This will be the first version of BPMN2 Modeler that will participate in the Eclipse simultaneous release train.
The release is focused on improving BPMN 2.0 spec compliance as well as UI enhancements in the following areas:
1. Add support for BPMNLabel elements.
2. Improve usability of Choreography and Conversation elements.
3. Add extensions for model element presentation (color, font, linestyles, etc.)
In order to accomplish 1. we have had to make some breaking API changes, and have taken the opportunity to clean up the code and refactor some classes.
