WhatsApp introduces opt-in group message history sharing, securely sending 25–100 recent messages to new members.

WhatsApp has launched Group Message History, letting admins and members manually share 25 to 100 recent messages when adding new group members, helping them catch up without sifting through old chats. The feature is opt-in, end-to-end encrypted, and clearly marks shared messages with timestamps and sender info. All members are notified when history is shared. Admins can disable the function entirely. Rollout is gradual, with availability varying by region and device. The update aims to improve onboarding in active groups while preserving privacy and user control.
