osTicket v1.10 (stable) and Maintenance Release v1.9.15 are now available! Go get it now
Exporting Data appears to only export 'open' tickets (v1.10)
Just upgraded to v1.10, noticed 1 potential flaw (or operator error).
When performing an 'advanced search' to show tickets within a time period (both open and closed) the list shows correctly on screen. Clicking Export at the bottom creates a CSV file containing only OPEN tickets.
It appears that any choices made for the screen view work correctly, but all roads lead to the same 'open' tickets only exported CSV file.
