I just purchased the Public Beta 9, so the package also includes the xPlane 10 full version just in case 11 is broken. X-Plane 11.00 is the initial version of the newest flight simulator from Laminar Research. X-Plane 11 includes new features such as new aircraft, a new user interface, tutorials, service vehicles, European autogen, and a new lighting, sound and effects engine. It included numerous flight model updates, an entirely updated default fleet of aircraft, redone FMS & GPS units, Navdata updates, and recut global scenery.
