 ## [Unreleased]

+## [6.9.0] - 2022-07-28
 ### Added
 * Clang and Black no longer break the build when the binary is unavailable, if they will not be run during that build ([#1257](https://github.com/diffplug/spotless/pull/1257)).
 * License header support for Kotlin files without `package` or `@file` but do at least have `import` ([#1263](https://github.com/diffplug/spotless/pull/1263)).
