After the introduction of iOS 14.3 three weeks ago, Apple has stopped signing iOS 14.2 and iOS 14.2.1. With this move, if we need to roll back any of our devices, we’ll be upgrading to at least version 14.3, making sure we take advantage of all the security fixes and performance improvements in the version.
The importance of keeping our devices to the latest version available
Apple regularly stops signing previous versions of various operating systems so that devices, for example after a restore, install the latest versions. On iOS 14.3 Apple introduced the ProRAW format for the iPhone 12 Pro and Pro Max,
We are currently testing iOS 14.4 in beta, a version that we will surely see launched in the coming weeks and which, at least in its first beta, focuses on improving the performance of our iPhone or iPad
Thus, the servers of the Apple company stopped signing the old versions to ensure that all devices are always the latest version available.
As we’ve mentioned on other occasions, software updates go way beyond new features. They bring new features that are much more important and at the same time unknown: bug fixes.
