I'm using 2.9.4 with Five 1.4 and formlib.
Having Zope 2.9.5 required for next Five 1.4 release seems to be
acceptable for me.

Maybe it is good moment to do something with DateDisplayWidget?
I mean - remove reference to 'request.locale' from it's code.
There was a long thread about this on Zope list and I've even send
proposal of modified code there.
