Just did some test work on 28.3-0 on a save game fresh started in ACEO 28.0, playing on a Mac. Things I found so far:
Cars and busses still pile up and causing massive traffic jams, resulting in PAX not being delivered to remote stands, overtaking also doesn’t kick in (ACEO-6677):
Massive delays, caused by busses not arriving at stands, but also because the ‘Always send away’ function doesn’t work (manually dismissing planes works) and because of the point below, where PAX arrive and leave again (ACEO-6678):
Another thing as already mentioned by @sirhc80, I see PAX arrive at busstops and they leave again on the next bus, approximately 50% of the PAX makes it to the terminal the rest never even bothers (ACEO-6679):
Don’t know if the path finding system is confused because of all the delays and planes not having arrived yet and therefore the path finding system is making a decision that the PAX will not make it and thus decides to leave…?
Edit: added the bug report numbers.
