Not so many bug reports this time! - i'm running 8.4 on the main site and all is looking great!!
I have a minor helpdesk bug though.
When creating a new ticket, you are allowed to use quote marks i.e. " in the ticket title. However, when "updating" a ticket with said " marks, you get a horrible error message :)
Easily gotten around, but a bug for the reporting non-the-less!
Thanks again for 8.4!
