> After a stack upgrade, if a host is brought out of maintenance mode it will begin to report versions for its components which don't match the stack . The current behavior today will mark this host as being "out of sync" with the current stack. When bringing a host of out maintenance mode, the web client should check versions of the components on that host. If they do not match the cluster's current stack, a warning should be presented to the administrator.
> Once the host is brought out of maintenance mode, if its component versions are different, the stack will be marked out-of-sync as it is today.
