1.9.0 Release notes

Please read the release notes carefully and upgrade INAV Configurator application.

INAV is and will remain open-source and free, but you are more than welcome to support the development.

This release was supported by our awesome sponsors CarbonBird.com, Airbot, ADPM Drones and a number of supporters on Patreon.

CLI parameter renaming / new parameters

New parameters have been introduced. Some CLI parameters were renamed to support new features or to better reflect their meaning:

Name	Description
rangefinder_median_filter
baro_median_filter
failsafe_lights	Enable or disable the lights when the FAILSAFE flight mode is enabled. The target needs to be compiled with USE_LIGHTS [ON/OFF]. Default is ON
failsafe_lights_flash_period	Time in milliseconds between two flashes when failsafe_lights is ON and FAILSAFE flight mode is enabled [40-65535]. Default is 1000ms.
failsafe_lights_flash_on_time	Flash lights ON time in milliseconds when failsafe_lights is ON and FAILSAFE flight mode is enabled. [20-65535]. Default is 100ms.
battery_capacity	Set the battery capacity in mAh or mWh (see battery_capacity_unit). Used to calculate the remaining battery capacity. Default is 0
battery_capacity_warning	If the remaining battery capacity goes below this threshold the beeper will emit short beeps and the relevant OSD items will blink. Default is 0
battery_capacity_critical	If the remaining battery capacity goes below this threshold the battery is considered empty and the beeper will emit long beeps. Default is 0
battery_capacity_unit	Unit used for battery_capacity, battery_capacity_warning and battery_capacity_critical [MAH/MWH] (milliAmpere hour / milliWatt hour). Default is MAH
manual_rc_expo	Expo settings used for the PITCH/ROLL axes by the MANUAL flight mode [0-100]. Default is 70
manual_rc_yaw_expo	Expo settings used for the YAW axis by the MANUAL flight mode. Default is 20
manual_pitch_rate	Servo travel multiplier for the PITCH axis in MANUAL flight mode [0-100]%. Default is 100%
manual_roll_rate	Servo travel multiplier for the ROLL axis in MANUAL flight mode [0-100]%. Default is 100%
manual_yaw_rate	Servo travel multiplier for the ROLL axis in MANUAL flight mode [0-100]%. Default is 100%
gps_ublox_use_galileo	Enable use of Galileo satellites. This is at the expense of other regional constellations, so benefit may also be regional. Requires M8N and Ublox firmware 3.x (or later) [OFF/ON]. Default is OFF
smartport_fuel_unit	Unit of the value sent with the FUEL ID through the S.Port telemetry [PERCENT/MAH/MWH]. Default is PERCENT
osd_stats_energy_unit	Unit used for the drawn energy in the OSD stats [MAH/WH] (milliAmpere hour/ Watt hour]. Default is MAH
osd_main_voltage_decimals	Number of decimals for the battery voltages displayed in the OSD [1-2]. Default is 1
osd_wh_drawn_pos
osd_bat_remaining_capacity_pos
osd_bat_remaining_percent_pos
osd_efficiency_mah_pos
osd_efficiency_wh_pos
display_force_sw_blink
mag_to_use	Allow to chose between built-in and external compass sensor if they are connected to separate buses. Currently only for REVO target
nav_fw_launch_min_time	Allow launch mode to execute at least this time (ms) and ignore stick movements [0-60000]. Default is 0
nav_fw_launch_max_altitude	Altitude (centimeters) at which LAUNCH mode will be turned off and regular flight mode will take over [0-60000]. Default is 0
