Apple today started rolling out iOS 10.2, an update to iOS 10, the company’s latest mobile operating system.

Whereas iOS 10.1 brought the portrait mode for the iPhone 7 Plus, iOS 10.2 is significant because it introduces the TV app in which users can see what’s available through all the TV apps they have running on the Apple TV. The app’s single sign-on (SSO) feature simplifies the process. Apple first announced the TV app in October, on the same day that it unveiled the new MacBook Pro. The feature is only available in the U.S., as Apple said it would be.

Apple has been providing early access to developers and the general public in the past few weeks. The most recent beta, No. 7, came out last Wednesday, December 7.

In addition to the TV app, iOS 10.2 includes new emojis, the ability to preserve the last camera mode you used through Settings, new Celebration and Love screen effects in the Messages app, new locations for the repeat and shuffle buttons in Apple Music, and the ability to show star ratings again in Apple Music, among other things, as 9to5Mac reported last week. Additionally there’s more RAW support in the Photos app, as Apple noted in the iOS 10.2 release notes.

The SOS emergency feature is only available in India, as it has been through several of the iOS 10.2 beta releases.

Today’s update also has security fixes. For one thing, it’s no longer possible for someone nearby to overhear an iOS device speaking out a password, and people can no longer see photos or contacts on a locked iOS device, Apple said.

To get the new update, go to Settings > General > Software Update.

Update at 10:30 a.m. Pacific: Revised to reflect that the TV app is only available in the U.S.
