The final YAWL 3.0 Release is now available

Forums: 

YAWL 3.0 has just been released. There are a large number of improvements to the new process editor (over the 3.0beta release). The engine and services also have a number of improvements. The editor, YAWL engine and all services can now be auto-updated, too, so you will always have access to the latest builds of the entire YAWL system.

Workflows for testing the YAWL Android Client

I created three workflows that helped me find the flaws and bugs in the different YAC versions, which I am going to describe here.

Test data types

The first workflow was created to test different data types in YAWL and how they are displayed:
