osTicket v1.10 (stable) and Maintenance Release v1.9.15 are now available! Go get it now
I made a upgrade test in my OSticket 1.6 instalation to 1.8 version.
After upgrade, all the old attachments of my tickets couldn't be acessed in ticket edition. Despite, they are all in the subfolders from folder "uploads".
New attachments appear normally in the ticket edition.
