Topic on Extension talk:GoogleDocs4MW

I noticed that GoogleDocs4MW creates an iframe with an URL like this:

http://spreadsheets.google.com/pub?key=XXX&output=html&widget=true

Is this kind of URL still valid in Google world? I can't make it working. The correct URL form for public Google spreadsheet seems to be this:

https://docs.google.com/spreadsheets/d/XXX

Also this form seems to be correct:

http://spreadsheets.google.com/ccc?key=XXX&output=html&widget=true

I modified the GoogleDocs4MW.class.php source code and it works now.
