If somebody asks what are the differences between two editions of the same application, how should the question be tagged? For example [Difference between resin and resin pro](http://superuser.com/questions/104133/difference-between-resin-and-resin-pro) is currently [tag:untagged] and I have no idea what would be the proper tag, despite the question looking to me like it's on-topic.

Please note that a not-very-popular [tag:windows-edition] tag already exists. Maybe it should be renamed to a more general [tag:software-edition]?
