Portlets have a new infrastructure
Up one level
Portlets have been re-implemented using the Zope 3 component architecture. Change custom portlets to use plone.app.portlets if possible.
Old portlets are supported via a fallback mechanism called Classic Portlet; the portlet management screen has functionality for doing inline migration for old portlets. Note that using the old portlets mechanism will affect your site performance negatively.
XXX needs examples. (Martin?)
portlet_recent in plone3 ?
