NEW

  • New room flag: SuppressPlayerInfo (0x40): When it's set:
    • Events Join and Leave are not sent. (same as SuppressRoomEvents)
    • ActorList int[] is skipped from join/create operation response.
    • Actor properties are skipped from join/create operation response.
    • Actor properties changes are never broadcast. Room properties may still be broadcast and clients could request actor properties via OpGetProperties. Note that UserId is not broadcast which makes PublishUserId useless.
