What's new in this version:
Your messages, photos, videos, voice messages, documents, and calls are now secured with end-to-end encryption, which means WhatsApp and third parties can't read or listen to them. Messages are automatically end-to-end encrypted: no turning on settings or setting up special secret chats to secure your messages. End-to-end encryption is available when you and the people you message are on the latest versions of WhatsApp.
