WhatsApp has officially announced that it will be introducing a new 'Disappearing Messages' feature through an update that rolls out globally this month. The details of the new feature, however, have been out since earlier this week after an FAQ page created by WhatsApp was noticed. The long-anticipated ephemeral messaging feature pioneered by Snapchat was first spotted last month through a WhatsApp beta version. It will allow users to enable an option on individual and group chats that deletes new messages after seven days.
