2026 week 40 1.47-wmf.22 Changes wmf/1.47.0-wmf.22

This MediaWiki Train Deployment is scheduled for the week of Monday, September 28th:

Monday September 28thTuesday, September 29thWednesday, September 30thThursday, October 1stFriday
Backports only.Branch wmf.22 and deploy to Group 0 Wikis.Deploy wmf.22 to Group 1 Wikis.Deploy wmf.22 to all Wikis.No deployments on fridays

How this works

  • Any serious bugs affecting wmf.22 should be added as subtasks beneath this one.
  • Any open subtask(s) block the train from moving forward. This means no further deployments until the blockers are resolved.
  • If something is serious enough to warrant a rollback then you should bring it to the attention of deployers on the #wikimedia-operations IRC channel.
  • If you have a risky change in this week's train add a comment to this task using the Risky patch template
  • For more info about deployment blockers, see Holding the train.

Thanks for the risky patch notice @TheresNoTime. It's rare that we rollback test wikis, but if we need to, we'll revert https://gerrit.wikimedia.org/r/1343957 first (cc @brennen).
