Another week, another iOS 12.3 beta.

Apple today released iOS 12.3 beta 4 to registered developers. The update includes an updated version of Apple's TV app that includes machine learning-based recommendations, a streamlined user interface, and a new Channels section that'll let you easily subscribe to and watch content from services like Showtime, Starz, HBO, Nickelodeon, and CBS All Access.

This new TV app is expected to launch in May, so we should see the iOS 12.3 update released to the public sometime next month. Until then, developers can grab the iOS 12.3 beta 4 release over the air or through Apple's Developer Center on the web.

Also released today is watchOS 5.2.1 beta 4 for the Apple Watch. No significant changes have been found in this update so far, which suggests that it could be focused on fixing bugs and improving performance.
