Copter 3.5-rc1 28-Jan-2017
Changes from 3.4.4
1) Multicopter firmware consolidated into single binary, users must set FRAME_CLASS parameter (1:Quad, 2:Hexa, 3:Octa, 4:OctaQuad, 5:Y6, 7:Tri)
2) PixRacer specific items:
a) board LEDs supported
b) ESC calibration start problem resolved (was sometimes not detecting high throttle from pilot)
3) Relaxed compass calibration and compass consistency checks
4) Sensor and Optional Hardware Improvements:
a) IMU sampling rate for MPU9250, ICM20608 IMUs to 8kHz for improved vibration resistance (Pixracer, Pixhawk2)
b) Onboard Display (http://ardupilot.org/copter/docs/common-display-onboard.html)
c) Here+ RTK GPS (UBlox M8P RTK) support
d) LightWare I2C drivers usable on Copter (thanks to in-tree drivers below)
e) MaxBotix sonar with serial interface now supported
f) Bebop optical flow (but sonar not yet operational making this feature currently impossible to use)
5) Precision Loiter using IRLock sensor (set CH7_OPT to 39)
6) Delivery improvements:
a) Servo gripper (http://ardupilot.org/copter/docs/common-gripper-servo.html)
b) Package_Place mission command (drops package without vehicle landing)
7) Pozyx support for Non-GPS flight (http://ardupilot.org/copter/docs/common-pozyx.html)
8) EKF improvements:
a) improved blending of optical flow and GPS
b) EKF3 added in ride-along. Enable by setting EK3_ENABLE=1
c) improvements when using range finder as primary height reference
9) Object Avoidance improvements (http://ardupilot.org/dev/docs/code-overview-object-avoidance.html):
a) uses mini-fence
b) accepts MAVLink distance-sensor messages
c) simple avoidance in AltHold mode
10) Other improvements:
a) pre-arm check that logging is working
b) better reporting of battery failsafe to ground stations
c) reduced minimum waypoint speed to 20cm/s
d) Flight time recorder (http://ardupilot.org/copter/docs/common-flight-time-recorder.html)
e) UBlox GPS baud rate fix (was occasionally selecting wrong rate)
11) Technical improvements (users may not see a functional change):
a) in-tree drivers lead to improved sharing of drivers with Linux boards
b) copter arming checks consolidated with other vehicles

Hi, die RC 2 ist draußen:

Copter 3.5-rc2 13-Mar-2017
Changes from 3.5-rc1
1) Improved dual GPS support including blending (set GPS_TYPE2=1, GPS_AUTO_SWITCH=2)
2) AutoTune with position hold (enter AutoTune from Loiter or PosHold modes to enable light position hold)
3) New boards/drivers:
a) PixhawkMini support
b) AUAV2.1 board support (for AUAV2.1 set BRD_TYPE to 20 to distinguish from PixhawkMini)
c) Garmin LidarLiteV3 support
d) Maxell Smart Battery support
e) Invensense ICM-20602 IMU and ST L3GD20H gyro drivers added
4) IMU to Motor lag reduced by 0.6ms
5) Object Avoidance:
a) support TeraRanger Tower sensor
b) support using normal (1-dimensional lidar/sonar)
6) Minor changes/enhancements:
a) add MOT_SPOOL_TIME parameter to allow users to control spool-up time of motors
b) remove Solo gimbal from -v2 because of 1MB Flash limit on many Pixhawk1s
c) altitude check for Guided mode takeoff (must be at least 1m)
d) auxiliary switch to arm/disarm vehicle (set CH7_OPT to 41)
e) change battery alarm tone to reduce impact on IMU
f) add battery monitor health reporting
g) support DO-FENCE-ENABLE mission command to enable/disable fence during missions
7) Bug Fixes:
a) OLED Display clears messages after 10seconds
b) Servo Gimbal output range fix (could attempt to push servos beyond their limits)
c) fix do-set-servo
d) fix dataflash log time (was always appearing as 1970)

Zufällig gesehen, die RC 4 ist schon raus:

Copter 3.5-rc4 08-Apr-2017
Changes from 3.5-rc3
1) Bug fixes including:
a) Baro based altitude estimate fixes including limiting ground temperature to reasonable value
b) Fix 0.6ms lag reduction
c) Fix Invensense IMU driver temperature reading
d) Fix semaphore take during interrupts that may have caused very occasional main loop rate issues
e) Return Home if GCS asks for first (i.e. zero-ith) mission command (required for Solo)
