WhatsApp has released a new app update which raises its group audio and video call participants limit to 8 users at a time. The update also includes a few design tweaks, including support for iOS 13's new action menus.

It was speculated for some time that Facebook is working on upgrading WhatsApp's group call limit from 4 participants to 8 participants. The company officially announced the change a couple of days ago, while confirming that the calls would still be end-to-end encrypted. This announcement was accompanied with the launch of Messenger Rooms, Facebook's new video conferencing product which allows users to talk to 50 people at a time via video or audio, but without end-to-end encryption.
