ZPatterns "0.4.3final" contains a serious bug which deletes all ZODB-stored
contents of a Rack when you use the manage_pack method.  This bug only
affects you if you store Rack-mounted objects or attributes in the ZODB,
and does not affect you if your objects are entirely contained in an RDBMS
or other mechanism external to the rack.  If you've upgraded to 0.4.3,
please do not use manage_pack!

I have uploaded new versions of ZPatterns and PlugIns to fix the problem
with packing racks, and to provide "experimental" support for Zope 2.4b1.
(Specifically the problems reported below with expr_globals and ts_regex
have been fixed.)  Please upgrade to 0.4.3p1 before using manage_pack, or
if you wish to experiment with ZPatterns on Zope 2.4b1.  Thanks.

Thanks too, to Juan Palomar and Itai Tavor for providing information and
