         * "systemctl edit" has been updated to show the original effective unit
           contents in commented form in the text editor.
 
+        * Units in user mode are now segregated into three new slices:
+          session.slice (units that form the core of graphical session),
+          app.slice ("normal" user applications), and background.slice
+          (low-priority tasks). Unless otherwise configured, user units are
+          placed in app.slice. The plan is to add resource limits and
+          protections for the different slices in the future.
