Migration guide to 4.x

Every new version of YAKINDU Statecharts Tools contains a lot of new features and improvements. Since today, every new released version was fully backward compatible to older versions due to careful design.
However, with the new major release of version 4.0, we decided to leave some old perceptions behind. This document will cover all incompatible changes that were introduced from version 3.x to version 4. Read this document carefully to ensure a seamless migration from your existing 3.x models to the latest version 4.0.
