The 1.34.0-wmf.14 version of MediaWiki is blocked[0].
The new version is deployed to {group0}[1], but can proceed no further until these issues are resolved:
* TopicListBlock.php sort order params - https://phabricator.wikimedia.org/T228406
* RevisionFormatter.php: Unknown content format - https://phabricator.wikimedia.org/T228417
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
