ArduPlane 2.40 has now been released. Many thanks to everyone who gave flight test feedback on the beta release!
Note that ArduPlane now uses MAVLink 1.0, so you'll need to update your Mission Planner to the newer version, which supports that. You'll find it in the same directory as your current Mission Planner, in a file called ArduPilotMegaPlanner10.exe

- switch to MAVLink 1.0 for telemetry. This has been pending for quite some time, and it is nice to finally get it done. The reason it took so long is we needed some coordination between the various bits of code that deal with MAVLink in APM (the ground stations, autotest, ArduPlane itself etc). The various pieces finally came together and we can now support MAVLink 1.0 properly. This doesn't change the features of APM significantly, but it does prepare us for telemetry improvements in the future.
- auto-configuration of UBlox GPSes. It should now be possible to attach a UBlox GPS in just about any state and the APM GPS code will re-configure it appropriately. The configuration isn't saved, so if you power cycle the GPS it will revert to what was set before, but it should now be possible for the APM to use a UBlox in factory default config. It's still a good idea to setup your UBlox correctly (38400 baud in UBX binary mode) as that will make the detection faster on startup, but it should work regardless.
- updated Camera and Mount control code from Amilcar Lucus and Greg Fletcher. These are not enabled by default, and I have not tested them myself, so I'm hoping Amilcar and Greg will be able to answer any questions that come up. Many thanks to Amilcar and Greg for all their work on this!
- sped up eeprom erase using chip erase
- Added ARSPD_USE parameter. This is useful when first setting up an airspeed sensor. The existing ARSPD_ENABLE parameter only allowed you to enable/disable airspeed and if enabled then it would be used for flight control. With ARSPD_USE you can now enable the airspeed sensor but not ask APM to use it for flight control (by setting ARSPD_ENABLE to 1 and ARSPD_USE to 0). That allows you to log your airspeed data without using it for flight control, which means you can validate the airspeed sensor is working correctly without risking your airframe if it is badly calibrated.
- fixed an ELEVON_REVERSE bug. The ELEVON_REVERSE parameter was being applied to only one channel, whereas it should be applied to both channels. If you use elevons then please be careful to carefully test your setup before your next flight!
