After launching a revised version of the previous beta about a week ago, Apple released the beta 4 versions of iOS 13, iPadOS and tvOS 13 for the developer community. If you are part of it, you can already update from previous betas as if they were stable versions.
Beta 4 for iOS 13, iPadOS and tvOS 13
Hopefully after the release of this beta 4, Apple also launch a new version of the public betas so that general users who dare can anticipate the official launch of all these systems (which presumably be at the end of September). It can happen at any time.
It is also likely that, as soon as a few days pass, the developers will find new details about the news by scrutinizing the source code of this beta. Another thing we have to remember again is that We advise against the installation of these betas (even the public) if you're not completely sure of what you do. They are unstable systems with errors that can affect the behavior of your device. It is best to wait for the holidays to end and thus enjoy the stable launch.
