Yeah. Docs.ckan.org always shows the latest docs (from master) now. New 
features are supposed to be marked with .. versionadded: 2.2 etc, so 
that people can see when a feature doesn't exist in their version of 
CKAN (it's in the documentation guidelines!). I'll have to remember to 
add one for this feature
