Facilitates handling of draft revisions
API module for handling drafts of revisions. This module doesn't provide any workflow handling, but it should provide robust mechanisms for creating new revisions as drafts, publishing revisions, and deletion of old drafts. The goal of drafty is to be a dependency for workflow modules such as Workbench Moderation , CPS  (and others). Currently, each of the workflow modules has their own implementation for saving draft revisions.  https://www.drupal.org/project/workbench_moderation  https://www.drupal.org/project/cps
