Hi, Spencer,

Correct, there is no special treatment of major/minor version octets in the Token Binding protocol.
No presumption of interoperability between clients and servers that support different “minor” versions.
(Similarly, a client that only supports TLS 1.1 cannot connect to a server that only supports TLS 1.2.)
No requirement to support previous “minor” versions.

But it has been convenient to use versions 0.<draft revision> for TB Internet-Draft implementations.
It also seems intuitive that the first standard version will be 1.0.

Cheers,

Andrei

Hi, Andrei,

On Thu, May 10, 2018 at 1:31 PM, Andrei Popov <Andrei.Popov@microsoft.com<mailto:Andrei.Popov@microsoft.com>> wrote:
In the next revision, I will add text to explicitly say that "major" and "minor" are for human convenience only and carry no protocol significance.

So this is only used to tell humans how big a change is, in relative terms?

That works for me (and I had chimed in about major/minor versions during IESG evaluation, so thank you).

Spencer

Thanks,

Andrei

I think naming them "major" and "minor" is misleading, because it doesn't actually mean anything.

Lack of description of how versionning is to be used makes me sad, but I understand that this was discussed in the WG.
