[Zope] Overview of changes in 2.7.0 ??

[Max M]

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:

But that is a bit short on information.
