Hi all,

The Groovy team is very pleased to announce the first beta of the Groovy 2.3 release! 

Groovy 2.3.0-beta-1 is actually already a feature-complete beta, so the release cycle towards the final version will be very short. Furthermore, Grails 2.4 is looking forward to integrating it rapidly as well for its upcoming major release too! So you can expect a general availability version of Groovy in the coming weeks, as we’ll move directly in “release candidate” mode after this beta. But your feedback, as usual, will be very important for trying out this beta in your respective projects, to tell us about any problem you might encounter.

In this email, below, I’ll give you a few pointers regarding the scope of the release, but we’ll be fleshing out a more detailed release notes document in the coming days and weeks with more information.

Warning: this is a lengthy email, but you’ll get to see all the new stuff and improvements the Groovy team and contributors have been working on!

The key highlights of Groovy 2.3 are:

Along with some slightly reduced startup time, Groovysh has seen new improvements in its code-completion capabilities:


Groovy wouldn’t be what it is without your support, your bug reports and feature requests, your contributions and pull requests, so big thanks to all those who contributed to this release in a way or another, including the usual suspects of the core team (Jochen, Paul, Cédric and myself), but also André (documentation, GroovyAssert, Groovy Console), Andres (Config slurper, @Sortable with Paul), Tim, Pascal (ConfigSlurper), Johanes (@TailRecursive), Paolo (new NIO module), Thibault (groovysh), Rick and Andrey (for the JSON support), Jim (base script class), Damien (GroovyDoc / GDK styling), Kenneth and several others I’ve forgotten to mention!

And in honor of this first beta release of Groovy 2.3, Cédric even decided to put his birthday on the same day, so happy birthday Cédric, and great work on this release!

We’re looking forward to your feedback running this beta to its pace!

It’s important to make this 2.3 release rock solid!
