+gdebi (0.9.5.7+nmu1ubuntu2~ppa1) artful; urgency=medium
+
+  * Finish the policykit port:
+    - gdebi-gtk-pkexec isn't needed, root access is only needed for the
+      package installation and removal.
+    - Install the policykit file (create debian/gdebi-gtk.install).
+    - Modify the gksu commands in GDebi/GDebiGtk.py to call pksu instead.
+    - Drop the dependency on gksu and only depend on policykit-1.
+    - Thanks for the initial work, Julien!
