+  * `XMonad.Actions.CycleRecentWS`
+
+    - Changed the signature of `recentWS` to return a `[WorkspaceId]`
+      instead of a `[WindowSet]`, while `cycleWindowSets` and
+      `toggleWindowSets` now take a function `WindowSet ->
+      [WorkspaceId]` instead of one to `[WindowSet]` as their first
+      argument.  This fixes the interplay between this module and any
+      layout that stores state.
