Just downloaded 2.0.8 from the planner. The winds here in the UK are making a real nuisance of themselves at the moment but despite the weather I was able to do a brief test and it flew okay in Stable mode. However, I see that the yaw 'unwinding'* issue is still there. Several people have mentioned this and yet it has remained a small but noticeable problem for some time. Would it help if I made a short video of the problem so that the project team can see what is happening or is it a known and difficult issue to resolve?
* The yaw unwinding issue as far as I'm concerned is where you provide a yaw command, the copter then rotates but when you release the rudder stick the copter rotates back in the direction it had come from around 10 or 20 degrees.
Please update to 2.0.13 in the downloads section. Most of the Yaw problems are fixed.
