In this release, face tracking has been reworked to have less of a performance impact on VRC. Some code paths that would cause tracking to get stuck were fixed, and a watchdog was added in case connection with VRC is lost.
(This is release v0.3.0 but with separate builds for ALVR and Babble)
If using ALVR, please make sure to use ALVR v20.7.0 or later.
