Apple ceases iOS 14.5.1 code signing following release of iOS 14.6

Apple on Tuesday stopped signing iOS 14.5.1 code, effectively blocking downgrades to the operating system following the release of iOS 14.6 at the end of May. The code signing stoppage comes a week after Apple issued iOS 14.6 with new features including the activation of Apple Card Family and support for paid subscriptions in the Podcasts app.
