Here is a short summary of the changes in the document:

* Added section to describe how phase 2 authentication hashes should
  be changed to fix the unauthenticated isakmp header problem in the
  phase 2 exchnages. 

* Changed the authentication hash to be hash of hashes instead of hash
  of the full packets. This way the memory consumption used to before
  calculating the hash is smaller, and the same per packet hash can
  also used to detect retransmission packets.

* Added more text saying that the template hash/sig payload must
  contain generic payload header, but only the contents of the hash/sig
  field itself is all zeros.
