For a long time in the Ruby community, complex workflows have caused confusion, and we limited ourselves to half-baked state machines on database models. With Trailblazer 2.1, workflows become the central element of designing and implementing software. Trailblazer now supports the BPMN standard and takes over the flow control, while your team focuses on implementing what will happen.
