There weren’t any release notes available in the Settings app, but there is a support document dealing with the security contents of the update for iPhone and iPad. There’s a weird HomeKit bug that bricks your device if you rename a HomeKit accessory with a string of text 500,000 characters long. According to Apple, iOS 15.2.1 and iPadOS 15.2.1 fixes the issue. It’s not like any of us were naming accessories something a half-million characters long, but there was potential for someone to change the name of a device on your Home app and break your Apple devices in the process. You can download the update using the normal process of going to Settings > General > Software Update and following the prompts. If you notice any new features or changes after updating your device(s), leave us a comment and let us know what you found.
