[Zope] Zope 2.0.1 tree-tag problems

[katrin]

Hi,

Can anyone tell me how the tree-tag bug concerning expand_all was fixed in
Zope 2.1.0? 

I can't install Zope 2.1.0 because then the patched version of
the Confera Topic won't work anymore (don't know why).

Please, I really need your help with this.

Thanks,
Katrin
