The 1.37.0-wmf.3 version of MediaWiki is blocked[0].

The new version is deployed to {group(s){0,1,2}}[1], but can proceed no further until these issues are resolved:

* T281361 TypeError: Argument 2 passed to Wikibase\Client\DataAccess\Scribunto\WikibaseLanguageIndependentLuaBindings::trackUsageForSitelink() must be an instance of Wikibase\DataModel\Entity\ItemId, instance of Wikibase\MediaInfo\DataMo https://phabricator.wikimedia.org/T281361

Once these issues are resolved train can resume. If these issues are resolved on a Friday the train will resume Monday.

Thank you for your help resolving these issues!

-- Your humble train toiler
