This subsection is also defined in the DTR report. When the penetration test is performed, the report is not finalized in one go. A lot of changes need to be made by both sides so that a balanced report is created that is acceptable to the client and the tester. An initial draft of the report will be made and sent to the client. This subsection logs the number of changes that were made to the report from the time of its initial draft. Each change defines a new version. When the report is finalized, the version number is also mentioned in the report.
