This is with great pleasure that we are announcing the release of Groovy 2.4.0-beta-4.
The highlights for this release are:
a rewritten JsonBuilder for improved performance in JSON generation
a @SelfType annotation for traits
a new variant of GStringTemplateEngine capable of handling strings larger than 64k
improved support for overloaded setters
lots of bugfixes (some of which are backported in the upcoming 2.3.8 release)
a new naming convention for closures
The last point is important if your project somehow relies on the name of the closure classes as it is a potential breaking change. The reason for the new scheme is detailed here.

Thanks for your feedback and contributions!
Note that we are likely to change the scope of the 2.4 to exclude macros. There’s still a lot of work and discussion to be done on that topic, making it incompatible with our target for a 2.4 release. This feature is likely to be delayed to Groovy 2.5.
