Apple last week stopped signing iOS 14.8 as well, which means iOS 15.0.1 is the only publicly available version of iOS at this time, and those who have upgraded to iOS 15 cannot downgrade to iOS 14.
Apple routinely stops signing older versions of software updates after new releases come out in order to encourage customers to keep their operating systems up to date.
iOS 15.0.1 introduced a fix for a bug that prevented an authenticated Apple Watch from being used to unlock an iPhone 13 model when wearing a face mask. It also addressed a bug that could cause the Settings app to incorrectly display a storage full alert and it fixed a bug with audio meditations for Fitness+ subscribers.
