Indeed this is a useful feature

There is versioning support for Add-ons in our backlog

Would be interesting to know if we need to keep more than two versions in the history: current and previous or if there are cases when you need to switch between different versions

Add rollback option in Addon to the previous version

You must manually back up the add-on before installing the new version because it is automatically overwritten.

The request is to make the Addon service version sensitive, in the sense that it can roll back the addon to the previous version at the request of the user.
