WhatsApp launches group calling over voice and video

WhatsApp has launched group calls for voice and video.
You can make a group call with up to four people total. Just start a one-on-one voice or video call and tap the new “add participant” button in the top right corner to add more contacts to the call.
Group calls are end-to-end encrypted, and are designed calling to work reliably around the world in different network conditions.
So go ahead and update the app.
