- issue2550796: Calendar and Classhelp selection tools don't cause onchange event to be triggered. Using the helper popups for modifying lists of users, lists of issues, dates etc.. now trigger the change event on the form's field. This allows onchange javascript to trigger to highlight changes, recalculate other form values etc. See ``upgrading.txt`` for details on applying these changes to your tracker.
