 ### Added
 
+- A zone's page links to the same zone in the other views ("also in
+  external"), in each view's colour, keeping the tab you are on. It
+  works for zones that aren't linked too, and the zone API's new
+  `in_views` lists them.
 - `jarl.service` has the alias `jarld.service`, so `systemctl restart
   jarld` works too. The alias is linked when the unit is enabled; the
   package relinks a unit enabled by an older version on upgrade.
