Multiplayer: Multiplayer games are now ended if a player disconnects, times out, gets kicked etc. Previously it would not register correctly if the player didn't manually close the inventory which would simply leave the game open with the remaining player waiting.
Particles: If a player timed out or lost connection to the server and the invulnerability particle sphere was active it could get left behind for a few minutes. The player's connection is now checked when the sphere updates which will make it disappear immediately if the player is no longer online.
