No idea what it did but see nothing differant and use this pad for here when to lazy and sit at my desk on mac and to fly with. As far as reading in those blogs or whatever you call them I don’t. I have to see for myself. Like software and firmware updates.
Don’t mind being the guinea pig.
I’ve done dozens of flights with 13.3.1 and am now on 13.4 (beta). No problems with either of them. Can’t speak for older hardware - I upgrade my phone every 4 years so I’m on a new 11 pro (which I’ll have until 2023 or 24).
The only problem I’ve ever had with iOS updates was running an early beta of 13.0 over the summer. Lesson learned - not a good idea to use an initial beta of a new OS for anything critical: it overheated and crashed repeatedly with Go4. Later betas fixed the problem.
