Version 1.6.6 of Groovy has been released. Groovy is
a JVM hosted scripting language that "builds upon the strengths of Java but has additional power features inspired by languages like Python, Ruby and Smalltalk."
Groovy got a little play for a couple of years, but the smart money is now betting on Scala. Name aside, Groovy just never caught a groove.
1.6.6 is a bug fix release.
