+xfce4-utils (4.8.3-1ubuntu2) precise; urgency=low
+
+  * Use maintscript support in dh_installdeb rather than writing out
+    dpkg-maintscript-helper commands by hand.  We now simply Pre-Depend on a
+    new enough version of dpkg rather than using 'dpkg-maintscript-helper
+    supports' guards, leading to more predictable behaviour on upgrades.
