Apple today released second betas for the upcoming iOS 12.3, tvOS 12.3, macOS Mojave 10.14.5 and watchOS 5.2.1 software updates, arriving less than two weeks after the first betas were made available to the company’s registered developers and public beta testers.

Public betas matching today’s developer-only software should drop shortly. Apple’s official release notes only mention bug fixes and unspecified improvements.

The over-the-air updates can be downloaded and installed through Apple’s Software Update mechanism provided your device is running a special configuration profile which can be obtained for your device through the company’s Development Center portal.

iOS 12.3 and tvOS 12.3 include an overhauled TV app with Channels

The inaugural developer beta of iOS 12.3 brought out a redesigned Apple TV Remote widget in Control Center (now in full screen), support for more transactions in the Wallet app as well as early platform support for Apple Card (which pairs in a similar fashion to AirPods).

iOS 12.3 also brings Apple’s overhauled TV app that we recently went hands-on with. It’s now easier to navigate, supports more content sources and lets you subscribe to individual channels like Starz or HBO, as well as stream them, without having to download any apps at all.

The Channels feature is basically an a la carte offering that lets you pay for individual apps/channels without the need for a cable/satellite subscription. The new TV app is available in both iOS 12.3 and tvOS 12.3. Come this fall, Apple will also release a standalone TV app for macOS as the tech giant gears up to launch its new video-streaming service, Apple TV+.

We’ll update this story as more information about any noteworthy changes in the new betas becomes available. And as always, if you spot something noteworthy in the new betas that we haven’t mentioned yet, be sure to tell us about it in the comments.
