This roadmap shows the direction of the ArduPilot team in 2019 and beyond. The purpose is not to guarantee exactly when features will be added but instead to help the team, Partners and anyone else working on ArduPilot to spot areas where we can cooperate. There will certainly be many developments that are not on this list.
Each section of the roadmap has the name of the core developer in charge so feel free to contact them if you’re looking to help out. Also if you’re a developer and would like to add some items please PM me on discuss. I’m “rmackay9” on most platforms.
