The Graphical Editing Framework (GEF) project team has officially released its next generation API (aka. GEF4) as part of its 4.0.0 (Neon) release. Within this talk, I want to give a demo-tour that covers (basically) all the new GEF4 components, while especially pointing out what has been achieved since the 3.10.0 (Mars) and 3.10.1 (Mars.1) releases, in which we included a first snapshot. The goal is to give a nice overview of what is provided, taking an end-user/adopter's perspective, and not going into technical details. In addition, I want to sketch how we plan to continue our journey from here, heading for a GEF 5.0.0 release with Oxygen.
