The 1.41.0-wmf.27 version of MediaWiki is blocked[0].

The new version is currently deployed to testwikis, but can proceed no further until this issue is resolved:

* T346800 - startupregistrystats-testwiki periodic job fails - https://phabricator.wikimedia.org/T346800

Once this issue is resolved train can resume.

Thank you for any help resolving these issues!
