When preparing for a new session, a new version of each product needs to be created. This ensures that ongoing changes to the main (or base) version do not affect the courses that are in progress. For reporting, analytics and regulatory purposes, it means that a snapshot of the course, as it was when delivered during a particular session, is always available.
When a product is versioned the system creates a copy of the product, the content title(s) used (along with all packages, files, resources etc.), the objective(s) used and it creates a version of the curriculum.
