Prepar3d version 2.2 is out now with a full list of improvements. The update appears to be heavily supported by ORBX and I can understand why! List of improvements include:
Autogen out of memory crash fixes
The inclusion of the v2.1 panels ‘hotfix’ that reverted changes to the ContentErrorLogging system that caused previously compatible aircraft to not work
New cloud shadows feature as well as several new shadow system optimizations
A new sample for the Prepar3D Development Kit (PDK) API – Oculus Rift integration
Native radar support for Prepar3D developers
A redesign and refactor of the legacy Flight Recorder system
A new FlightInstructor mode for SimDirector, as well as several other SimDirector enhancements
Several other community and developer issues resolved
