I hope you don't mind me using your list as a comparison, I've added my comments base on my experiences of my first flights yesterday. After I had done the updates I calibrated everything (My logic being that any pre-stored bias, trim, offset values whatever they might be labelled would have been deleted).
1 Instability in manual flight (When I flew yesterday I was already aware that some were reporting instability in flight. During my flights I was surprised at how stable all appeared to be)
2 Terrain following, doesn't (This was my first ever use of 'Terrain Follow'. I found this to work well with me walking up a steady incline of about 10 degrees over a distance of about 200 yards. on the return part of the journey the aircraft did not descend to follow path downhill (what I expected). (according to the spec' 'Terrain Follow' only operates on slopes up to 20 degrees)
3 A lot of wobble when using the new 'draw path' mode (whatever it's called) (I did not test the draw function)
4 A number of high wind warnings on a calm(ish) day (I had several of these warnings during my flights at three different locations, there was a moderate wind varying 6-12 mph.)
5 Video transmission dropout between drone and controller, even at short range (I witnessed this on one occasion during my one hour of testing, under the strongest wind during my testing (very hard to judge but possibly 20 mph) I had the Gimbal flip right and video loss for 2-3 seconds. This was open area, direct line of sight at about 841 feet from home. It may have been interference from my device wifi, or my cell phone, or perhaps a bug in software/firmware).
6 The drone 'feels' more sensitive to the controls (a bit skittish) (I would agree more sensitive to controls, but that's probably down to 'Expo' settings etc)
My first impressions of using the updates on my P4 were good, I was surprised at how steady the hover was. I tested hover out from a few inches off ground up to head height and saw no problems.
(And I'm keeping an open mind on, and will continue to watch for instability)
EDIT:- I'd forgotten to mention the one thing that I was focussed on was horizon level on the P4 with updates. Where I fly there usually is never a flat horizon, so if it were slightly off it would hardly be noticeable. After the update I flew in areas where I could test this, and was happy that the horizon was level, stable, and could survive several 360 degree full speed yaws without any apparent problems.
