WhatsApp has announced a handful of enhancements for group calling over the encrypted platform, including seamless call transfers across devices and a new web calling feature. It's now possible to make and receive audio and video calls, including both one-on-one and group calls, directly from WhatsApp Web. Then there's the new Waiting Room, which appears when creating a WhatsApp call link with "Require approval to join" enabled. Participants now enter the waiting room first until the host is ready to let them in. WhatsApp says the slate of new features are rolling out gradually and will be "available to everyone soon."
