Meta (formerly Facebook) has released a major update to Messenger to provide end-to-end (E2E) encryption support for group chats and calls. The feature extends Messenger's existing E2E encrypted messaging feature as it now allows you to encrypt group chats and calls. 
Along with encrypted E2E group chats and calls, the latest Messenger update brings notifications in case anyone tries to take a screenshot of messages (before the same feature was only available on Vanish function, which deletes messages when read).
For those who do not know, Messenger has been offering support for end-to-end encrypted chats for some time. The feature was first released in 2016 and as of today it finally supports group chats and calls. E2E encryption in Messenger is currently a feature that you can select by tapping the lock icon when starting a new conversation.
E2E encrypted messages are not the same as the secure Vanish feature available in Messenger and Instagram, as messages will not be deleted by default. However, it will notify you if someone takes a screenshot of a message. Surprisingly, Meta's WhatsApp messaging service still does not notify users if someone takes a screenshot of a message.
George is still wondering what he is doing here….
