Pavel Zaichenko has discovered a bug in PatchKit (And fixed it for me - Thanks Pavel) which prevents Packaging a product using PatchKit if you use INSTANCE_HOME (As far as I can tell, this is the only situation where it would fail). Version 4.1.4 fixes this, and has a couple of other very small tweaks. The updated product is available from http://www.zope.org/Members/haqa/PatchKit Adrian... -- Adrian Hungate Try Zope - http://www.zope.org - You might like it.
