YAWL 5.0 is out now and ready for download here. The most prominent feature of this major release is the new user interface.
For everyone who wants to give it a try, I encourage you to use it. If you find any issues let me know.
I am looking forward to updating all YAWL tutorials now. It will take some time and they will replace the existing tutorials in the YAWL playlist. So if you want to get notified when they appear, subscribe to my Youtube channel.
