I was exploring one of the new caves and marked my way with torches. When I came back all of the area was dark. Placing or breaking blocks didn't update the light for me. You have to either break a torch or place a new one to normalize it.
Still an issue as of 1.17.30 and the latest beta 1.17.40.20. It's probably better, but projectiles are still very choppy the further away they are from the player.
