The Groovy development team is happy to announce the release of a third beta for Groovy 2.4. This release contains various bug fixes and minor improvements. I’ll highlight the fact that you can now use multiple labels on your statements (instead of just one). With beta-3 now, many of the unneeded synthetic methods generated by Groovy are not generated anymore, reducing the number of methods nicely yielding smaller bytecode. This is of particular interest for Android developers limited in the overall number of methods used in Android applications. Read more...

If there were one particular item of news I’d like to highlight in this edition, that’s the news about the New York Times that is going to use Groovy and its Android support (in the upcoming Groovy 2.4), as well as RxJava, to revamp its Android application to make more “reactive”.

On the Groovy mailing-list, we had an interesting question about how to disable annotations like @Grab, to prevent users from downloading third-party dependencies. There are a few possibilities for that, but my favorite was to create a global AST transformation that would generate a compilation error if the @Grab annotation is found on an import.

You probably remember Groovy and Gradle being selected in RebelLabs’ report as part of the 10 “kick-ass” technologies developers love? But I’m also happy to report that Groovy won the Geek Choice Award, showing how groovy Groovy is!
