Amanda and Zahed,

Thank you for the updates: everything looks as expected.

We have updated the AUTH48 status page to mark IANA’s completion and record 
Zahed’s approval and moved this document to AUTH48-DONE to await the AUTH48 
completions of RFCs-to-be 9626 and 9627.

 Please see the AUTH48 status page for all documents here:
  https://www.rfc-editor.org/auth48/C324

Thank you.

RFC Editor/mf
