And it was the only beta version that was missing to complete the different versions of Apple software, in this case the watchOS 1 beta 4.3 has build 15T5165e and in principle we do not have many details of the novelties that it implements. What is certain is that improvements are added to the stability of the system, improvements to its security.
Actually the improvements implemented in these first betas are outstanding beyond the improvements in aspects directly related to the soft. It is possible that as the hours pass and more develop, they will try it start to find improvements and news.
And it is that in iOS and macOS and tvOS we saw some important news and different improvements are still being discovered such as the podcast application or the code that refers to a new iPad Pro with Face ID. In short, we have to wait for the developers to start investigating this beta version as they did with the rest of the versions released yesterday afternoon.
The beta versions for developers are always better to look at from afar and in the case of the Apple Watch, more. And it is that installing one of these beta versions on the Apple smart watch means not being able to go down to the previous version and in case of problem it is necessary to stick with it until the next beta. The Apple Watch does not allow downgrades, so the best thing is read the news that the developers give us about the news and wait for the final version for everyone.
