Kanban view : Color change in the WIP Limit

One answer

The coloring of the plan header for the Kanban view is currently incorrect (and tracked in this defect). There are a collection of enhancements currently planned around the Kanban view.

Hi
Is there any change in the latest 4.0.5 release?

The coloring issue has not been addressed but there is an updated Kanban/Taskboard implementation in preview mode as part of 4.0.5. See https://jazz.net/wiki/bin/view/Main/PlanningKanbanTaskboard2 for details on how to enable it.
