@Arne-W Glad to see some activity on this GCS
However, the ArduPilot firmware server is way out of date for versions of this
We need either to arrive at a procedure to keep the firmware server up to date or remove APMPlanner software from that server and point the wiki to the Github release page
Can you attend either the next DEVCALL or EURO DEVCALL to discuss?
you can also contact me or Tridge or Randy on Discord
thanks
