If you reported a CASA bug or requested a new feature through the helpdesk and were told the developers have been notified, you can check development team progress at http://casa.nrao.edu/hdtickets.
Search for your helpdesk ticket number in the top right of this webpage and you will find the corresponding development ticket. Alongside the NRAO helpdesk ticket number is a brief summary of the development ticket, including the ticket status, the version of CASA in which the change will be implemented, and the determined resolution. If you have questions about the status of the issue, please post a reply to your original helpdesk ticket or create a new ticket and NRAO staff will respond as soon as possible.
