Hi,
I am interested on understanding how do you use the concept of Versions into the common understanding of Project management.
I guess that I would require versions only for files as a DMS (Document Management System)

I am using Issues as Tasks, sincé Tasks are not a versión dependent attribute I would at least disable it, to avoid any confusion.

However, the milestone concept is not present.
To carry this out, I am using Tasks as Stages and sub tasks as tasks.
But a Stage is not really a Milestone.

I would like to hear some recomendations
