Hello.. In typical DJI fashion regarding their lack of proper documentation and change logs. There are at least two new restrictions / changes that are not documented or mentioned in the 1.4 firmware update that some of you may be interested in knowing about. First one is new no fly zones, which were likely the result of the 3DR Solo that crashed in the middle of a US Open Tennis game and was highly televised. You can no longer fly near most stadiums among other things. If you were also interested in filming around places like flushing meadow park you will have a hard time now as most of it is now blocked off with these additional no fly zones added. Second for those of you who need to fly over 500M / 1640 feet high. The ability to fly higher using the Return to Home function followed by throttle up no longer works. You can not go past 1640 feet any longer using that trick / glitch / function or whatever you would like to call it. If there are any other restrictions that were added to the new firmware you know about, feel free to add them to the thread.
