(Via drafts-eval@iana.org): IESG/Authors/WG Chairs:

The IANA Services Operator has completed its review of draft-nir-cfrg-rfc7539bis-04. If any part of this review is inaccurate, please let us know.

We understand that this document will replace RFC 7539 as the reference for the following AEAD Algorithm registration at https://www.iana.org/assignments/aead-parameters:

29 AEAD_CHACHA20_POLY1305 [this document]

Because this is a "Specification Required" registry, we've asked the designated expert to approve this change request. Because we haven't received his review yet, we're marking this document's IANA review state "Not OK."
