(Needs to be backported, I think)

  Restores the old node API.

- Patch #76444 by chx, moshe, eaton, angie et al: make it possible to control access to form elements.

- Patch #77919 by chx, eaton, moshe, et al: enable programmaticaly submitted forms via the pull model.

See: http://drupal.org/node/64279#t-placeholders

- Patch #74326 by Eaton, Royboy, chx, et al: building $node->body with arrays like FAPI for viewing.

  Once again, we're paving the path for CCK in core ... :)

   + reorganized ?q=admin/settings
   + deprecated the _settings hook
