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. The mention will surface even in muted chats, though WhatsApp says users can mute @all specifically in their notification settings if they want to opt out. Today's changes come as a continuation of updates introduced earlier this year, when WhatsApp added group message history, member tags, and event reminders.
