This was an oversight; we have a two release deprecation policy (with
inline warnings + mentions in the docs) which was not followed in this
case.  The internal API change was documented in the v0.9 api_changes
document, but unfortunately not the rest.

I spoke to Brian several months ago to fix the issue after this came
to our attention, but I guess the changes have not made their way
through to ipywidgets.

Of course, you are right, this type of thing should never, ever
happen--I apologize for the confusion and wasted time.

The Image class, just like most other numpy subclasses, turned out to
be a mistake.  It wouldn't carry through the whole pipeline, and ended
up causing more confusion than what it helped.

I've factored out the source and attached it here, in case that is of some help:

from image import Image
from skimage import data
cat = data.chelsea()
Image(cat)
