Mark, let's not spread panic. In the first place there will be another jBPM 4 release soon (version 4.4) to publish the issues fixed after jBPM 4.3 was released. The decision to stop selling support for frameworks and focus on the platform was driven purely by demand. As for jBPM 5, please understand that it was necessary. It was no longer meaningful to develop two similar projects (jBPM, Drools Flow) separately. This not only will affect jBPM 4 users but also Drools Flow users. However, in the long run, we believe this move is in the best interest of both projects.
