In addition to that the update also brings something else new, which is Redesigned In-App Notifications On iOS.

According to WABetaInfo: “The user can now expand the in-app notification in order to show the chat preview: the chat preview is not static like the one that appears when you peek on a chat cell, so the user can scroll up and down the view to see older and newer messages. When you read messages from the chat preview, read receipts aren’t updated: WhatsApp will notify the recipient that you have read their messages when you open the chat normally or when you reply from the chat preview.

The new version of in-app notifications is already available for all the iOS beta users.
