A couple of aspects of this have come up on the post where I announced the TFS 15 RC1 and I thought it was worth a more explicit call out. Â First some context.
We have 2 release "types" for TFS - major releases (TFS 2013, TFS 2015, TFS 15, etc.) and Updates (TFS 2015 Update 1, TFS 2015 Update 2, ...). Â We think about them very differently ...
