+==== Reduce spock-core direct groovy dependencies
+
+`spock-core` now only depends on `groovy.jar`. All other Groovy dependencies have been removed,
+this should make dependency management a bit easier.
+If you relied on other groovy dependencies transitively, you will need to add them directly.

 ==== Upgrade to JUnit 5.6 (and JUnit Platform 1.6)
 
 JUnit Platform 1.6 (https://junit.org/junit5/docs/5.6.0/release-notes/index.html#deprecations-and-breaking-changes[deprecated]) methods (from experimental API)  in `EngineExecutionResults` that Spock was using. To keep runtime compatibility with JUnit 5.6 and incoming 5.7 the implementation has been switched to the new methods. As a result, Spock 2.0-M3 cannot work with JUnit 5.5 and lower. The problem might only occur if a project overrides default JUnit Platform version provided by Spock.
