Two weeks after making the first available, Apple today released the second test versions of iOS 10.3.3 (build 14G5037b), from macOS Sierra 10.12.6 (16G12b), from watchOS 3.2.3 (14V5734a) and the tvOS 10.2.2 (14W5735a) for users of iPhones / iPads, Macs, Apple Watches and Apple TVs.
As we said, we are getting closer to the Worldwide Developers Conference (WWDC) 2017 and, consequently, to know iOS 11, macOS 10.13 (or 11?), WatchOS 4 and tvOS 11. Therefore, it is quite possible that the novelties even those smaller and almost imperceptible remain even for these future versions.
In other words, just wait for that good cleaning (bug fixes and general improvements) for these new beta versions that have everything to be the last ones that we will see coming out next Monday (6/6).
Very soon, iOS 10.3.3 beta 2 and macOS Sierra 10.12.6 beta 2 will also be available to members of the Apple Beta Software Program. If you participate in the tests, stay tuned!
