The links "Whatlinkshere" and "Related changed" have been removed from the sidebar of classic skin in r44780. It seems they may be redundant but wanted (see url). Some people on dewiki also complained about it, so I would suggest to just restore them, unless there are other resóns for removing them, that I'm not aware of.
