Loads of additions, improvements and fixes.
Could you expand your 'Audio: Set listener orientation'? How will that affect the audio? Will 3d sounds behind the listener sound different than in front?
Audio has long had a positioned sounds feature, but the listener was always pointing at the layout. It now lets you rotate the listener, e.g. to match a 3D camera. As ever, positioned sounds simulate the sound being in a certain position using a mix of panning and audio processing effects.
