The 1.36.0-wmf.27 version of MediaWiki[0] is at group0[1], and is currently blocked. Thanks to James Forrester, RhinosF1, abi_, Nikerabbit, Urbanecm, Daimona, Ladsgroup, Marostegui, and probably others I'm forgetting for getting us this far.
The new version cannot be deployed further until this issue is resolved:
* PropertyInfoSnakUrlExpander: Bad value for parameter $snak->getDataValue(): must be a DataValues\StringValue - https://phabricator.wikimedia.org/T272508
Thanks for any help resolving this issue. If a fix is merged with reasonable time to deploy before the 15:00 Pacific deployment cutoff, the train will continue to group1 today.[2] Otherwise it will resume in the European morning window at earliest.
