python-zope.app.principalannotation 3.7.1-0ubuntu1 (i386 binary) in ubuntu trusty

 This package used to provide implementation of IAnnotations for zope.security
 principal objects, but it's now moved to the ``zope.principalannotation``
 package. This package only contains a bootstrap subscriber that sets up
 the principal annotation utility for the root site and the browser add
 menu item for adding the annotation utility through ZMI.
