This release improves the following DSLs: Actions, Semantics, Text, and Workflows. It improves the modularization of Actions and adds the ability to programmatically call an action. The Semantics DSL has an improved notation, more uniform constructs to define template-oriented transformations, and evaluation semantics. See the bundled Imp Language example to see Semantics in action.
The version of Eclipse bundled with the all-in-one distribution was updated to 3.6.2. The "xwl" file extension was introduced for the default XML Builder Persistence. The content type hierarchy was modernized and reorganized. There were various other changes.
The feature of writing "programs" mixing multiple domain languages has been enhanced with the ability to declare supported compositions. The usability of editors was improved by redesigning Focus, Selection, and DnD feedbacks. The content assist was reorganized by introducing per language submenus. The domain languages to define the structure and the behavior of a language have been extended to support aspectual models and graph structures and traversals. To facilitate debugging, a Debug Perspective was introduced with Debug and Variables views that make use of domain notations.
