After the release of iOS 14.7 to the public last week, Apple has now stopped signing iOS 14.6. iOS users who are running iOS 14.7 on their iPhone will no longer be able to downgrade back to iOS 14.6.
After releasing new software versions, Apple stops signing older versions of software to encourage customers to have their devices up to date. iOS 14.6 was released in May which introduced new AirTag features, voice control improvements, lossless and spatial audio support, and more.
With the release of iOS 14.7, Apple brings Podcasts updates, MagSafe Battery Pack support, Apple Card Family sharing, and more. The software version was further updated to iOS 14.7.1 to fix an Apple Watch bug that occurred on iPhone models with Touch ID.
