Copter-3.5.0-rc5 has been released for beta testing and includes fairly major enhancements and bug fixes over -rc4. The list of changes can be found in the ReleaseNotes and it's also copied below:
Changes from 3.5-rc4
1. Intel Aero RTF support
2. Smart battery fetches serial number, temperature and individual cell voltages
3. Vehicle heads towards target point instead of next waypoint during straight line waypoint mission commands in AUTO
4. Visual Odometry supported using VISION_POSITION_DELTA mavlink message
5. Do-Set-Home sets EKF origin allowing user to specify vehicle starting position without GPS
6. Object avoidance parameter (AVOID_MARGIN) allows configuring distance to maintain from objects
7. Motor output can be duplicated to multiple channels
8. IRLock can be connected to any I2C bus
9. Piksi "Multi" GPS support
10. Performance Improvements:
a) inter-EKF scheduling cooperation (improves load balancing when using multiple EKFs)
b) parameter requests from GCS processed asynchronously (resolves bad flight behaviour when fetching params in-flight)
c) display performance improvements
11. Bug fixes including:
a) LSM303D (Pixhawk's backup IMU) timing fixes
b) auxiliary PWM outputs update even when RC input stops
c) dataflash log over mavlink fixes
d) EKF recovery from severe errors
e) reduce twitch when transitioning from spline to straight line waypoints in AUTO
f) enable motors after initialisation completes (resolves some BLHeli ESC initialisation and calibration issues)In case you're wondering why so much is included in this release candidate, it's mostly because of 10b ("Performance Improvements for parameter requests from GCS...") and 11a ("LSM303D timing fixes"). These important changes require at least a few weeks of beta testing and we felt back-porting these changes on top of -rc4 was actually more dangerous/error-prone than making AC3.5-rc5 use all our latest code. Good news is that there's a lot of improvements, bad news is a few new issues will likely appear.
So thanks for your patience and again, thanks very much for beta testing this release!
