openArchitectureWare 4.3 is mainly a bugfix release. We've fixed 102 bugs with a lot of help by active community members. Special thanks go to Michael Clay and Manfred Klug for providing a lot of patches and feedback.
In addition to the bug fixes we introduced two new components: A generic editor, which can be used to edit and validate dynamic EMF models without any need for using EMF's generator or installing DSL-specific editors into the workbench. The other component is an Adapter to EMF's Validation Framework, which makes the old GMF adapter obsolete.
