Latest Viber update brings pinned messages, replies in group, more
Pinned messages
These pinned messages are displayed on a purple banner to make them even more visible, and they should persist even when the conversation continues. Also, any message in a chat can be pinned by long-tapping on it and choosing the appropriate option (“Pin”).
Reply messages in group
Another new feature included in the update is the option to reply to specific messages in group chats. Now, whenever you long tap on a message, you can select “Reply” and the message sent will be given context when the conversation may have already moved to another topic.
Furthermore, broadcast lists allow Viber users to share the same message with multiple recipients privately. It functions like an alternative to creating groups of unrelated contacts in order to send a message that's important for all of them. Broadcast lists can be saved once they are created and the first message is sent.
The new Viber update is currently rolling out to all compatible Android and iOS devices. Since this is a staged release, it will become available globally to everyone in the coming days.
