How should I modify the custom widget in the recipe examples to make it work 
with 3.2.0 ?
As it is, the program does not work from chapter 7 onward

I get this on at every attempt to 
display the widget:

    instance = self._widget_factory(*args)
TypeError: __init__() takes exactly 4 arguments (3 given)

If I take out the <widget> tags from browser/configure.zcml, the default widget 
works ok (but has a bug when I add two empty rows).

Other things I've already fixed with info from this list are the BrowserMenu 
and response.write
I guess for newcomers a page describing the few changes would be really useful.
