+Please note: depending on which version of Chef and which version of Supermarket you are running, you may support the new "extended" metadata fields. By default, Stove reads but does not write these new fields when uploading cookbooks because it is not backwards compatible.

+
+```bash
+$ stove --extended-metadata
