 As this is young module, new features are added in subsequent version. It's
 a good idea to specify version when using this module like this:
 
-  use Biblio::Isis 0.21
+  use Biblio::Isis 0.23
 
 Below is list of changes in specific version of module (so you can target
 older versions if you really have to):
