The 1.35.0-wmf.31 version of MediaWiki is blocked[0], and has been
reverted to group0.
The new version can't proceed beyond group0 until this issue is resolved:
* T252079: mw.wikibase.getLabelByLang('Q1','en') returning nil today

Assuming a fix, the train will resume, at the earliest, during the
European backup conductor's workday.
Thanks for any help in resolving this issue.
