But in my opinion it has not work.
With r99241 in FlaggedRevs.i18n.php the message 'flaggedrevs-hidereviewed' in language de was changed in svn, but that message is not updated, for example on en.wiki: [[MediaWiki:Flaggedrevs-hidereviewed/de]].
Please check if LocalisationUpdate is working correct on WMF wikis.
