One of the arguments in the constant battle “iOS vs. Android” is support and its duration. It is easier for Apple to maintain its devices, because they do not have such a variety of gadgets as other manufacturers. And that is why some, for example, security patches can be obtained on already very old devices, such as the iPhone 5s, which turns 10 years old this year.
Along with updates to current systems, users of older versions also received some such patches this week. These are OS 12.5.7, iOS 15.7.3, iPadOS 15.7.3, macOS Big Sur 11.7.3, and macOS Monterey 12.6.3. At the same time, the gap between iOS 12 and iOS 15 is explained by the fact that all devices that support iOS 13 can also be updated to iOS 15.
But these devices did not get fundamentally new functionality. Updates are focused purely on security and solving known problems: AppleMobileFileIntegrity, curl, dcerpc, DiskArbitration, DriverKit, Intel Graphics Driver, PackageKit, Kernel, Mail Exchange, Maps, Screen Time, Weather, WebKit, and Windows Installer.
