WhatsApp Adds '@ all' Mentions and Poll Upgrades to Group Chats

WhatsApp today announced a series of updates to group chats, including an "@all" mention feature, three new poll upgrades, and a faster way to spin off new groups from existing ones. The most notable addition is @all, which lets a group member alert everyone in a chat at once instead of tagging people individually. WhatsApp says the feature is meant for important, time-sensitive messages, such as school or office closures, event deadlines, or last-minute changes to plans.
