New in v6.4: - Connect faster: message instantly once you tap Connect. - Review group members: chat with new members before they join. - Chat with admins: send your private feedback to group owners. - New group role: Moderator - can remove messages and block members. - Improved message delivery - less traffic on mobile networks.
