless-maven-plugin)

### [`v2.40.0`](https://togithub.com/diffplug/spotless/blob/HEAD/CHANGES.md#2400---2023-07-17) ##### Added - Added support for Protobuf formatting based on [Buf](https://buf.build/). ([#​1208](https://togithub.com/diffplug/spotless/issues/1208)) - `enum OnMatch { INCLUDE, EXCLUDE }` so that `FormatterStep.filterByContent` can not only include based on the pattern but also exclude. ([#​1749](https://togithub.com/diffplug/spotless/pull/1749)) ##### Fixed - Update documented default `semanticSort` to `false`. ([#​1728](https://togithub.com/diffplug/spotless/pull/1728)) ##### Changes - Bump default `cleanthat` version to latest `2.13` -> `2.17`. ([#​1734](https://togithub.com/diffplug/spotless/pull/1734)) - Bump default `ktlint` version to latest `0.49.1` -> `0.50.0`. ([#​1741](https://togithub.com/diffplug/spotless/issues/1741)) - Dropped support for `ktlint 0.47.x` following our policy of supporting two breaking changes at a time. - Dropped support for deprecated `useExperimental` parameter in favor of the `ktlint_experimental` property.
