In this case Apple released all the versions available for all OS and developers can now begin to test whether the bug fixes and improvements in system stability are effective in these new beta .. We are facing the second beta version of iOS 10.3.3, tvOS 10.2.2, watchOS 3.2.3 and the previously released beta 2 of macOS Sierra 10.12.6, so we are clear that Apple continues to work hard on the following versions and will leave the current ones as polished as possible to focus on the improvements of the following macOS 10.13, iOS 11, watchOS 4, and tvOS 11.
What's new in these developer betas is intended for stability and Except the wallpapers they added in iOS 10.3.3 beta 1 a couple of weeks ago, the rest changed little or nothing. The truth is that the current versions and the beta ones are really stable, they do not seem to have problems with the current devices but they have to correct them as much as possible so as not to have to update again in the future.
Now the new versions for Apple Watch, Apple TV fourth generation and iOS devices add fixes and stability to the system, something that we usually see every week and that we appreciate. Yes, for us the improvements in the functions are just as important as in the stability of the system and in this sense we can be happy with the versions that we have that show few errors and those that appear correct them in the betas. Obviously they can always be improved, but the truth is that all devices work very well with each of their versions.
Now we have to wait and see the news of the next versions that will be shown at WWDC on June 5. The rumors about the news have not transpired so everything new will be a surprise.
