Thanks for the reference. The Roundup Issue Tracker uses CGI and FieldStorage/MiniFieldStorage extensively as well as cgitb.
Sadly it does mean that Roundup will no longer work with only the standard Python library which has always been a goal.
Even though CGI is inefficient, the CGI deployment mode works fine for low volume trackers on cheap hosting environments.
Hopefully we can work around the depreciation and keep Roundup alive.
