Hiya,

FWIW, I've updated my code [1] to support draft-06
and verified the new test vectors.

That was pretty easy, but I'd appreciate if we could
call a halt to changes unless those are very important.
And I mean a *halt* and not reduce to one every two
weeks rather than one every few days.

I'll complain again on the TLS list about the velocity
of githubbery and lack of list discussion for changes to
this, ECH/ESNI and the HTTPS RR drafts, so no need for
us to discuss that here;-)

To be clear I include all three drafts when I say "one
every few days."

Cheers,
S.
