Hi!

I just pushed -03 with these changes

   o  Changed v5 key fingerprint format to full 32 octets.

   o  Added Literal Data Packet format octet 'm'.

   o  Added Feature Flag for v5 key support.
      [Not yet discussed in the WG]

   o  Added AEAD Encrypted Data Packet.
      [I also added a feature flag and a Preferred AEAD Algorithms
      signature subpacket]

   o  Removed notes on extending the MDC packet.
      [Not yet discussed in the WG]
   

I also noted

   o  The OCB mode is patented and a debate is still underway on whether
      it can be included in RFC4880bis or needs to be moved to a
      separate document.  For the sole purpose of experimenting with the
      Preferred AEAD Algorithms signature subpacket it is has been
      included in this I-D.



Shalom-Salam,

   Werner
