Two new features coming soon.
Real-Time Location Tracking
This feature tracks your movements and will allow your contacts see your current location. Of course, that also means WhatsApp knows where you are at any given moment!
The advantage of this feature is it will make it easier to for members of a chat group to find one another during meet-ups.
Revoke, Recall, Edit Messages
With this feature, you would be able to edit or even completely revoke messages that have already been delivered to contacts. This would save WhatsApps users embarrassment in instances where messages were sent by accident or which later were discovered to contain errors or information not to be disclosed in the content.
