[Zope] Guestbook Product

Has anyone else noticed that the GuestBook Product no longer works in 1.10? Is it just me or what? I get a traceback of Traceback (innermost last): File "/usr/local/Zope-1.10.0pr1-src/lib/python/OFS/Application.py", line 393, in import_products product=__import__(pname, global_dict, global_dict, silly) File "/usr/local/Zope-1.10.0pr1-src/lib/python/Products/GuestBook/__init__.py", line 7, in ? import GuestBook File "/usr/local/Zope-1.10.0pr1-src/lib/python/Products/GuestBook/GuestBook.py", line 7, in ? from OFS.Document import DocumentHandler, Document ImportError: cannot import name DocumentHandler Any Ideas?
