+* RBD: `rbd device unmap` command gained `--namespace` option.  Support for
+  namespaces was added to RBD in Nautilus 14.2.0 and it has been possible to
+  map and unmap images in namespaces using the `image-spec` syntax since then
+  but the corresponding option available in most other commands was missing.
