+  * Team upload
+
+  [ Ondřej Nový ]
+  * d/copyright: Use https protocol in Format field
+
+  [ Simon McVittie ]
+  * Change Maintainer to GNOME team at maintainer's request
+  * Preferentially build-depend on libgdk-pixbuf-2.0-dev.
+    We don't need the deprecated Xlib integration that is also pulled in
+    by the older libgdk-pixbuf2.0-dev package (see #974870).
+    (Closes: #976032)
+  * d/control: Trim trailing whitespace
+  * Set debhelper-compat version in Build-Depends
+  * Remove Section on libmediaart-2.0-0 that duplicates source
+  * d/upstream/metadata: Add
+  * d/tests: Add a superficial autopkgtest
