Groovy 1.5 Released!

The Groovy team has kicked out their second major production release, Groovy 1.5...and skipped straight from 1.0 to 1.5. Why? Perhaps because they added generics, enums, static imports, annotations, fully dynamic metaclasses, improved performance, ... and much more. I think the move to 1.5 was certainly warranted, and we've been considering making the next JRuby release 1.5 for the same reasons.

Congratulations to the Groovy team! I'm looking forward to seeing 1.6 and 2.0 in the future!

OpenJDK Migration to Mercurial is Complete!

I'm really excited about this one. Kelly O'Hair reports that OpenJDK source has been fully migrated to Mercurial! This means that daily development on OpenJDK (eventually to produce Java 7 and other great things) will happen on the same repository that you, dear reader, can access from home. And it's using Mercurial, one of the two big Distributed SCM apps, so you can pull off an entire repo and maintain your own OpenJDK workshop at home. Excellent news...I now finally have an excuse to learn Hg, and I can finally put in the effort to get OpenJDK building with the knowledge that I'll safely be able to "pull" changes as they happen. Thank you to the OpenJDK migration team!
