At the end of the afternoon yesterday we got the news about the last of the beta versions that remained to be released for the developers. The watchOS 5 beta 4.3 is also available to developers and with it the circle of beta versions closes this week.
Hours before the versions were released macOS, iOS and tvOS beta. When it seemed that they would leave it for the next day (Apple already did it on some other occasion), the new beta version appeared with the typical bug fixes, stability improvements and watchOS performance.
So we already have all the beta versions for developers released and with that we improve some details of the system's own functionality in this case, such as the bedside mode or the clock interface while charging. In any case, the Apple Watch and especially the latest versions of it work wonderfully in terms of the fluidity of the system, battery and agility in opening the applications that we have installed, etc.
As we always warn about these beta versions for the Apple Watch, the best thing to stay out of to avoid problems is that in the Apple smartwatch there are no options to install a previous version once you update either beta or final version. In this sense, any error could be fatal for the user, leaving the device unusable, so the recommendation as always is stay out of these beta versions and let the developers test them and let us know your news. For the Apple Watch there are no public beta versions for users.
