The main topics for 0.12.0 release of Graphiti are to continue to work on enabling Graphiti to leave incubation and implementing round offs to make the framework more flexible and easy to use.
Graphiti is part of the Mars Eclipse release train since M1. Mars will contain the Graphiti framework, examples, tools and tests. Graphiti has joined the release train for the first time with Eclipse Indigo.
