I want to get more into autonomus flight with my RC plane and I also have some old stuff to make a drone as well. I already have 2 old APM 2.8 boards and I would like to use those and I was wondering what versians of ardupilot and arducopter to get for them. The official website says 3.3.0 is the last one but 3.4.0 is the oldest version of arduplane on the downloads site and I have been seeing that they are the same so what do I get?
