WhatsApp is working on a feature called 'Past Participants' that will allow members of a group to check who left the chat in the past 60 days. It is currently available on iOS beta.
View expired disappearing texts
Users will soon be able to keep disappearing messages even after their expiration.These messages will be stored in a new section of the chat info called 'Kept messages.'
Filter for unread chats
WhatsApp will soon allow users to filter their chats by displaying new messages. The unread chat filter will permit people to view the list of all their unread chats.
React to status updates
WhatsApp will soon permit users to react to status updates with eight emojis. Once the reaction is sent, the emoji will be seen as a status reply within the chat.
