Apple released a new security update for iOS 26.3 beta users. There are two versions released by the technology giant and both are here to test a new invisible protection system.
Compared to the usual beta launch, this version does not contain bug or security fixes for certain holes. The main purpose of this launch is to test the reliability of a new system called Background Security Improvement which has been updated.
Actually, the security update system has been overhauled through the iOS 26.1 update. Background Security improvements are already installed on all iPhones running the OS, but Apple has not yet used the system.
The new company is trying to test its features to ensure the system runs stably. The location to install this update is also not in the usual software update menu. Users must search for it manually through the Privacy and Security menu in the phone's settings.
The installation process still works like a standard update, but gives users more flexibility. Once installed, users will have the option to remove the update again from the same page. If the user chooses to remove the update, the iPhone will automatically restart.
The two versions that Apple released for the iOS 26.3 beta this time are (a) and (b). Version (a) was released earlier, while version (b) was launched about two days after the first launch. This shows that Apple is ensuring that its security system is running well before the stable release for global users.
It is not yet known when the stable version of iOS 26.3 will be released. However, looking at the pattern of launching Apple's OS from year to year, iOS 26.3 is expected to be available by the end of January.
