In this post I'll provide you update on recent changes that happened in NetBeans. These changes will be available in 6.8 M1.
The most important thing fixed in trunk (and in 6.5.1 as well) is a regression 161176 causing "unresolved class" problems when Groovy class was referenced in Java.
Other great improvement is much better code completion for variables and parameters. As picture is worth a thousand words, compare the following two pictures.

Variable code completion in trunk:
There is now brand new mechanism to properly stop the process tree. It is used for Grails and seems to be much better than previous solution. It even works without admin privileges (at least on Vista). Please report any problem you find.
As there were many requests for Groovy 1.6 support it is finally available in trunk. The integration also supports AST transformations. See code completion on the next picture.
There is also couple of minor fixes and improvements. The work is not finished of course. These are just most important changes for upcoming M1. Let us know what you think.
