Change all references to "portal_metadirectories" to
"portal_directories".
Replace "display_prop" (property of a directory) with
"title_field".
Replace references to directory_* skins by cpsdirectory_*.
Beware that some skin names have changed, and that the
parameters to cpsdirectory_entry_view are now "dirname" and
"id" (not "entry_id").
Calls to getEntry('foo') will not return None anymore if the
entry does not exist but raise KeyError. If you want None
returned, use getEntry('foo',default=None).
Replace "getSearchableSchemaKeys" by querying the schema
directly for the fields that you want.
Be aware that results from a searchEntry is different than
before.
