Whether and how to update to ROCK Build (148) [Solved]

I saw in the release notes section the announcement that ROCK Build (148) has been released. I suspect that this is the operating system for the ROCK, though the announcement does not say so. My ROCK says that it’s operating system is Build (76). I’ve tried to determine whether I should do anything about this, and how to do it. I’ve received no update information in the Roon app. Perhaps someone can clear up my confusion.

Well, I rebooted my ROCK, and it then told me about the update, which I installed. So interesting, but otherwise, never mind.
