Dashboard filters affect the data displayed on the dashboard. You can now easily share your filter, as well as the entire dashboard on which this filter is added, with other project members.
However, these users will need the same rights as yours, otherwise they may see different content or no content at all.
To share the filter and the respective dashboard, click the 
Share filter url icon in the widget’s header bar.
Details about this functionality are described in General widgets > Additional functions of filter widgets.
