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 roll back any of our devices, we’ll be upgrading to at least version 14.5.1 making sure we take advantage of all the security fixes and performance improvements in the version.
An update with significant security improvements
Apple regularly stops signing previous versions of different operating systems so that devices, for example after a restore, install the latest versions. In iOS 14.5.1, Apple fixed several security vulnerabilities linked to WebKit and improved how application tracking transparency works.
The servers of the Apple company thus stop signing the old versions to ensure that all devices are always the latest version available. An important security mechanism that prevents devices from being left behind when it comes to security.
We are currently testing iOS 14.6 in beta, a version that will surely be we will see the launch in the next few weeks and it brings several big changes like the rumored Apple Music Hi-Fi.
As we’ve mentioned on other occasions, software updates go way beyond new features. They bring much more important and at the same time unknown new features: bug fixes and security improvements.
