Today, Apple began rolling out iOS 14.4.2, iPadOS 14.4.2, and watchOS 7.3.3, and the company issued an advisory to users to update as soon as possible. Like iOS / iPadOS 14.4.1 before, this update fixes a security flaw.
Additionally, Apple released a similar security update, 12.5.2, for older devices like the iPhone 5S or 6 that cannot run iOS 14.
The release notes for iOS 14.4.2 and iPadOS 14.4.2 are minimal and simply say:
This update provides important security updates and is recommended for all users.

The same goes for the watchOS update. All four software updates (iOS 14.4.2, iPadOs 14.4.2, iOS 12.5.2, and watchOS 7.3.3) should already be available to all supported device users at this time. This is the second update since the release of iOS / iPadOS 14.4 and watchOS 7.3 in late January.
The update immediately prior to this was also an urgent fix for a security vulnerability.
iOS 14.4 was a feature update, not just a security update or a bug fix, but the added features were relatively modest. They included the camera’s ability to read smaller QR codes than before, an option to manually classify Bluetooth devices to ensure desired behavior, and notifications to let users know if the camera “cannot be verified as a new, genuine Apple camera. “. “
