This is an early summary of this week's deployment of the 1.36.0-wmf.37 branch of MediaWiki and its extensions (also known as "the train"). The primary person in charge this week is Mukunda Modell, with Antoine Musso as backup, both from the Release Engineering team. The summary task for this week is https://phabricator.wikimedia.org/T278343 This week's deployment is still ongoing. The train is at group 1, and will hopefully move to group 2 later today, but I'm writing this ahead of time due to a time zone issue (hello from the future!). There were some problems with getting a late patch included in the train branch, initially, but the train got started pretty much on time. As of writing this email, there is one blocker task: - T279008: mw-parser-output now clears after block, which is a noticeable change for Category pages where infoboxes used to render floated alongside the automatic content https://phabricator.wikimedia.org/T279008 There has been some back and forth about tasks as issues have been investigated and various tasks have either been raised to being blockers or demoted from that status without the issue being resolved. For details, please see the summary task. (I'm trying to keep these summaries short, but each week could be turned into a suspense novel.) As usual, a whole bunch of people helped to find, triage, analyze, fix, or work around problems this. Release Engineering thanks everyone, without help we wouldn't be able to deploy MediaWiki. - Amir Sarabadani - Bartosz Dziewoński - C. Scott Ananian - Daniel Kinzler - DannyS712 - Dylsss - James D.
