From: andi@zend.com (Andi Gutmans)

Yes it does require changes in the extensions. I must say we=92ve been =
able to hammer through them pretty quickly but it does require change =
due to the refactoring of the data types. It=92s a refactoring exercise =
though not a rewrite. So relatively speaking not too painful and I think =
we=92ve already worked through many of them so there are a lot of =
examples.
