WhatsApp had already introduced Group Calling feature for iOS and Android users. But, earlier it was a bit cumbersome to do so. Earlier, to do a group video call you need to first call a single person and then click on add participant button to add more users into the group call. But, with the latest beta update, the process has been made much simpler. Now you can directly do video calls to selected people in a group in just one go without any hassle.
The update is only available for iOS users as of now. But it will be available soon to Android platform users as well. The user can select up to three members they want to do a group call with, and then press the audio or video call button to start the group audio or video call immediately.
The update brings in many other bug fixes as well. Such as automatically getting unintended haptic feedbacks and automatic dismissal of members as admins, fixed some localization issues when chatting with businesses, and it fixed some issues when searching for chats, contacts, and messages.
The update seems to be launched soon for stable users as well. And then in a week or so should be available for Android as well. WhatsApp had also recently introduced stickers feature in the app which also included many regional stickers.
