+##  Group Issue Board
+
+>Introduced in GitLab 10.6
+
+Group issue board is analogous to project-level issue board and it is accessible at the group
+navigation level. A group-level issue board allows you to view all issues from all projects in that group
+(currently, it does not see issues from projects in subgroups). Similarly, you can only filter by group labels for these
+boards. When updating milestones and labels for an issue through the sidebar update mechanism, again only
+group-level objects are available.

 ## Tips
