L1 Firmware Update: What's New

The key features of the L1 firmware update are:

Added Zenmuse L1 calibration, allowing users to make a calibration file to complete L1 calibration and restore factory settings.
Added Elevation Optimisation to Mapping Flight. The L1 only takes photos and does not record point clouds during elevation optimisation segments of flight when Elevation Optimisation is enabled.
The default metering for photos during flight route is updated to center-weighted average metering.
The L1 camera will automatically focus to infinity after the focus mode switched to MF.
The Calibration Flight is updated to acceleration and deceleration calibration flight (except for Linear Flight Mission). The aircraft will fly forward 30 m (98 ft) and then fly backward 30 m (98 ft) at next nearest waypoint after every 100s during Waypoint flight when the calibration flight conditions are met.
The aircraft will also perform a calibration at intervals of less than 100 seconds during extended flights using Mapping flight.
Fixed issue: Incorrect flight height displayed during Terrain Follow Flight.
Fixed some minor bugs.
