This is a belated summary of *last week*'s deployment of the 1.37.0-wmf.15 branch of MediaWiki, extensions, and skins (also known as "the train").

The primary person in charge last week was Antoine (hashar) Musso, with Ahmon Dancy as backup, both from the Wikimedia Foundation Release Engineering team.

The summary/blocker task for this week is: https://phabricator.wikimedia.org/T281156

* trainbow – a neologism meaning "happy and successful train" — a portmanteau of "train" and "rainbow"!
