We have submitted this updated version of the timestamp capability
negotiation draft.

The main difference to the previous draft is a more clear-cut
differentiation between common and version-specific contents, and a
change in the version 0 fields to simplify decoding and differentiation
against an IEEE 754 float representations to prevent implementation
bugs.

Furthermore, we want to discuss the findings of an extensive
investigation around the prevalence of <SYN> && TSecr != 0 at IETF82,
and possible mitigation. These are not yet part of this draft.

Best regards,
   Richard
