[Zope] Zope 2.6.2 Beta 4 Released

[Dennis Allison]

Hi Matt --

I encountered a problem with ZDiscussions due to a Lasy Map Instance not
getting properly unwrapped.   This in an unmodified portion of a long
runnning hybrid ZClass/Python Product system.  We have a workaround--
using the ZUBB follow-on product that seems cleaner and more stable--
but I continue to wonder about that ZDiscussion worked at all on 2.51 
and earlier systems, but died on 2.6.2b3.  Is this (was this) a bug
that got fixed or what?  Any comments helpful.

I'll upgrade to 2.6.2b4 immediately.
