I'm long time simmer (FS9) but I'm an X-Plane newbie. I'd like a little clarification on version differences. Specifically, are older (but recent) versions of X-Plane v9 & v9.7+) compatible with V10/10.20/10.25)? In point of fact I haven't even install my new copy of 10.20+ yet, But I would like to know, as I get set to dive in to this thing, what I can (and can't) use in in a particular installation Thanks.
