Group0 wikis (mediawikiwiki, test2wiki, testwiki, testwikidatawiki, and
zerowiki) are running version 1.28.0-wmf.20 of MediaWiki and extensions.
All other wikis are running 1.28.0-wmf.18.
Tomorrow there will be a shortened train schedule in the normal train
deployment window during which 1.28.0-wmf.20 will be pushed to all
wikis.
Any blockers to this plan are tracked on Phabricator[0].
Thank you for all your help and patience while we get the train
schedule[1] back on track!
