What do Blueprints version codes mean?
BluePrint’s version codes contain three numbers in the format x.x.x. The first number identifies a major upgrade involving a full development effort. A higher version number will most likely require a new purchase. The middle number identifies a significant upgrade involving product fixes, minor redesigns, texture changes or other minor improvements. A higher version number will be available as a free download. The last number indicates flight simulator version compatibility. A “1” indicates that the scenery is compatible with Microsoft Flight Simulator 2004, A Century of Flight (also known as FS9). A “2” indicates that the scenery is compatible with Microsoft Flight Simulator X (also known as FSX).
