Tech News announcement

Starting March 25, 2025, The Editing team will test a new feature for Edit Check, at a few wikis: [[ mw:Help:Edit_check#Multi-check | multi-check ]]. For half of the newcomers, we will show all [[ [[ mw:Help:Edit_check#ref | | Reference Checks ]], while the other half will continue getting the usual experience (one Reference check shown). The goal of this test is to see if users are confused or discouraged when shown more References checks.

At these wikis, the tags used on edits that show References check will be simplified, as multiple tags could be shown within a single edit. Changes to the tags are documented on https://phabricator.wikimedia.org/T373949.
