If using Android then look at DJI GO in play store, it tells you the changes there. Likewise with App' Store for IOS devices, in fact IOS shows a detailed history for all versions to date.
Plus they have changed some stuff with respect to waypoints...You need waypoints closer together or it will not load into the drone. You use to be able to set your limits to the distance you wanted or unlimited, they have taken that away...They don't tell you when they are taking features away, you find out by using.
Spot on. !! That's why I'm still on GoVer 2.4.3. My P3 is flying perfectly on it. I don't intend to Downgrade to a more recent version. Why fix something that is not broken.
