Groovy is ...
An agile dynamic language for the Java Platform with many features that are inspired by languages like Python, Ruby and Smalltalk, making them available to Java developers using a Java-like syntax.
Developing web applications , writing shell scripts easily, writing concise, meaningful, test cases using Groovy's JUnit integration, or prototyping and producing real industrial strength applications have never been so concise and groovy.
Groovy works cleanly with all existing Java objects and libraries and compiles straight to Java bytecode in either application development or scripting mode.

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.
You can learn more about all the tickets closed by reading:
For reference, you can also read the release notes of Groovy 2.4 if you haven't had a chance to since the announcement.
Head over to the download section of the new Groovy website to download the binary distribution, or update your dependencies accordingly with those new version numbers.
Thanks a lot for all those who contributed to this release!
The Groovy team is happy to announce the release of Groovy 2.4.0!
- traits can use the @SelfType annotation with static type checking enabled to restrict to what classes traits can be applied
- GDK methods improvements
- some refinements to existing AST transformations
- further Groovysh improvements as well.
