Drupal 6 is the latest version of the Drupal CMS that introduces many new features and improvements. Drupal 5 is a tested, stable architecture, but many new sites will want the features of Drupal 6. While ISUS has a long operating history with Drupal 5, we have had less time to test Drupal 6 for security and stability. As of this writing Drupal 6 sites are approved for development and deployment in the same manner as Drupal 5 sites. Please refer to the list of Drupal approved modules for details on modules that are currently available for Drupal 6. Bear in mind that this list is growing. There is currently a backlog of modules to be reviewed for Drupal 6 but please submit modules that are not listed and they will be added to the review queue.
