I upgraded a test instance of our 1.3.x mediawiki via the command line and almost everything worked perfectly. Thanks very much for making this such a painless process!
One of my users makes use of this javascript/css extension to monobook and it ceases to work after the 1.4 upgrade:

Is it simply that the HTML has changed and the getElementById calls point to non-existant elements now, or did something else change?
