[Zope-dev] catalog upgrade - what about products which subclass zcatalog

[Ross Lazarus]

I just upgraded my site explicit ZCatalog objects using Chris's very
helpful http://www.zope.org/Members/mcdonc/HowTos/UpgradeToNewCatalog
instructions - but I have a bunch of catalog aware zclasses and some
zclasses which (eg zdiscussions things, based on ZDBase) use
Products.ZCatalog - given that the base class has changed, do they need
any tweaking to take advantage of the new b+tree code?
