Messaging service WhatsApp rolled out new group-chat features on Tuesday, including more controls for administrators as well as regular group members.

Users can now leave a group permanently to avoid being repeatedly added back after they have left, Facebook Inc-owned WhatsApp said in a blog post.

Administrators can no longer be removed from a group they created and users can now quickly locate messages that mention them in a group conversation.

Groups on WhatsApp have taken a central role in the messaging service that has more than 1 billion users, helping connect people with similar interests across the globe.
