Removed outdated MAVLINK v0.9 version as QGC does not work with this version. Added feature to import COLLADA terrain model and visualize model in 3D view.

Added multi-UAS support to QGCRGBDView. Fixed display timeout issue on computer for which data source is not time-synchronized.

Code changes to reflect new header information (sysid, compid, timestamp) in protobuf messages. Added protobuf message timeout; old messages will not be visualized. Fixed getParameterValue in ParamManager; the method can segfault if the component id or parameter id is not valid.

Added visualization of obstacles. Fixed relative font path issue in 3D widgets by using QFont within osgText::Font instead of using static font filename.

Enabled visualization of point cloud data via Protocol Buffers serialization and extended_mavlink_message.

Added to 3D view user switching between local and global coordinate system. Fixed bug in WaypointView: new instance used to assume frame is global.

Fixed imagery rendering issues. Robot position in Pixhawk3DWidget is now derived from the global pose (lat/lon/alt) instead of the local pose.

Added visualization of point cloud data from Kinect camera. Colorized point cloud visualization to follow soon.

Fixed bug in check for osg/osgEarth dependencies for QGC. The Q3DWidget instance runs if OpenSceneGraph libraries are installed. The terrain feature is enabled if osgEarth libraries are installed.
