Grails 2.2 has been released recently.
- support for Groovy 2.0 (static type checker and static compilation, modularity, Project Coin syntax enhancements, Invoke Dynamic integration)
- namespace support (namespaces for Grails artifacts in plugins to avoid naming collisions)
- forked mode (fork JVM of embedded Tomcat for isolating classpaths and reducing memory footprint)
Outlook for Grails 2.3:
According to Graeme Rocher’s blog post, Grails 2.3 will solve a lot of dependency management problems (which a lot of Grails users experienced) by adding support for the dependency manager Aether. Until now Grails uses Ivy which seems to be responsible for a lot of trouble (e.g. problematic snapshot handling). Aether is the dependency manager used by Maven and should solve most issues users experienced when using Ivy.
