[Zope] Question about Upgrading Zope and OS X Server

[Dan Gaibel]

So OS X Server Snow Leopard comes with Python 2.6.1. Is there any  
reason to think that this Python version would cause problems with  
Zope 2.8.6? We have had nice stability with Python 2.3.5. Either way,  
is Zope 2.8.7 a significantly better choice than 2.8.6?
