Facebook just announced that end-to-end encryption is available for audio and video calls on Messenger.
The roll-out of the optional feature comes after the company saw a surge in the use of audio and video calls with more than 150 million video calls a day on Messenger in the past year.
The end-to-end encryption means that no one else, not even Facebook, can see or listen to what's sent or said. The feature was introduced for one-on-one text chats in 2016.
Disappearing messages has also been updated; users now have more options to choose the amount of time before all new messages disappear. For example, they can choose from as few as 5 seconds to as long as 24 hours for the messages to disappear. 
Over the next few weeks, Facebook will be rolling out test features such as end-to-end encrypted group chats and calls in Messenger and Instagram DMs.
