+      hash: f1bd4b8d9bcef29e326cbf97eaddd837c2704d19
+      body: >
+        The image manager module now uses tags instead of docker IDs as the main
+
+        way to identify docker images on the engine. That is, if the target
+
+        state image has a name `imageName:tag@digest`, the supervisor will
+        always use
+
+        the given `imageName` and `tag` (which may be empty) to tag the image on
+
+        the engine after fetching. This PR also adds checkups to ensure
+
+        consistency is maintained between the database and the engine.
+
+
+        Using tags allows to simplify query and removal operations, since now
+
+        removing the image now means removing tags matching the image name.
+
+
+        Before this change the supervisor relied only on information in the
+
+        supervisor database, and used that to remove images by docker ID.
+        However, the docker
+
+        id is not a reliable identifier, since images retain the same id between
+
+        releases or between services in the same release.
