I just finished working on zope's intid and keyreference packages. The whole key-reference stuff is now moved in zope.keyreference package and the new version of zope.app.keyreference is released that only contains compatibility imports, so it makes no sense to depend on zope.app.keyreference anymore - use zope.keyreference. All functionality of zope.app.intid, except ZMI stuff is moved to the zope.intid package. Old zope.app.intid package now only contains browser pages and add menu item as well as backward-compatiblity imports. So if you are not using ZMI - zope.intid is for you. Next, I'm going to split zope.app.catalog and check other packages for uses of zope.app.intid/zope.app.keyreference (I guess some sqlalchemy-related packages can depend on keyreference stuff). -- WBR, Dan Korostelev
