 * Allow to specify node executable for node-based formatters using `nodeExecutable` parameter ([#1500](https://github.com/diffplug/spotless/pull/1500))
 ### Fixed
 * The default list of type annotations used by `formatAnnotations` has had 8 more annotations from the Checker Framework added [#1494](https://github.com/diffplug/spotless/pull/1494)
