I purchased X-Plane thru Steam and can't seem to find the official update. Maybe they haven't posted it yet. After you mentioned that it existed, I discovered that it has been out for several weeks. Just wondering how you managed to update it in Steam, or did you purchase it directly from the retailer?
BTW, new to flight sim, but I am digging it. Purchased Areofly FS 2 a couple weeks back and already have 30 hours into it. X-Plane looks really cool.
