I noticed something that looks strange that might be intentional, or might be a bug. While playing with the docker deployment of seafile with the notification server, I see that it asks for “seafileltd/notification-server:12.0-latest”, but this is not in fact the latest. It appears that 12.0-latest is 12.0.4, even though there is a 12.0.5 and 12.0.6 available.
