[silva-dev] trunk now needs Zope 2.8.4

[Martijn Faassen]

Hi there,

We're doing work to change the platform of Silva from Zope 2.7 to Zope 
2.8.4 + Five. The new requirement for the Silva CVS trunk is now 
therefore Zope 2.8.4 (and Five will soon be added as a requirement). 
We've already modified Silva and SilvaDocument -- SilvaExternalSources 
is next.

This also means that the trunk does not need to be compatible with Zope 
2.7 anymore.

Regards,

Martijn
