Recommended Zope Version for Plone 2.5.3?

Hello. We are about to migrate to Plone 2.5.3. The release
notes say to use 2.9.7+.  Zope 
2.10.3 is the latest stable.  What version of Zope is
optimal in users experience? Are we safe 
to use 2.10.3?

A note for the developers -- my group finds this kind of
documentation vagueness 
problematic; we have spent too much time chasing down minor
or major problems because 
we chose the wrong subversion of Zope as a base. It seems
common to be told later by a 
core developer "in the know" that we chose the
wrong version of Zope (2.95 instead of 2.96 
for example) because "everybody' knows about this or
that particualar nasty bug.

A clear indiciation of the recommended Zope version in the
"Full release announcement" 
would be most helpful. 2.9.7+ is too vague. If I were a
niave user I would choose Zope 2.10.3 
and my intuition tells me that I would have problems because
of that choice.

In "2.9.7+" only the "7" is meant as a
minimum.  So: 2.9.8 etc would
be fine, when they come out.  Maybe this can be phrased
better yes.

2.10.something would not be good.  At least I assume that
Plone 2.5
will not work on Zope 2.10.  Also not on zope 3.*.

It *does* help to keep an eye on various mailing lists.  And
some
compatibility issues will only be found out after a Plone
tar file has
been made.

Maybe zope 2.10 or zope 3.* is mentioned in the plone
install docs as
not working.  At least it would improve clarity to add
this.

Can you open a bug report in the plone issue tracker?

I'd bet that in 90% of these cases, we have discovered the
problem after  
the release. The most recent example was the date/time
problems in Zope,  
which we didn't know about until after we had shipped that
release of  
Plone — and there was also no fixed release of Zope for a
while, so there  
wasn't much we could do about it until later.

The install text says that 2.10 will not work. Generally,
you can never  
use newer major versions of Zope than the one we state are
compatible.

The main download page says:

Current release: Plone 2.5.3
Released May 18, 2007 — tested with Zope 2.9, Zope 2.8

…which should clue you in to the fact that Zope 2.10.x is
not tested or  
supported.

(We do have a bit of a special case with this particular
release because  
of the security fixes in a dot release of Zope, so we
recommend the 2.9.7  
release to make sure you are protected)
