YAWL 4.0 is out!
YAWL 4.0 is now available here for download. One of the most prominent new features is a worklet and exlet editor. Worklets allow for so-called ad hoc workflows. Workflow behaviour can be extended while a case is running. Exlets are a concept for exception handling. Everything is described in the new YAWL User Manual.
Try the new version and let us know what you think.
