Changes:
Fix a crash introduced in 2020.3.10
Improve error message when no aircraft search paths are available
Fix a crash with misconfigured traffic taxi routes
Update AI traffic schedules
Usability
Flightplan loading within the launcher.
Chinese, Russian and Italian translations for the launcher and UI
Improved support for the state of the aircraft depending on starting location - cold and dark on the ramp, engine running ready for take-off on the runway, or in cruise flight.
Input
Improved joystick configuration and binding options.
AI / Multiplayer
Multiple Levels of Detail (LoD) for MP and AI aircraft. To improve performance, low-detail models are used when the viewer is far from the MP aircraft.
Fallback models to display in the case where a viewer does not have the MP aircraft installed.
Many improvements to AI models including new liveries, timetabled movements
Graphics
Support for retrieving Canvas images over HTTP. This is a useful feature for displaying instruments like a PFD, ND, EICAS or any MFD externally from the FlightGear 3D main window in a separate window or on a separate monitor, computer or a mobile device. See Read_canvas_image_by_HTTP for more information.
Improved cloud rendering with stronger Mie scattering on cloud fringes, improved scattering on cirrus clouds
Reset: wipe the Effect UniformCache
Scenery
Improved scenery for Hawaii, the default location for this release.
New scenery for Jan Mayen, situated northeast of Iceland. Including the active volcano of Beerenberg (2277m).
JSBSim
The feature fail_hardover of the <actuator> component was not giving the correct output in some occurences when clipmax was smaller in absolute value than clipmin.
Tables CORNERING_COEFF could not be used for BOGEY contact points.
Bug fixes for JSBSim atmosphere model at very high altitudes
Fixed PID integration with the 3rd order Adams-Bashforth was inccorect.
The fail_stuck property of sensors (accelerometers, magnetometers, gyro, etc.) without a <lag> element was setting the output to zero instead of sticking to the last output value.
When a sensor was stuck, the drift, gain, bias and quantization of the last output before being stuck were ignored.
Fixed the Calibrated Air Speed (CAS) computations for supersonic velocities
Fixed the Nlf (Normal load factor) sign
Nlf can now be specified as an initial condition via the property ic/targetNlf
Added blocking sockets to the input features
Added a property to piston engines to get the AFR (Air to Fuel Ratio)
Added conversion from m/s to ft/s
Restored the initial conditions for engines running (-1 means all engines)
Significant Aircraft Updates
"Metadata" has been added to many aircraft, making it easier to find new exciting aircraft to fly using the launcher, whether you are interested in aircraft from the 1920s or twin engined business jets.
