Today, Apple officially released iOS 11.2.1, the eighth official update to the iOS 11 operating system. iOS 11.2.1 comes a week and a half after the release of iOS 11.2, the second major update to the iOS 11 operating system, which brought Apple Pay Cash, faster 7.5W wireless charging, and a long list of bug fixes.

The biggest part of the update is a fix for an issue that could cause remote access to HomeKit shared users to not be accessible from the Home app. While fixing a recently discovered vulnerability, Apple broke this particular feature, so iOS 11.2.1 will bring it back to life for HomeKit users.

As a refresher, the HomeKit vulnerability discovered earlier this month made it possible for unauthorized access to smart, connected devices, including smart locks designed for doors in a home. Apple fixed the problem on the server-side, which patched the issue since it wasn’t tied to HomeKit hardware or specific devices. However, it required Apple to disable remote access for shared users at the time. Apple said that it would be bringing the feature back online this week.

iOS 11.2.1 fixes the autofocus bug on iPhone X and iPhone 8, which affected some users after upgrading to iOS 11.2. The update also includes fixes for other bugs that have been discovered since the public launch of iOS 11.2, as well as performance tweaks and improvements behind-the-scenes.

You can update to iOS 11.2.1, which is a small update and just under 100MB on most devices. You can update over-the-air, through iTunes or using the direct IPSW links below.
