The Revised Final Report is the result of changes suggested by the Security and Stability Advisory Committee (SSAC).  The IRD-WG approved the changes with some additional minor edits.  You may be interested in the rationale for the SSAC's changes.  Most of the changes correct technical and other errors in the document.  The only substantive change is that the SSAC proposed an additional recommendation (recommendation 4). The rationale for this recommendation is that SSAC members asked why standards agreed to in Section 4.2 of the report were not part of the final recommendations for action.  For example, Nameserver, Phone/fax, Dates, Registration Status are fields where the IRD-WG had rough consensus on the standards, but in the original report there was no recommendation relating to these standards. Recommendation 4 suggestions actions that could be taken on those standards.
