I maintain a number of snaps and regularly receive messages about packages that have been updated in the Ubuntu Archive, typically because of a USN.

Since early August these messages have referred to store revisions that have been superseded.

“Revision r108” was superseded on 20 July.

It would appear that the notification messages are being generated from outdated information about the snaps.
