Testing of iOS and other Apple operating systems continues with the California giant launch last night of a series of beta news for iOS 14.4, iPadOS 14.4, macOS 11.2, tvOS 14.4, and watchOS 7.3. The first beta of these OS dates from December 16, 2020, the second, from January 14.
For the moment, this is the release of the Release Candidate version for each of these OS, ie theoretically the last test version before publication of the Golden Master version, normally identical to the final version. We can thus wait for the final versions of iOS 14 and iPad 14.4, macOS 11.2, tvOS 14.4 and watchOS 7.3 for next week.
See here the complete list of new features that iOS and iPadOS 14.4 should introduce. For watchOS 7.3, macOS 11.2 and tvOS 14.4, there would be no major changes to report, apart from a new “Unity” watch face for Apple Watch.
