The final version of Groovy 1.6 is there

This is with very great pleasure and honor that I’m announcing the final release of Groovy 1.6, on behalf of the Groovy development team and SpringSource.
Obviously, 1.6 is a very important milestone for the project, with several great new features and improvements:

  • great runtime performance improvements
  • multiple assignments
  • optional return in if/else and try/catch blocks
  • AST transformations and all the provided transformation annotations like @Singleton, @Lazy, @Immutable, @Delegate and friends
  • the Grape module and dependency system and its @Grab transformation
  • various Swing builder improvements, thanks to the Swing / Griffon (http://griffon.codehaus.org) team
  • as well as several Swing console improvements
  • the integration of JMX builder
  • JSR-223 scripting engine built-in
  • various metaprogramming improvements, like the EMC DSL, per-instance metaclasses even for POJOs, and runtime mixins

An article will be published in the coming days on InfoQ and GroovyMag coming back on all those features and novelties with more details.

You can download Groovy 1.6 at the usual place:http://groovy.codehaus.org/Download
Additional installers and bundles will be provided soon.

And you can also have a look at the JIRA changelog listing features, improvements and bug fixes.

Very big thanks to all the developers who contributed to the project, in particular our most prolific ones like Paul, Roshan, Danno and Jochen, and to all our users who’ve helped shape the project, thanks to their great feedback and suggestions.

Let me also mention an interesting event which is shaping up: the GR8 Conference, a conference dedicated to Groovy, Grails and Griffon, organized by the Danish JUG and SpringSource!

You can learn more about the event on the conference website: http://www.gr8conf.org or by following the twitter account: GR8 Conference Twitter account

The conference takes place in Copenhagen, Denmark, and will provideseveral practical sessions and hands-on labs to get you up-to-speed on those great Groovy-based technologies. The registration should be open in the coming days, so get ready!
