Two new features for group chats and communities have been revealed by WhatsApp. The first one is a privacy enhancement that gives admins the power to control who has access to a group or not. Previously, anyone could sign up via a link that any member provided as an invitation. Usually, little flags in the chat that show a new member has joined the group might easily vanish from view after a few messages. This change can guarantee that conversations and information are shared with the right people.
