  7. Refers to setting specified message types as low-priority-level messages (up to 20 message types). When the server load is high, if a low-level message is received, it is dropped first. For example, if an app has a customized message type to achieve “Like” function, they can set it as a low-level message type, and this type of messages are preferentially discarded when the volume of messages in the chatroom is large. ↩︎

  8. Refers to chatroom message/user whitelist function. The whitelist of chatroom users can be used to protect important users in specified chat rooms, and you can set whitelist users by chat room. For example, you can protect users with important roles such as administrators and anchors in chatrooms. The room message whitelist can be used to protect specified message types in all chatrooms under the app. For example, customized red packet messages. ↩︎
