改进：

• closures are now "callable" (inheriting from java.util.concurrent.Callable)
• new AST transformations like
  • @Log to inject a logger in your classes
  • @ScriptField for creating a field in a script (should be renamed to @Field in the next beta)
  • @PackageScope now working also on methods and classes (not just fields as before)
  • @Synchronized for providing safer synchronization semantics
  • @InheritConstructors to inherit constructors, like often the case when extending exception classes
  • @IndexedProperties to add JavaBeans indexed property support
  • @AutoClone providing automatic cloning support to your beans
  • @AutoExternalize providing automatic externalization of your POGOs
  • @Canonical adding proper equals(), hashCode(), toString() methods
  • @EqualsAndHashCode adding an equals() and hashCode() method
  • @ToString for creating a default readable toString() method
  • @TupleConstructor for adding a tuple constructor
• an additional syntax for strings, with $/.../$, to circumvent various escaping corner cases, like for example $/a/b\c$$ $//$
• new GDK methods like Map.countBy{}, Map.collectEntries{}, Date.putAt() (subscript operator), Date.updated()
• + obviously all other incremental improvements and new features from the Groovy 1.7 branch like
  • the new String methods like tr(), stripMargin(), stripIndent(), (un)expand(), 
  • Map's withDefault{} method, 
  • Closure's ncury() and rcury()
  • Sql's withBatch{} and withTransaction{}
