After I544cdfa75c7472f2d98b2561bc6f6f9c2d2ad639 (dieWithError and checkUserRightsAny), this is the oldest MediaWiki version AbuseFilter can be run on. AbortMove was removed from MediaWiki in 1.25, UploadVerifyFile is only relevant for 1.27 and older. (Replaces I1e962217c3b20d901a5742cf76339a3f488a6e97.)
