Shoppers and admins can now delete a conversation

Conversations used to be permanent once started. Two new controls change that:

• In the chat panel's header menu, next to "New conversation," shoppers now have a Delete this conversation option. Confirming it permanently removes that conversation and all its messages, then starts them fresh on a new one. It only works while their browser still holds the cookie tying them to that conversation. Once that's gone, a past conversation can no longer be singled out for deletion.
• In the dashboard, opening a conversation now shows a Delete button if your role allows it (Admin, today). It asks for confirmation, then permanently deletes the conversation and its messages and returns you to the conversations list.

Either way, deletion is permanent and immediate: there's no way to recover a deleted conversation.
