The Forum module is in the 'Testing' phase. In order to keep the Tracker module generic enough to be used to track any DNN module, the Testing phase has very generic work items. And while there are some specific tests, like Install, UnInstall, etc. most of the testing falls under a single work item, 'Additional Tests'.

Obviously testing a complex module like Forums will take a lot longer. So while it looks like there's been no activity in the past five days, what that really means is that of the work being done, none of it has been 'completed' in the past five days.  Trust us, no one wants the new version of the Forum released more than we do :)

Thanks for the detailed explanation.  That helps me understand the process better and hopefully others who are wondering too.
