The 1.34.0-wmf.13 version of MediaWiki is blocked[0].

The new version is deployed to group0[1], but can proceed no
further until these issues are resolved:

* PHP error from Special:OAuth: "Indirect modification of overloaded property User::$oAuthUserData" - https://phabricator.wikimedia.org/T227688
*Fatal from CirrusSearch\Job\LinksUpdate: "Call to a member function getLogVariables() on null" - https://phabricator.wikimedia.org/T227691
*Fatal on some Special:MyLanguage urls: MWException "Can't determine talk page associated with interwiki link" - https://phabricator.wikimedia.org/T227700

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!
