User blog comment:MisterWoodhouse/Fandom is upgrading to a modern version of MediaWiki/@comment-25404524-20190621032320/@comment-9605025-20190625003604

There is a ton of code that works behind the scenes to make wikis work. The version Wikia currently uses is way out-of-date. The plan is for them to upgrade to a more recent version. In the long run, this will probably result in more features being available. In the short run, there might not be much of a difference as far as basic users are concerned.
