Today, Apple began rolling out iOS 14.2, iPadOS 14.2, tvOS 14.2, and watchOS 7.1 for supported devices. The last update to iOS and iPadOS was iOS 14.1 on October 22.
The new versions of iOS and iPadOS add 100 new emoji, which include "animals, food, faces, household objects, musical instruments, gender-inclusive emoji, and more," according to the release notes. iPhones and iPads got a new Shazam button in the control center. Shazam, which Apple acquired just over two years ago, identifies songs algorithmically by listening to them with the microphones in the devices. Before the acquisition, it was also used as a sort of audio QR code for marketing activations during TV commercials and the like.
There are also some AirPods-related changes, including variable battery charging to preserve battery longevity (something Apple has already implemented in other devices) and notifications that let you know when your volume level is high enough to cause hearing damage. Apple promised this with iOS 14 when it initially launched.
