TRAILBLAZER-WORKFLOW is another dream ‘o mine come true. It allows creating long-term processes (or state machines) based on BPMN diagrams that can be modeled using our editor.

A major improvement here is the ability to maintain more than two explicit termini. In 2.0, you had the success and the failure termini (or “ends” as we used to call them). Now, additional ends such as not_found can be leveraged to communicate a non-binary outcome of your activity or operation.

Statecharts are a formalism for modeling stateful, reactive systems. This is useful for declaratively describing the behavior of your application, from the individual components to the overall application logic.
