The 1.34.0-wmf.16 version of MediaWiki is blocked[0], after a brief period of being unblocked. Thanks to Jdlrobson and everyone else who worked on unblocking the earlier issues.
1.34.0-wmf.16 cannot proceed to group1[1] until these issues are resolved:
* PHP Warning: Wikibase\Lib\Store\Sql\WikiPageEntityRevisionLookup::getEntityRevision: Entity not loaded - https://phabricator.wikimedia.org/T229482
Once these issues are resolved, the train can resume. If these issues are resolved on a Friday the train will resume Monday.
Thank you for your help resolving these issues!
