+Change: Include full key ID in JSON output of `key list`
+
+We have changed the JSON output of the `key list` command to include the full
+key ID instead of just a shortened version, as the latter can be ambiguous
+in some rare cases. To derive the short ID, please truncate the full ID down to
+eight characters.
