There are basically no functional updates in this update, mainly to fix 16 vulnerabilities. The 16 fixed defects cover categories such as Kernel, Find My, WebKit, and Apple Neural Engine. Two of them may have been actively exploited, Apple said.
Since iOS 17 is about to go live, it is not expected that iOS 16 will bring any new user-oriented features. It is worth mentioning that this version may be one of the last updates of iOS 16, and the follow-up will shift to security-focused updates.
In addition, Apple iOS 17 also removed support for iPhone X, iPhone 8 and iPhone 8 Plus. This means that these phones will usher in the final iOS 16 update, but in fact, Apple has still been releasing security updates to older hardware for years, so you don’t have to worry.
It should be noted that due to the configuration cache of Apple’s regional node servers, there may be a slight delay in the detection of upgrades in some places, usually within half an hour, not too long.
