User blog comment:ComboLuigi2000/The mistake of UCP (And how it can be improved)/@comment-36107211-20200823030253/@comment-24258073-20200823032035

Yes but the UCP platform is automatically better, as it uses a much more updated version of MediaWiki. While I will miss those features that I have come to love on the legacy platform, the legacy platform itself is severely outdated and should have been replaced years ago.

Sites like Wikipedia update their versions of MediaWiki constantly, and while they've been doing that, Fandom's version of MediaWiki has steadily become more and more outdated. There isn't a single site that I use that uses a version of MediaWiki as ancient as this one.
