The thread link points to the fixes and enhancements brought by the December update. At the same time there’s also a feature drop for Pixel devices, a summary of which you can see below:
For now, Video Boost seems to be exclusive to the Pixel 8 Pro despite it being done on the cloud.
The OG pixel watch supposedly syncs bedtime mode with pixel phones now. Anyone know how to activate it? Just tried after updating my devices and it doesn’t work.
