Apple's beta testing of iOS 12.3 rolls on today.
iOS 12.3 beta 2 is now available to registered developers. The update brings with it a new version of Apple's TV app that includes a new, streamlined look and a machine learning-powered recommendation system that'll suggest new content for you to watch. There's also a new Channels section that'll let you watch services like CBS All Access, HBO, and Nickelodeon after subscribing to them.
This new iOS 12.3 beta is available for download over the air for anyone that's registered as an iOS developer. It's also available for devs in Apple's Developer Center on the web. A version for public testers as part of the Apple Beta Software Program should be available in the coming days.
Apple hasn't said when iOS 12.3 will launch to the public. The company is planning to launch its new TV app to the public in May, though, so we should see a full iOS 12.3 release next month as well.
Also rolling out to developers today is watchOS 5.2.1 beta 2 for the Apple Watch. No changes have been discovered in this update quite yet, but that could change with future releases.
