Things Changed or Removed in Content Controller v4.1
Reporting Changes
The Content Usage Overview report page is now two separate pages. These pages cover course and equivalent usage. This change will help you report on usage for large numbers of content or equivalents.
Breaking Changes
Due to the addition of Custom IDs any account, content, bundle or equivalent ID that is returned as part of a Public API call will now be a STRING. Previously each ID was returned as an INTEGER.
To match the naming convention of the rest of the data returned, course_version has been renamed to CourseVersion in the usage report endpoints. These endpoints are usage/InteractionHistory, usage/LearnerHistory and usage/RegistrationHistory.
