Are there any concerns regarding Forward/Backward compatibility with those using older versions of MR2 and ORD/MS13?
As noted, there's a schema change between the versions so the civil data will need to be upgraded. When you attempt to open a 10.07 file with the 10.08 version, you'll be prompted with this. We've updated a few of our projects and haven't run into any issues yet. I do appreciate that a backup is being automatically made, should you need to go back for some reason.
