Apple has issued Release Candidate versions of iOS 14.4, iPadOS 14.4, macOS Big Sur 11.2, tvOS 14.4, and watchOS 7.3 to users who are involved in the beta testing programs.
Both developer beta and public beta testers can now access the release candidate builds of the various operating systems. A release candidate typically indicates a final version is coming soon, which would be available to the general public.
None of the new system software versions are expecting major new features, and instead will likely focus on bug fixes, minor improvements, and small enhancements and changes to the various Apple operating systems. There are a few small new features included in iOS 14.4 related to Homepods, for example.
