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:

The Groovy team is happy to announce its intention to join the Apache Software Foundation (ASF).

Following up the recent announcement from Pivotal to end funding of full time developers for the Groovy programming language project, the team thought it would be appropriate to demonstrate to the Groovy community that the project is here for the long term, regardless of any funding from particular sponsoring organizations and regardless of any changes to the team of committers over time.

This round number edition is pretty busy!

Last week ended with a pretty sad note, with the news of Leonard Nimoy’s passing, the famous vulcan extraterrestrial from Star Trek. This certainly resonates with the Groovy community (and geeks & fans out large) because of our very own Spock testing framework. So let’s all gather and have a thought for this great actor and for his family.

But as a tribute to this great actor and character, the long awaited news is that the Spock testing framework releases its 1.0 version!

Groovy keeps rocking with a joint release of Groovy 2.4.1 and also a 2.3.10!

And did you notice the nice new design of the new Grails website, based on Groovy’s website? That’s a family look!

Also, I’d like to end this short editorial with a big congrats to the GVM team who’s reached the 100,000 unique installs! That’s a big milestone!

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.

The past week’s been pretty calm, in terms of news, but a few of them really stood out.

Netflix again leverages Groovy for scripting its user experience API (additional coverage following last week’s announcement).

The Gradleware team delivered Gradle 2.3! Congrats guys!

And closer to home, a very important discussion about moving Groovy into a foundation has started, inviting members and representatives of different foundations to join and offer their views and experience on the matter.

So what’s Groovy this week? The Groovy community is still celebrating the 4.5+ million downloads of Groovy last year, is drive testing the upcoming Gradle 2.3, while Greach is announcing its impressive roster of speakers.

But there’s an item of news dear to my heart this week, with the “go to production” message from Dierk about Groovy in Action, second edition! Many times the book has been revised to catch up with the latest and greatest of Groovy, and this new edition will bring you up-to-date with Groovy 2.4, so you can expect the official print and e-book final versions imminently!

Congrats to the GrooScript team with the GrooScript 1.0 release! With GrooScript, if you will, you can have a full Groovy experience, from the build (Gradle), backend (Groovy, Grails, Ratpack), mobile (Groovy on Android), up to the front-end web layer with Groovy translated into JavaScript!

Another impressive and widely acclaimed release is the first milestone of Grails 3! You can have a look at the novelties in Grails 3, and watch a screencast about it.
