+MediaWiki 1.9 and later no longer keep default localized message text
+in the database; 'MediaWiki:'-namespace pages that do not exist in the
+database are simply transparently filled-in on demand.
+
+The upgrade process will delete any 'MediaWiki:' pages which are left
+in the default state (last edited by 'MediaWiki default'). This may
+take a few moments, similar to the old initial setup.

+Note that the large number of deletions may cause older edits to expire
+from the list on Special:Recentchanges, although the deletions themselves
+will be hidden by default. (Click "show bot edits" to list them.)
