Earlier this month, Google published details on its support site of a new Preview Program for its Home speaker. Now, the program has gone live for all users, offering them the opportunity to get a first look at new additions to the device before their general release.
However, Google insists that its Preview Program won't be burdening users with the kind of buggy software that one might expect of beta releases:
This is not “beta” software. Our intention is that Preview Program updates will be of the same quality as production version updates. You're simply getting earlier access to new features before they’re released broadly.
It added that "the Preview channel is updated shortly before the full push of our production firmwares" [sic], so any features made available to Preview Program users should make their way to the wider user base pretty quickly.
To join the Preview Program, open the Google Home app on your phone, and go to Settings, where you'll find the option to join and await the next preview release.
