Dan Pražák Apple released the fourth betas of iOS 12.3, watchOS 5.2.1, tvOS 12.3, and macOS 10.14.5 to registered developers this evening. Together with them, he also made public beta versions (with the exception of watchOS) available for testers.
New betas can be downloaded via Settings on your device. You must have the appropriate profile added for installation. Systems can also be obtained in Developer Center on Apple's official website. Public testers can then use the site beta.apple.com.
The fourth beta contains only fixes for specific bugs that plagued the previous version, and thus basically does not bring any significant improvements. The only news is a previously undiscovered pop-up window for easy attachment of accessories that appeared when the iPhone was brought close to the camera, and which suggests that iOS 12.3 could make some NFC functions available.
However, previous beta versions were richer in news. Especially the first betas, which in the case of iOS 12.3 and tvOS 12.3 brought the new Apple TV application.
