The Groovy development team is happy to announce the bug fix releases of Groovy 2.4.2 and Groovy 2.3.11.

For the 2.4.2 release, some **key performance improvements have found their way in static compilation mode**, so you might be happy to see your programs snappier!

Along with those two releases, you'll notice **lots more documentation has been written** on the new Groovy website, as well as important updates to existing topics. You might want to have a look at the following new or improved sections:

Note that it might be the last releases under the Codehaus era, as Groovy is **currently being voted for incubation at the Apache Software Foundation**. The vote is ongoing right now, as I write those lines, so we should know pretty soon what's the outcome, and if Groovy is accepted or not! So far... only positive votes!

You can:

*   **download** those latest Groovy releases in our [download area](http://www.groovy-lang.org/download.html)
*   read the **release notes** for
*   [Groovy 2.4.2](http://www.groovy-lang.org/changelogs/changelog-2.4.2.html)
*   [Groovy 2.3.11](http://www.groovy-lang.org/changelogs/changelog-2.3.11.html)

Thanks a lot to all who contributed to those releases, and thanks for your support of Groovy and your positive feedback on our move to Apache!

Keep on groovy'ing!
