SpringSource and the Groovy Development Team have worked together to release this maintenance version of Groovy 1.6.2.
You can have a look at the JIRA change log report for further details.
A regression that had been introduced in 1.6.1 with regards to the usage of Spring dynamic proxies has been fixed. A potential memory leak has also been solved, as well as some issues with the package names exposed in our OSGi-fied manifest.
You'll also notice some minor improvements to Groovlets and Groovy Templates, for those having fun with Groovy on Google App Engine, for instance for simplifying redirects, forwards and includes, and for customizing the binding passed to the groovlets and templates.
You can download Groovy 1.6.2 at the usual place.
Have a Groovy weekend!
