Apple doesn’t work what their operating system is concerned, since they left new betas (the first) of iOS 10.3.2 watchOS 3.2.2 and tvOS 10.2.1. Just yesterday they left the final versions of iOS 10.3, macOS 10.12.4, watchOS 3.2 and 10.2 tvOS with some interesting new features and bug fixes. Probably, we have new updates coming to correct details and possible errors of the versions mentioned above. “
Apple keeps and releases new versions beta, iOS 10.3.2, macOS 10.12.5, watchOS 3.2.2 and tvOS 10.2.1
the funny thing is that Apple skips a number, i.e., instead of being in the case of iOS (10.3.1) and watchOS (3.2.1) are official 10.3.2 and 3.2.2. is something that few occasions you get to observe, the last time took place by a bug in the Apple Watch (watchOS 3.1.1) and instead became watchOS 3.1.3.
to be very recent betas, public versions (in the current case of iOS 10.3.2) are not available since they are released first Developer so that they themselves can make the first tests on devices, including watchOS and tvOS departing only to developers.
another reason why Apple might skip a version is that they are planning major improvements in performance. When Apple releases a version of emergency or for safety, there are no betas from one day to another. So possibly this version serves to improve the performance of our devices.
in the case of macOS, are facing a new version as they are planned during the calendar year of the operating system. They come to exist from 5 up to 7 updates from the official start. In the former case, OS X El Capitan came to have up to 6 versions. Most to correct errors in performance in many Mac.
are awaiting possible Visual innovations that can bring any of these betas remember that you can only download them if they are registered in the Apple Developer Center developer.
