This week, after a special event in which we met new Apple services (Apple News +, Apple Arcade and Apple TV +) besides the Apple Card, the company released the final versions of iOS 12.2, tvOS 12.2 and macOS Mojave 10.14.4; now, a few days later, she made available the first beta versions of iOS 12.3 (compilation 16F5117h) and the tvOS 12.3 (16M5117f), which feature the new Apple TV app.
Interestingly, the company also released the Apple TV Software 7.3 beta (build 12H825), name of the system that runs on the third generation Apple TV. Most likely this compilation has to do with the availability of the TV + service for the device after all, it makes perfect sense for Ma to put their new service on as many devices as possible.
These new versions of iOS and tvOS should be painting very soon in the Apple Beta Software Program. And rest assured: if more news comes, we'll inform you here. 😉

In fact, the new Apple TV app was also taken to third generation Apple TVs. This means that they will most likely also receive the Apple TV + service in the future.

A few hours later, the first beta version of macOS Mojave 10.14.5 (compilation 18F96h). Any significant news, we will notify here on the site.
Update III, by Rafael Fischmann 3/28/2019 s 14:15
A day later, now it was the turn of watchOS 5.2.1 beta (build 16U5079d) to exit. By the version number, it will be a very timely update even for Apple Watches.
Systems released yesterday are also already in the Apple Beta Software Program.
