Only days after the LG G Watch and Samsung Gear Live retail launch there's another Android Wear firmware update starting to hit devices, and it seems Samsung's smartwatch is first with the new build. Multiple Gear Live owners have told us they're receiving a small over-the-air update to build number KMV78X, from the earlier KMV78V.
It's not yet clear what's new in this latest build, but it's possible it has something to do with addressing the recently-discovered bug with paid apps on Android Wear. (Update: Nope.) So far there are no reports of the LG G Watch receiving the KMV78X update, though assuming this patch doesn't just address Gear-specific issues, the LG-built watch should follow in short order.
Android Wear owners can go to Settings > About > System updates to see if their update is ready yet. Be sure to shout out in the comments if you're already updated.
