+Change: remove the ownCloud storage driver
+
+We've removed the ownCloud storage driver because it was no longer
+maintained after the ownCloud SQL storage driver was added.
+
+If you have been using the ownCloud storage driver, please switch
+to the ownCloud SQL storage driver which brings you more features and
+is under active maintenance.
