FYI,
the major changes in this version are:
4.12.3. Handling Conflicting SPI Values
* a new way to handle conflicting SPIs by utilizing multiple relayed
candidates
* this changed affected also sections 4.1, 4.2, 4.12.1, 5.13.
4.9. Mobility Handover Procedure:
* the exchange of locators must be three way in order to avoid replay
attacks
* clarified double jump
Minor changes:
4.7.1. Minimal NAT Traversal Support:
* clarified how mobility is supposed to work in this case
4.10. NAT Keepalives:
* the Data Relay Client and Data Relay Server MUST employ only HIP
NOTIFY packets in order to keep the server reflexive candidates alive
5.10. Notify Packet Types:
* A new error value: SERVER_REFLEXIVE_CANDIDATE_ALLOCATION_FAILED
5.13. PEER_PERMISSION Parameter
* Additional port and address added because multiple server reflexive
candidates can be leased
6.2. Opportunistic Mode
* Clarified that anycast and multicast are out of scope
7. IANA Considerations
* Error values are listed also here
Appendix D. Multihoming Considerations:
* new section on future compatibility with possible multihoming extensions
* Some minor clarifications here and there

Title : Native NAT Traversal Mode for the Host Identity
Protocol
Authors : Ari Keranen
Jan Melén
Miika Komu
Filename: draft-ietf-hip-native-nat-traversal-23.txt
Pages : 60
Date: 2017-11-12
Abstract:
This document specifies a new Network Address Translator (NAT)
traversal mode for the Host Identity Protocol (HIP). The new mode is
based on the Interactive Connectivity Establishment (ICE) methodology
and UDP encapsulation of data and signaling traffic. The main
difference from the previously specified modes is the use of HIP
messages for all NAT traversal procedures.
