Don’t know who to tell, but there is a terrible problem in the Elm Guide.
on the JSON page, getting random cat pics is NO LONGER working!!!
The shape of the json has changed, so the decoder on lines 120-121 needs to change to
gifDecoder = field "data" (field "images" (field "original" (field "url" string)))
Please let whoever needs to know, as seeing random cat pics is IMPORTANT.
