Groovy Weekly #36

The SpringOne2GX 2014 conference is over, but you can see below more tweets and presentations from the second part of the conference, and the videos will be available later on on InfoQ.


Apart from the excitement around Grails 3, Spring Boot, Groovy, and more, I’d like to highlight the very interesting feedback from Scott Hickey who comes back on 6 years of production usage of Groovy at Mutual of Omaha, saying “Groovy is a phenomenal language for businnes applications”, and that there’s nothing “better” on the JVM! See the first couple of tweets in the Twitter section.

Groovy Weekly #34 back from vacations!

After a long summer break, it’s high time we resume Groovy Weekly, and come back to our every-Tuesday agenda! Get ready for lots of content!


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”.


Speaking of Groovy 2.4, it’s interesting to note that the new beta released today reduces the bytecode size, by not generating unneeded methods anymore. This should make Android developers happy, since they are overal limited in the number of methods in Android applications.


Next week will be pretty Groovy in Dallas, as the SpringOne2GX conference will be on. Perhaps we won’t have yet much news and presentations to share next Tuesday, but the following week will list all the great content and news happening at the conference. If you’re around, don’t hesitate to tell hi!

Beta 3 for Groovy 2.4

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

You can read the JIRA release notes and go straight to the download area!
