In addition to including AspectJ 1.6.9, this release includes a number of new features for making intertype declarations (ITDs) first class citizens in the editor. Java search now includes references and declarations of ITDs. Rename refactorings are now ITD-aware. And we have introduced the new pull-out refactoring, that can pull out your Java fields, methods, and constructors into an Aspect and convert them into an intertype declaration (this refactoring is the converse of the push-in refactoring that was introduced in 2.0.0.
