I know most of the time the "changes" reported after a software update are perception between slightly different drives, but I'm quite certain there have been some changes to AP behaviour with this version. My car is now very skittish at passing cars on the motorway. If a car in the lane to the left moves even slightly closer it will lift off and not pass them until I intervene.
It got so irritating this past weekend on the M25, that I had to ride the accelerator when passing most cars to keep it going. Yes, I could have turned AP off, but I prefer to have the autosteer than nothing at all... Before updating to 2023.32.4, if anything I would have said AP was too confident with minimal space when passing cars, but now it's very very different and over-cautious.
I can't speak to stop-start traffic, I haven't had the pleasure of needing to do that since the update. Though I am commuting into London on the A40 tomorrow, so I'll try it out then.
