Davi, The introduction of IOAM namespaces was the big addition and came with version 4 of the draft. Since then, some other (small) modifications were also added here and there.
Last time I talked to Shwetha during IETF, she told me it was planned to update vpp/ioam to a more recent version of the draft (i.e., adding support for IOAM namespaces). Now that the draft is mature, you should see updates soon (both for kernel and vpp). AFAIK, HbH options are already up to date (maybe not all?). Only the very last version of the draft (version 7) introduces a change on Trace Option's bitfield, which causes a reordering of options (mainly for opaque snap and csum complement options). That's the same for my kernel implementation, which is not yet up to date with version 7 (will update it ASAP). Things are evolving from a draft point of view, which will ease interoperability tests between kernel & vpp (it's on the todo list).
