 ### New features
 
+* `jj bookmark tug` finds the closest bookmark on a revision or its ancestors
+  and moves it forward to the latest non-empty descendant. This is useful for
+  advancing a bookmark after making several commits without having to manually
+  specify the bookmark name or target revision.
