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.

This week is a bit more positive than the previous with the announcement of the release of Groovy 2.4!

But some interesting and thoughtful pieces have also been written about last week’s sad news about Pivotal divesting in Groovy and Grails.

In spite of this, SpringOne2GX 2015 has been announced with 4 Groovy and Grails tracks, in Washington DC, mid-September.

Last but not least, the second edition of Groovy in Action is going into production!

The Groovy team is happy to announce the release of Groovy 2.4.0!

The big highlight of this release is the Android support, which allows developers to write Android applications fully using Groovy, with much less boilerplate code than raw Java.

The team also focused on various improvements in terms of performance, smaller bytecode generation, or memory consumption.

Other interesting aspects worth noticing in this release are:

• 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.

Please have a look at the full release notes for Groovy 2.4 to know more about the new features and all the interesting tickets closed.

This week’s edition of Groovy Weekly is a bit peculiar, as the big news of the week is Pivotal’s announcement that it will stop funding the Groovy and Grails projects.

As a result those popular Open Source projects are now seeking a new home!

You can read Guillaume Laforge’s and Graeme Rocher’s announcements to hear a bit more about the story. And if your company is interested in further funding the projects, please don’t hesitate to get in touch!

Pivotal just announced it’s decision to stop sponsoring and funding the development of the popular Groovy and Grails Open Source projects. As a result, both Groovy and Grails are looking for new sponsors willing to further help develop the projects full steam!

The Groovy programming language has been around for a while for more than 11 years. During that time, it has nicely evolved from a side hobby project to the very mature and successful alternative language it is today, used by Fortune 500 companies throughout the world, in various projects and contexts.

The Groovy development team released the second release candidate of Groovy 2.4, please be sure to check your applications with this version and report any issue you may be finding, so that we can all ensure 2.4 is a rock-solid release.

Note the publication of MrHaki’s Gradle Goodness Notebook! If you’re using Gradle, this is worth the investment to have that resource handy for mastering your build automation.
