WhatsApp Adds @all Mentions, Side Chats, and Poll Upgrades to Group Chats

Meta is introducing @all mentions, one-tap side chats, and enhanced poll features to WhatsApp group chats. The @all feature notifies all group members simultaneously, but in groups with more than 32 members, only admins can use it. Additional updates include creating new groups from existing ones without manually adding members, as well as poll end times, hidden voter names, and a brief editing window.
