The 1.35.0-wmf.31 version of MediaWiki is currently blocked[0], and has been reverted to group1.

The new version can't proceed to all wikis until this issue is resolved:

* Increase in "Main slot of revision [number] not found in database!" after deploy of 1.35.0-wmf.31 to all wikis - https://phabricator.wikimedia.org/T252156

If all issues are resolved before 15:00 Pacific / 22:00 UTC today, the train can proceed to all wikis. Otherwise it will resume Monday, May 11th.

Thanks in advance for any assistance.
