I would like to propose another option.
4) Add an informational note in the update draft that the codebase on
opus-codec.org has diverged, and may continue to diverge, from the code in
RFC 6716, without breaking normative bitstream compatibility.
This option seems sufficient and lightweight.

Hi,
I just uploaded a new version of the Opus draft. It adds fixes for two
decoder integer wrap-around issues discovered through fuzzing. None of
them is particularly frightening, but they still needed to be fixed. At
this point, I do not expect more fixes to this document -- please let me
know if you think I missed something.
I'm also realizing just how much the "current" codebase on
opus-codec.org has come to differ from the code in RFC6716. This
includes many many fixes and improvements to the encoder and fixed-point
decoder. Since they are not normative bitstream changes, they are not
included in this update draft. I think it would be nice to update the
IETF "reference implementation" of Opus to reflect the improvements.
That being said, I'm not sure what's the best way to do that. I can
think of several options:
1) An (informational?) RFC with updated based64 tarball containing the
newest version
2) A tarball of the new version uploaded as meeting material like the
original testvectors (where would we link to it?)
3) Somehow mirroring the opus-coder.org downloads on the IETF website
There's probably other options too. Any thoughts?
Cheers,
Jean-Marc
