The Boot Camp will spend the morning introducing the 4 Drools technologies: Expert, Fusion, Flow and Guvnor and will additionally cover what's new in Drools 5.1. We will also discuss the plans for jBPM3, jBPM4 and Drools Flow. The afternoon will be an open floor where you can get time with us core developers for any questions, mentoring or assistance that you would like.
