StarUML 3 has been released. This release includes API enhancement. APIs for extension are changed. As stated on release post:
It causes that extensions for V2 will not work in the new V3 and they are required to be updated with V3 APIs. APIs for V3 are much more easier and simpler powered with electron’s APIs and ECMAScript 6 support.
In other words, you can't use the latest version of staruml-ruby (0.1.6) in StarUML 3. staruml-ruby will be available for StarUML 3 soon.
