The 1.36.0-wmf.3 version of MediaWiki is currently blocked at group0.[0]
The new version can proceed no further until these issues are resolved or appropriately triaged:
* Uncaught ArgumentCountError: Too few arguments to function OOUI\Tag::appendContent(), 0 passed - https://phabricator.wikimedia.org/T259745
* Argument 3 passed to CachingFallbackLabelDescriptionLookup::buildCacheKey() must be of the type string, null given - https://phabricator.wikimedia.org/T259744
Thanks for any help resolving these issues. If they're handled by roughly 14:30 PDT / 21:30 UTC today, the train can roll forward. Otherwise it can resume during US working hours on Thursday.
