Does anyone have a list of what SW revisions have what features?  When did “orbit” get implemented?  I have 2.4.3 and don’t seem to have it or other features my friend, who has 3.1.3 has.  I have heard that DJI doesn't do a very good job explaining what an update does, but does anyone have a list of what SW version has what?

i'm not sure about the whol elist, but those  Intelligent Flight Modes were intruduced in firmware V1.4.10 for pro/adv and V1.1.30 for standard. You must be on iOSV2.2.0 and Android V2.1.0 of DJI go to use them. Here's hoping the community can help list out various features/changes included, as the DJI changelogs are not always great.

most everyone has 3.1.3 on Android cuz they forced the update
