The QR code feature lets users add up new contacts easily. Here, all you need to do is scan the other device’s QR code and then they are added to your contact list automatically. For video calls, users will now be able to enlarge a participant’s video to fill the entire screen during a group video call.

A new video icon will also be made available in groups with up to 8 members. When you click on this icon, you will be able to start a video call directly with all the other participants rather than needing to add them individually. The WhatsApp dark mode which has been available for mobile devices since March is also expected to launch on WhatsApp Web. These new changes are expected gradually in the coming weeks, as we are not certain what regions will receive these updates first.   References
