+  * debian/control
+    - Provide transitional package for ubuntu-wallpapers-extra, an old package
+      which was providing the Karmic wallpapers and thus shared files with
+      ubuntu-wallpapers-karmic. (LP: #975778)
+     - Put ubuntu-wallpapers (the package) in Section: metapackages as
+       dependencies of packages in this section are considered "manual" by apt
+       and therefore will not be removed on upgrades. This means that users
+       will keep wallpapers from old releases when upgrading. Thanks to James
+       Westby for pointing this out to me. (LP: #863509)
