"The way messages are handled in Wiki-navigation has been changed slightly to avoid confusion. A MediaWiki page will only be treated as a magic word if it's prefixed with 'MediaWiki:'. Current messages have already been replaced by the updated content, so most of this change has already been addressed."

Could you explain this further? What if, for whatever reason, one wanted to link to a page in the MediaWiki namespace?
