WhatsApp announced updates to group chats featuring an @all mention function, three poll improvements, and streamlined group creation. The @all feature allows alerting all members simultaneously for urgent messages like closures or deadline changes. Groups over 32 members restrict @all usage to admins only, and the mention bypasses muted chat filters unless users opt out via notification settings.

Poll enhancements include setting automatic voting deadlines, concealing voter identities, and a 15-minute window to edit poll questions after posting. These upgrades aim to improve clarity and reduce pressure on participants.

A new "Create a similar group" option enables users to spawn new groups with existing members in one tap, ideal for side conversations such as surprise party planning or focused topic discussions without disrupting the main chat. This follows earlier 2026 updates introducing message history, member tags, and event reminders. WhatsApp serves over 100 million users in the U.S. and 3 billion globally.
