In short, you asked you got it.

1. Canned messages by department
2. Personal canned messages. To operators role have to be assigned "Users" => "Allow user to have personal canned messages"
3. Now then user closes a chat and operator sends a message to user, chat widget will reopen at site.
4. Option to hide default form fields. These fields can be prefilled but they won't be visible by user.
5. Option to specify max mind city database file.

execute doc/update_db/update_65.sql for update and follow standard upgrade tutorial.

At this release I would like all users to pay attention at 3 item. Previously then user closed a chat without operator reply the only way to contact to user was send him an e-mail or just home that user will resume a chat. Now if you just write a message back to chat. To user will be shown chat widget again. If you are using pro active invitations checks, user even won't have to make a page refresh.

P.s don't forget to danate :)
