When a development wish is done I want to know from which version the feature is available. So when a feedback or wish goes to the category (done) system completed status, I need to assign a version number.

Example:
100 wishes done
20 wishes done with V1.0
2 wishes done with V1.1
6 wishes done with V2.0
etc etc etc

In the future you want to have a version manager to see when, what has been deliverd.
