WhatsApp has been hard at work as far as adding new features to the app is concerned, and continuing this trend of new features, the company has decided to now rollout a bunch of new changes for the beta users. You are now getting a brand new UI for contact info, new options for disappearing messages, improvement for multi-device support, and a few more changes.

Many of these features were already discovered through the APK teardown that takes place, but it is only now that WhatsApp has started rolling these features out. The new changes were spotted by WABetaInfo, and the first thing that the new beta update brings is the new UI for the contact info screen.
