General:

• Fixed an issue that prevented controller bindings from loading for certain games, including Google Earth VR and Thumper.

Audio:

• Audio: downmix and binaural rendering now have matching volume across all formats.

Accessibility:

• Added accessibility option for users who want to limit eye tracking to a single eye. VR Settings -> General -> Track Dominant Eye Only. (requires enabling “show advanced settings”)
