Latest news [more]
The Groovy development team is happy to announce the joint releases of the Groovy 2.4.1 and Groovy 2.3.10 of the Groovy programming language for the Java platform.
Both releases are bug fix releases, and while Groovy 2.4.1 is the latest official stable branch, we thought it might be helpful to some projects who are still on the 2.3.x line to get a final release for that branch. But going forward, the 2.3.x branch won’t see any upcoming release.

For reference, you can also read the release notes of Groovy 2.4 if you haven't had a chance to since the announcement.

Thanks a lot for all those who contributed to this release!
