Stop signing for iOS 15.3.1

Apple released iOS 15.3.1 on February 10. This update brought important security fixes and fixed an issue that could cause braille displays to become unresponsive. An update which is therefore not major, but which is important for all those who need accessibility and more precisely braille displays.

The only version that can be installed today is iOS 15.4, which was released on March 14. And for once, this update includes a lot of new features. In particular, there is the possibility of unlocking your iPhone with Face ID while wearing a mask. It is worth noting that this requires having an iPhone 12 at least. We should also mention the availability of Universal Control, linked to macOS 12.3 on Mac. Apple has also offered 37 new Emojis, a new neutral voice for Siri in English, new alerts to limit spying with AirTags or even support for the European vaccination pass in the Health and Maps applications.

There is currently no beta version for the future update. Will it be iOS 15.4.1 or iOS 15.5? No answer for the moment. Note that there will then be iOS 16, with a presentation at WWDC in June.
