The Groovy development team's just released Groovy 2.0.4, a bug fix for our Groovy 2.0 branch.
It fixes some important issues we've had with generics with the stub generator, as well as several fixes related to the static type checking and static compilation features. We also worked on the recompilation issues with the GroovyScriptEngine.
If you're curious why we've jumped from 2.0.2 to 2.0.4, skipping 2.0.3, it's because of some issues with the release of 2.0.3 which I had mistakenly built with JDK 6 instead of JDK 7, which ruled out all our invoke dynamic support. So we quickly moved to 2.0.4.
We'll certainly also release a 1.8.9 soon, especially for the stub generator fixes which might be useful for those affected with the issues we've fixed.
Keep on groovy'ing!
