We are continuing with the "minor" updates for most users, and tvOS developers now have the tvOS 4 beta 9.2.2 with the solution to the small errors of the system and improvements in the stability of the same.
The truth is that we do not have major changes in these new tvOS betas as has happened with the OS X 10.11.6 El Capitan beta and it seems that it will be until the new versions arrive after the summer. At the moment what we have are updates that offer stability to the system.
This fourth beta is available for developers and also for users enrolled in the public beta program and taking into account the few improvements they provide, the best thing is that if we are in a beta or stable version and we do not have problems of any kind. better to stay on the sidelines. Normally, before the final version of an Apple operating system, the GM version (Golden Master) was launched but that hardly happens and We are not clear when Apple will stop releasing betas until they release the official version.
Beta versions are always unstable versions despite the fact that most of the functions and applications work normally. In this case, the beta of tvOS and the next version of the operating system of Apple's set-top box do not have great differences and surely that all users or most of them can wait for the official version that will come in September together with that of iOS and the new iPhone. Less is missing.
