Apple has already released a beta of iOS 14.2, making it available to developers just one day after the public release of iOS 14 and then to public testers just a few days later. In addition to iOS and iPadOS 14.2, Apple made beta versions of tvOS 14.2 and watchOS 7.1 available.
It appears that iOS 14.1, which Apple appeared to skip past in releasing the 14.2 beta, is intended to support the features of the new iPhone 12. It was released to the public with no public beta test.
