WhatsApp coming with new feature which will allow users to create a link to join a group and then can share it via other apps, or also can print it as a QR code. So you will won’t need a phone number to add anyone in the group.
They are also working on a new video calling feature. That will let you call to your contact over mobile data and WiFi connection through whatsapp.
A third new feature is the Zip File Sharing option: WhatsApp already added doc sharing feature in their app, which allow users to share .pdf files to share. They are expanding that feature to support ZIP file.
Whatsapp groups invites will look like this: i.e: (https://chat.whatsapp.com/ghhggjbdgm.)
