I suppose they are bug fixes within the initial software, in rare cases what they saw was the antenna analyzer, but only if the equipment did not have it installed, which today is unlikely, it was only in the first units manufactured for that purpose, 2015 I guess.
I had the original software, from 2016 and when I uploaded it, it appeared with a date of 2017, it corrected a strange noise when I pressed the PTT but over time it appeared again, it must be a hardware problem or something in the microphone.
