How these changes are found

Checks are matched across the two releases by V-number. A check counts as updated when DISA gave it a new rule revision (the r number in its SV-…_rule id) and its title, severity, check text, fix text, discussion, CCIs or other fields changed — the same comparison STIG Compare makes. Added checks are new V-numbers; removed checks are V-numbers V6R7 no longer has.
