Groovy 2.1.0 arrives ready to invoke dynamically

The developers of Groovy have announced the release of Groovy 2.1. The new release of the JVM-based language now has full support for Java 7’s “invoke dynamic” byte code and API, which allows dynamic languages on the JVM to make dynamic method calls as efficiently as Java programs make static method calls. Groovy 2.0 had support for most method calls using “invoke dynamic”, but now all method calls make use of it. The GPars concurrency framework is also now bundled with Groovy 2.1.
