Two weeks after launching the last iOS 12.3 beta, Apple today unleashed a new build.

iOS 12.3 beta 3 is available to registered developers both over the air and for manual loading. If you'd prefer the OTA route, you can go into your iPhone or iPad's Settings app and select "General" followed by "Software update". The update is also available for download on the web from Apple's Developer Center.

The update to iOS 12.3 includes a refreshed version of Apple's TV app with a recommendation system that uses machine learning to suggest new shows for you to watch. A new Channels section will let you subscribe to and watch services like CBS All Access, HBO, and Nickelodeon.

There's no public launch date for iOS 12.3 quite yet, but Apple has said that its new TV app will launch in May, so we could see the iOS 12.3 update launch then.

Apple today also released watchOS 5.2.1 beta 3 to developers. There's no word yet on which new features or other improvements Apple will include in this update.
