Hi, was this edit made by some automated tool? Removed hooks CheckUserInsertForRecentChange and GetNewMessagesAlert are still used by the extension (although UploadVerifyFile was removed correctly). Also duplicate newhook parameters were added (there are already newhook1/newhook2 below).

The edit is based on the current extension.json.
These hooks are dynamically installed (they are not listed in extension.json) via Hooks::register()
. All three missing hooks (two mentioned above + RecentChange_save) are like that.
