tl;dr if the timing of the weekly MediaWiki branch cut affects you, please join the discussion on T242446[1]
Soon we will switch on full automation of the mediawiki branch cut! 🎉
In so doing we will switch from using the make-wmf-branch script in release/make-wmf-branch. Instead we will use release/make-release/branch.py and the associated config will now live at release/make-release/settings.yaml. The documentation on wiki has been updated to reflect the change with instructions about how to set up and use branch.py.
There is more to this change than just using a different script, however. In order to turn on full automation we need to decide on when to run the branch cut. The current practice is to do it at approximately noon pacific on Tuesdays. We could move this to an earlier time but I think we should have a larger discussion about the timing of the branch cut and how that affects various teams and workflows.
If the timing of the branch cut affects your team, your feedback is requested on the task at [1]
