The Preview Program is a user opt-in channel that updates your Chromecast, Google Nest or Home speaker or display with the latest firmware version before it is made broadly available. This gives members of the program early access to features and improvements on their device, and helps Google find and fix bugs before features are released to everyone.

As with any new feature, Preview Program firmware updates may have issues that impact how products work. Our teams closely monitor the Preview Program to keep these issues to a minimum and correct them quickly.
The Preview channel is updated shortly before the full push of our production firmware versions.
