It isn't direct answer for your question, here is a matrix Python,
Plone, Zope and ZODB's release.

       Plone	    Zope	   Python	ZODB
       2.0.5	2.7.0-2.7.9	2.3.4-2.3.5	3.2
       2.1.3	2.7.0-2.7.9	2.3.4-2.3.5	3.2
       2.1.3	2.8.0-2.8.8	2.3.4-2.3.5	3.4 (MVCC)
       2.5.0	2.8.7-		2.3.4-2.3.5	3.4 (MVCC)
       2.5.0	2.9.3-		2.4.2-2.4.3	3.6 (MVCC)

* Quoted from http://zope.jp/documents/faq/pythno-zope-plone-versions
  (written in Japanese).
* ZODB = Zope Object Database, component of Zope.
* MVCC = multi-version concurrency control

And there are more products which runs on Plone or Zope, and they
might depends on specific series of Plone or Zope.

(About relation between Zope 2.x and Zope 3.x, this figure might be

No concrete model at now, but I want to work on...
