I did a 400 mile drive on Sunday right after receiving 2019.32.11. Model 3, HW2.5, FSD, USA. While this is, of course, subjective, I can't say I noticed any improvement in how NoA handles lane changes - quite the opposite. As before, the car handled merges into traffic by drastically slowing down and often aborted the process after failing to find a safe opening because it was going significantly slower than other cars. I did notice that the blinker is now turned on at least a couple of seconds earlier than it used to be, well before the steering wheel vibration alert is triggered. This makes the entire merge take long enough to confuse other drivers into thinking you just left the blinker on, as illustrated by several drivers initially trying to leave me room and then speeding up after not seeing any action from my car. Also, "merging out of passing lane" behavior got broken for me on this release - while passing large trucks, the car repeatedly attempted to initiate lane changes long before actually clearing the vehicle it was passing, making me speed up to let it complete the merge safely. Despite some 15000 miles of NoA driving experience, this was a very uncomfortable. Finally, I also saw about a dozen of no-reason changes into the passing lane when there was no other traffic around me and the route did not call for it.
