When generating documentation, you have an option before creating a new deliverable.
A Major Version represents a significant change to the SSP. You can use this to represent new requirements being filled, new contacts being added or deleted, etc.
A Minor Version represents a marginally smaller change to the SSP. You can use this to represent grammar fixes, address changes, etc.
There is no set precedent on what defines a major vs a minor version of your deliverable. It’s simply a way for your organization to organize it’s deliverables as you work through an assessment.
