The pre-release tunes were discovered by developer Guilherme Rambo, who also uncovered info about the then-unnanounced iPhone 8 and iPhone X earlier this year when Apple released its first batch of HomePod firmware. Apple today released iOS 11.1 for compatible devices.
Finally, tvOS 11.1 is rolling out to Apple TV (4th gen) and Apple TV 4K. There are more than 70 new emoji included in iOS 11.1, including broccoli, a sled, a pie, a vampire, a hedgehog, a face with a monocle, a shushing face, and many more.
macOS High Sierra 10.13.1 is out too, with new emoji of its own, a fix for the KRACK Wi-Fi vulnerability, and more reliable Exchange message syncing in Mail.
The KRACK exploit affects the WPA2 security protocol, a standard for Wi-Fi security used on nearly every Wi-Fi router. With the iOS 11.2 beta, Apple has removed the animations from the calculator app, so calculations can be conducted rapidly with no need to pause between entering numbers to obtain the correct result. Users can now stream Apple Music through their data connection, or Wi-Fi, of course. The result for normal humans should be six but a quirky iPhone bug causes the native iOS 11 Calculator to give a different result. There are no new features to speak of in this case, it's all about unnamed bug fixes and performance enhancements.
Stay tuned for full release notes and grab the latest software update from the Settings app on iPhone, iPad, and iPod touch.
