1.4 now uses a logging table instead of funky wiki pages to log uploads, deletions, etc. When upgrading a
wiki, the data in the log pages should be imported into the logging table insofar as possible, and perhaps
the old pages redirected to the appropriate Special:Log section.

There's a partial import script in maintenance, it needs to be finished up before release and an updater
added to the set.
