How to create node reference fields in Drupal 7? I am puzzled. This was a very valuable option in D6 CCK, but since it moved into core, I can't find the option to create a noderef field (found a term reference field, though). I know it must be out there, where is it?
The project that maintains the Drupal 7 versions of the "node reference" and "user reference" field types is References.

Part of the code of CCK has been ported in core code, but some code is still living in third-party modules. CCK itself has a version for Drupal 7, which contains the code to update from Drupal 6 to Drupal 7 (among other things).
