In the early hours of this morning, Apple urgently released the official version of iOS 16.4.1, so what are the changes in this update? Let's take a look at it together.
The updated version number is: 20E252, according to the update file, this update is mainly bug fixes and security updates, and does not mention any new features. Some of the bugs include Siri not responding, push watch emoji does not display skin color options.
Then I also updated it, and I didn't find any new features. However, we also found that iOS 16.4.1 fixed two vulnerabilities in the official website content: IOSurfaceAccelerator and WebKit.
From the official information given by Apple, these two vulnerabilities have been exploited, because of their high risk factor, so Apple urgently launched iOS 16.4.1 system to repair.
In addition to the release of the iOS 16.4.1 system, Apple has also closed the verification channel of iOS 16.3.1, that is, if you are now a system above iOS 16.3.1, then you will not be able to downgrade.
