cck 6.x-2.0

IMPORTANT NOTES:
-------------------

- VIEWS INTEGRATION - Filters available for CCK fields in Views have changed slightly since the RC releases.
If upgrading from a previous CCK RC release, you might get errors or warnings when displaying some views,
or find they don't display the expected results. You'll need to edit those views and redefine their filters.
This only applies to filters defined on Text or Number fields that specify a list of 'Allowed values'.
Filters on other CCK fields are not affected.

- SECURITY FIX - This release fixes (minor) cross-site scripting (XSS) vulnerabilities
in nodereference.module, userreference.module, content_copy.module, and CCK's Views integration
See the Security Annoucement on http://drupal.org/node/330546 for more information.
