Apple has released iOS 14.2 beta 4 for developers. The update is available over-the-air for users who already had a previous beta installed, and via Apple Developer Center for registered users.

iOS 14.2 beta 4 has been released just a week after beta 3 was released to developers, and on the same day as the final version of iOS 14.1 was released to everyone.
