The 1.35.0-wmf.27 version of MediaWiki is blocked[0].

The new version is not deployed to any group[1], and can proceed no further until these issues are resolved:

* Call to undefined method WikiPageMessageGroup::getKeys() - https://phabricator.wikimedia.org/T249258 * Wikidata's wb_items_per_site table has suddenly disappeared, creating DBQueryErrors on page views - https://phabricator.wikimedia.org/T249565

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!
