In addition to the features given by others, I believe AirPlay 2 significantly re-worked the way timing and sync works.
Previously I believe AirPlay (1) had a fixed 2 second delay, which was not a great UX and also caused issues in syncing multi-room (or multi-output) audio.
AirPlay 2 does this in a much more dynamic way that reduces the latency (anecdotally, maybe 100-200ms is typical) and improves the sync. I have no idea how it achieves this though.
