2. Changes since IETF 96 Update authors information.
Add Acee Lindem and Ing-Wher Chen (Helen) as authors for the drafts.
Update contacts information for both drafts and models.

3. Changes since IETF 96
Consistent usage of ’enable’ as node identifiers and set default.
Rename candidate-disabled to candidiate-enable and set the default value to TRUE.
Rename node identifiers that end with 'enabled' to 'enable'.
Set the default value of routing/…/ospf/instance/areas/area/interfaces/interface/fast-reroute/lfa/enable (previously named 'enabled') to FALSE.
Set the default value of routing/…/ospf/instance/areas/area/interfaces/interface/fast-reroute/remote-lfa/enable (previously named 'enabled') to FALSE

4. Changes since IETF 96 OSPF Timers.
Change hello-timer and wait-timer unit to seconds.
Update hello-timer, dead-timer and wait-timer descriptions.
Add 'dead-timer' to routing-state/…/ospf/instance/areas/area/interfaces/interface/neighbors/neighbor.

5. Changes since IETF 96 OSPF interval.
Adjust range specifications from 'transmit-delay', 'dead-interval', and 'retransmit-interval' in routing/…/ospf/instance/areas/area/interfaces/interface.
Change the type of routing/…/ospf/instance/areas/area/interface/interface/dead-interval to uint32 to match RFC2328 Appendix A.3.2.

6. Changes since IETF 96 Virtual link cleanup.
Remove 'mtu-ignore' and 'prefix-suppression' from virtual-link configuration.

7. Changes since IETF 96 New type for bandwidth.
Add IEEE bandwidth type ieee-bandwidth and update all TE bandwidth fields to use it.
Intermediate solution till ietf-routing-types.yang is ready.

8. Changes since IETF 96 LSA header bit. Add Nt-bit to OSPFv2 router LSA.
Remove L-bit from OSPFv2 router LSA.

9. Changes since IETF 96 Fix compilation errors when using Confd.
Fix xpath reference errors to operation-mode and area-type.

10. Changes since IETF 96 Static neighbor ID for IPv4 and IPv6
Rename ospf/instance/areas/area/interfaces/interface/static-neighbors/neighbor/address to 'identifier' with type inet:ip-address

11. Changes since IETF 96 OSPF SR.
Extract OSPF SR into draft-ietf-ospf-sr-yang-00.txt.
Update ietf-ospf-sr.yang to use ietf-segment-routing-common.

12. Current Status
Functionality complete for both config and operation states.
Implementations.

13. Next Steps Use ietf-routing-types.yang when available.
Some minor fixes.
Ready for last call afterwards.
