On my dashboard update-notifications.php is reporting its version as 3.0.4 instead of the correct version (which is installed) as 1.0.4.
I debugged this and found that the version being reported for update-notifications.php is
actually the version found in the header of db.php (Multi-DB). When I change the version in db.php it appears as the version for update-notifications.php in the dashboard!
Note that Multi-DB version information doesn't appear at all in the Dashboard.
Here is what my Dashboard looks like under Super Admin->WPMU DEV.
Note that the other strange item is that Ad Widget reports as version "2.0" while the latest
version is "2".
