True: transient needs to be uploaded too.
I tested locally with my own updated transient. But I actually hadn't finished testing; there's an issue where the test suite runs okay in the CI systems (minimal install) but gets a failure running an emacsclient and blocking on wait for the recursive edit to finish. For this reason, I didn't actually mean to upload magit. I pushed magit 4.1.1-1 to salsa; someone else dput it. I dput 4.1.2-1 because there's no practical difference between the two.
