Apple has stopped signing iOS 15.4 now that iOS 15.4.1 is out

Apple has now stopped signing iOS 15.4, since iOS 15.4.1 was released in the past few days. iOS 15.4.1 was released earlier in March and fixes a few issues, including the battery drain issue which was introduced with iOS 15.4.

iOS 15.4.1 also added support for Universal Control on the iPad, between it and a Mac and the ability for an iPhon to be unlocked while wearing a mask.

Apple has also stopped signing tvOS 15.4 and HomePod OS 15.4.
