I want to see if it's possible to diff two different revisions of a project in subversion. I use the "Browse Changes" feature in Idea frequently, which shows the changes to the group of files involved in any single checkin. Ideally the behavior I'm looking for is to be able to select any 2 revisions in the Changes panel of the Changes Browser using control-click, and then have the right Changed Files panel show the conglomerated changes between those revisions. If I click through the revisions individually I can see the changes on each checkin, but I want to see the total set of changes across a bunch of checkins. Another way to think of it is that for single files I can show the history and then diff between arbitrary versions; I want to be able to do that across an entire project in subversion.
Does anyone know if this is possible? I'm on Idea 6.0.5, is this something I would need to upgrade to version 7 to be able to do?
