Apple stopped signing iOS 14.4.1 after the release of iOS 14.4.2

After releasing a new version of iOS 14.4.2 that includes a fix for a security vulnerability that has been actively exploited, Apple has stopped code signing for iOS 14.4.1.

The code signing was stopped about a week after Apple released iOS 14.4.2 to the public on March 26, which would prevent users running iOS 14.4.2 from downgrading to the old version of the operating system.

The iOS 14.4.2 update is a small-scale fix for Apple’s mobile operating system. It mainly fixes a defect that may allow bad actors to conduct cross-site scripting attacks through maliciously produced web content. Apple stated that it is aware of the vulnerability being exploited externally.

After Apple releases new software, it will periodically stop signing the outdated code to prevent users from installing the old version of iOS. This protects users from new threats and ensures that the device is running the latest software.

Apple is also testing the upcoming iOS 14.5 update, which includes the long-awaited application tracking transparency feature, and plans to launch it in the spring. It has now entered the sixth round of test versions, which can be used by developers and public software testers.
