------------------------------------------------------------------
Copter 3.4.0-rc3 31-Aug-2016
Changes from 3.4.0-rc2
1) Landing detector improvements:
a) checks that descent rate is less than 1m/s (avoids disarms when vehicle is obviously still descending)
b) tradheli fix for landing detector
2) WP_NAVALT_MIN parameter limits maximum lean angle when vehicle is below the specified alt while taking off or landing. Only applies in LAND mode, final stage of RTL and during take-off in AUTO mode
3) GND_EFFECT_COMP parameter allows turning on EKF compensation for ground effect during take-off and landing
4) Advanced Failsafe for use in OutBack challenge (see http://ardupilot.org/plane/docs/advanced-failsafe-configuration.html)
5) AutoTune minor improvement to reduce step size on vehicles with very low hover throttle (i.e. high power-to-weight ratio)
6) Bug fixes, minor improvement:
a) LAND_SPEED_HIGH allows specifying vertical descent speed separate from WPNAV_SPEED_DN during the initial descent in LAND mode (and final stage of RTL)
b) improved USB driver reliability for windows users (NuttX change)
c) report dataflash logging health to ground station
d) Guided mode accepts yaw rate from SET_ATTITUDE_TARGET message
