[Zope] Overview of changes in 2.7.0 ??

I am running 2.6.* and is trying out this newfangled Zope 2.7.0 thing. I have no problem setting it up, getting it running etc. But is there any good documentation on what the changes are, and what they mean. The closest I could come to something readable was: http://www.mechanicalcat.net/richard/log/Python/What_s_new_in_Zope_2_7_0 But that is a bit short on information. regards Max M
