All,

I have posted an updated stable draft of the IPP System Service v1.1 (SYSTEM) specification to:

    https://ftp.pwg.org/pub/pwg/ipp/wd/wd-ippsystem11-20241011.docx
    https://ftp.pwg.org/pub/pwg/ipp/wd/wd-ippsystem11-20241011.pdf

This version features additional security considerations for X.509 certificates, a description of the mDNS hostname attack with self-signed certificates, and new recommendations that prefer the use of CA-signed certificates (from a local or public CA).
