This is not a routine patch. The release combines new fixed-wing navigation modes, terrain-relative altitude support, DroneCAN, expanded MAVLink, VTOL transition logic, new sensors and new flight-controller targets with configuration changes that affect the upgrade path.
For an upgrade from 9.x, INAV explicitly says to use Configurator's Firmware Flasher Backup Config and Restore Config path, flash with Full Chip Erase, then restore through Configurator so settings migration runs. Pasting a CLI diff all directly does not invoke the migration. Bench-check sensors, outputs, failsafes and navigation settings before fitting props or flying.
