[Zope] Update from Beehive ZClass manual ?

Hi Mark, In your last message about ZClass ( http://lists.zope.org/pipermail/zope/2000-June/026685.html ) your wrote :

thanks! the cool thing about our tutorials is that all our customers get free updates for one year --- giving us bees a chance to correct any errors as well as document any (in this case ZClass) new features/changes.

So, when will come the next update of ZClass manual ? Will you add a part for non beginner, and if yes what one could expect ? FR
