iPhone owners, the time to update is here again.

Apple today launched iOS 12.3. It’s now available to iPhone and iPad devices running iOS 12, and you can get it by launching the Settings app on your iOS device and then selecting “General” followed by “Software Update”.

The update to iOS 12.3 focuses largely on Apple’s refreshed TV app. There’s a streamlined user interface included as well as machine learning-based recommendations. Apple has also included its new “Channels” feature, which helps you subscribe to video streaming services and watch shows without having to jump between third-party apps. Some of the services available in Channels include HBO, Showtime, Starz, Nickelodeon, and CBS All Access.

Another new feature of Apple’s new TV app is Family Sharing, which lets up to six family members share their subscriptions using their Apple ID and password. You can also download shows and movies for offline viewing.

Apple Watch owners can also grab the update to watchOS 5.2.1 today. This update adds support for the ECG app and irregular heart rhythm notifications in Croatia, Czech Republic, Iceland, Poland, and Slovakia. Also included is a fix for a bug where the numbers on the Explorer watch face would not appear.

You can get the update to watchOS 5.2.1 by launching the Watch app on your iPhone, selecting “General”, then going into “Software Update”.

Below you can find the full changelogs for both updates so that you know precisely what new features and bug fixes that you’re installing.
