solo-1.5.3

Replace B# tone with A# to avoid affecting IMU3

solo-1.5.2

• increased assumed current usage during RTL for energy based failsafe (#282)

solo-1.5.1

diff from 1.5.0:

• added distance-based battery failsafe logic

solo-1.5.0

diff from 1.4.10:

• fixed a bug where an incomplete compass cal would lock up subsequent attempts
• fixed a bug where an EKF or GPS glitch failsafe recovery could override a battery failsafe
• report PreArm: OK or Arm:OK in STATUSTEXT at regular intervals
• don't run the GPS detection logic repeatedly if the GPS_UBLOX_NO_FIX parameter is set

solo-1.4.10

diff from 1.4.9:

• ensures that all modes that utilize the land controller's method get_land_descent_speed() call init_land() prior to set all land ramp variables correctly
• constrains the output of the landing ramp between the min and max land speeds (as set in params)

solo-1.4.9

diff from 1.4.8:

• ensures that in-air mag field and yaw state flags are reset upon landing which addresses poor mag performance while taking off and landing multiple times in a magnetically anomalous environment

solo-1.4.8

diff from 1.4.7:

• increase min pwm output when thrust a priority to prevent uncontrolled descents
• added a 3s latch to prevent localised magnetic anomaly from failing pre-arm checks

solo-1.4.7

diff from 1.4.6:

• added pre-arm check that disables flight under a certain air pressure (altitude check)
• enforce gimbal in NEUTRAL mode during level and compass calibrations

solo-1.4.6

diff from 1.4.5:

• improved land detector to help prevent tipovers
• fixed a failsafe in which GPS is regained but not recovered (still glitching)

solo-1.4.5

diff from 1.4.4:

• clearing a magnetic anomaly will latch and prevent the magnetic anomaly from blocking takeoff
• resolved a failsafe condition where GPS was regained before a GPS glitch recovered
