The below has a number of clarifications in the floating point area =
(specifically, NaNs), not all of which made it into the -03 for the IETF =
120 cutoff.

It also includes a PR that moves Application Profiles to an appendix and =
deemphasizes them in the body text.  This should reduce confusion that =
CDE is only complete with an Application Profile on top of it.  =
(Unfortunately, moving around text like this also makes it harder to see =
the changes in the diff linked to below =E2=80=94 looking at the source =
changes [1] can be easier as the move was based on a kramdown-rfc trick =
with no physical move of text.)

As our meeting is on Friday, I hope we all do have some time to look at =
the update.

(I=E2=80=99ll also submit a clerical update of draft-bormann-cbor-det, =
which hasn=E2=80=99t really changed since March.  You maybe do want to =
have a look at the initial draft draft-bormann-cbor-numbers [2] for a =
more general look at numbers in CBOR.)
