Some types of content, such as feeds, typically won't require revision control. By default, content that is deeper and more complex, such as book and feature story content, is configured to automatically use revision tracking in OSU Drupal.

If you create a new custom node type, and wish to automate your revision tracking, you'll need to configure it to do so.

The architect of an OSU Drupal 7 site can do this by adjusting the Publishing Options of a node type.
