Following the introduction of iOS 14.5.1 yesterday and iOS 14.5 last week, Apple has stopped signing iOS 14.4.2 and iPadOS 14.4.2. With this move, if we need to restore one of our devices we will, at least, to version 14.5.1 ensuring that we enjoy all the security fixes and performance improvements of the version.
An update with important security improvements
Apple regularly stops signing the previous versions of the different operating systems so that the devices, for example after a restore, install the latest versions. In iOS 14.5.1 Apple has fixed several security flaws related to WebKit and has improved the operation of the App Tracking Transparency.
The servers of the apple company thus stop signing old versions to ensure that all devices are always the latest version available. An important safety mechanism that prevents devices from being left behind when it comes to safety.
We are currently testing iOS 14.6 in beta, a version that will surely we will see launch in the coming weeks and that brings several important changes such as the rumored Apple Music Hi-Fi.
As we have mentioned on other occasions, software updates go far beyond new functions. They bring much more important and at the same time unknown new features: bug fixes and security improvements.
