Apple on Monday released the third betas of iOS 12.3, tvOS 12.3, watchOS 5.2.1 and macOS 10.14.5 to developers. Registered developers can install the updates via each platform’s respective OTA mechanisms, or through Apple’s Dev Center.

As we’ve mentioned in our previous beta posts, iOS 12.3 and tvOS 12.3 both include Apple’s new TV app. The app, unveiled at last month’s media event, features a more streamlined user interface and offers support for more streaming services.

The betas also bring about support for Channels, an a la carte plan that allows users to pay for individual streaming apps without needing a cable/satellite subscription. Bug fixes and under-the-hood improvements round out the updates.

As usual, we’re installing today’s betas and will be sure to report back if we discover anything new worth noting. And of course if you spot something significant we haven’t mentioned yet, be sure to tell us about it in the comments below!
