Warning #1: PX4/Pixhawk users upgrading from AC3.1.5 (or earlier) may need to re-do their compass and accelerometer calibration because AC3.2 also uses the backup compass and accels. Pre-arm checks have been added to ensure this has been done.
Warning #2: on the APM2.x the logs must be downloaded using MAVlink instead of the terminal.
AC3.2-rc14 is now available for BetaTesters through the mission planner’s Beta Firmwares link. The full release notes can be found in ReleaseNotes.txt and changes from -rc13 can be seen below.
Feel free to raise issues found during testing on this discussion or in the new support section in the APM Forum.
It’s a big release with “the onion” restructure and a bunch of new features (including these 57 closed items) so we need to re-test almost everything including all flight modes, all mission commands and all the new features. Marco and I will be maintaining (and adding to) this testing list. Issues reported will first be checked by Jonathan, Marco and I and then confirmed bugs/issues will be put on the github issues list (and then hopefully fixed).
Thanks especially to the beta testers who put their copters at risk testing each release. Enjoy!
Changes from 3.2-rc13
1) Safety Features:
a) fail to arm if second gyro calibration fails (can be disabled with ARMING_CHECK)
2) Bug fixes:
a) DCM-check to require one continuous second of bad heading before triggering LAND
b) I2C bug that could lead to Pixhawk freezing up if I2C bus is noisy
c) reset DCM and EKF gyro bias estimates after gyro calibration (DCM heading could drift after takeoff due to sudden change in gyro values)
d) use primary GPS for LED status (instead of always using first GPS)

Henri,
I've just tested and I'm correctly seeing the "Arm: Safety Switch" message when the safety switch is not pressed but it also arms correctly when the safety switch is pressed (i.e. not blinking). I'm using MP 1.3.9.1 build 1.1.5350.14145 which is the latest beta release.
I guess this is different to what you're seeing or maybe I'm misunderstanding the issue?
Thank you for answering Randy.
I didn't fully understand Andrew Nicholas's query:
"Every time i load the latest Beta 3.2-rc1 on Pixhawk i get a pre flight check gps not calibrated from apm"
Hi dev team and testers,
Tested version 3.2 RC5 on APM 2.6 and Pixhawk. Works very well except in a fast descend, straight down, in Drift mode my Tarot 650 almost became unstable. I have not noticed this behaviour in PosHold. This video shows a test of Follow Me and PosHold.
Is 3.2 released?
I see you have started with 3.3
"Author: Randy Mackay <rmackay9@yahoo.com> Date: Mon Aug 18 12:56:22 2014 +0900 Copter: range check ACRO_EXPO to be no more than 1 APMVERSION: ArduCopter V3.3-dev"
Goran,
No, we've branched though so that we can limit any further changes getting into AC3.2. Our release procedures are documented here by the way although it's a bit technical.
All my tests with Pixhawk and APM Copter are done with Futaba R7008SB (SBUS2 pin) without the external encoder.
But still I advise you to set your rx in SBUS1 mode over CH8 output (SBUS) and connect this output to Pixhawk RC IN, how to do it is written in the rx manual (rx in mode 2).
First, sorry for my english, it's not my native language. Not sure if this is a bug but I have some problem with Pixhawk and software 3.2rc5. What's going on? I cannot arm in stabilize mode in home (didn't try yet outdoor).
1. Pixhawk connected to PC via USB
2. Transmitter ON
3. Power battery connected to power module
4. TX, ESC, compass, acc: callibrated
5. Safety switch ON
6. Now - trying to arm and I hear only two beeps, nothing happens
7. Now I change ARMING_CHECK to "Skip GPS"
8. Trying arm again - it works now
9. Now it's strange, because I change ARMING_CHECK to Enable and after that, I can arm motors.
10. When I disconnect power and trying do this again, the same scenario.
I see only "Bad/No Terrain Data" on Flight Data screen of Mission Planner after connecting to Pixhawk. What does this mean?
I guess you have not a 3DR Pixhawk. So your GPS takes a very long time until it has HDOP below 2.0 because the Battery in the Pixhawk is missing and/or you are not under the free sky view. Go outside or rise the Value for HDOP. It is not a issue of the Beta.
have a nice Day, André
Hi André,
What is the battery on the Pixhawk actually for?
