+### Upcoming date filter change
+
+In the [epics](https://gitlab.com/groups/gitlab-org/-/epics/6046), we plan to alter
+the date filter behavior to filter the end event time of the currently selected stage.
+
+The change makes it possible to get a much better picture about the completed items within the
+stage and helps uncover long-running items.
+
+For example, an issue was created a year ago and the current stage was finished in the current month. 
+If you were to look at the metrics for the last three months, this issue would not be included in the calculation of 
+the stage metrics. With the new date filter, this item would be included.
