I don't see how UpdateSupport applies to updating existing class instances...it seems to be for some 2.3.x catalog upgrades and Core Session Tracking?

Nope, those are example updaters, the idea is that you write one that does what you need, you can look at them for clues though...

Also, you could just add class variables to your object's class which have sensible default.

I don't understand - previous instances will not have the properties unless they are updated, correct?

Aha, you're talking about properties... yeah, you'll want an updater for this :-/ cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
