WhatsApp confirms 3 new features including 'view once' feature

Facebook CEO Mark Zuckerberg and Head of WhatsApp Will Cathcart confirmed to WABetaInfo that three new features are coming to WhatsApp. The "view once" feature will let users send content and have it disappear after the recipient sees it. Users will be able to connect up to four devices to one account and enable 'disappearing messages' for all new chats.
