Release Date: Sep 22 2025, 12:00 AM

2025 week 39 1.45-wmf.20 Changes wmf/1.45.0-wmf.20

This MediaWiki Train Deployment is scheduled for the week of Monday, September 22nd:

Monday September 22nd	Tuesday, September 23rd	Wednesday, September 24th	Thursday, September 25th	Friday
Backports only.	Branch `wmf.20` and deploy to Group 0 Wikis.	Deploy `wmf.20` to Group 1 Wikis.	Deploy `wmf.20` to all Wikis.	No deployments on fridays

See https://wikitech.wikimedia.org/wiki/Deployments for full schedule.

How this works

Any serious bugs affecting wmf.20 should be added as subtasks beneath this one.
- Use this form to create 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.

I'm not sure if we consider T405511: TypeError: GrowthExperiments\NewcomerTasks\Task\TaskSet::__construct(): Argument #4 ($filters) must be of type GrowthExperiments\NewcomerTasks\Task\TaskSetFilters, array given and/or T405514: InvalidArgumentException: 'type' parameter is mandatory train blockers, but they now both have fixes attached to them.
