RFC 9720: RFC Formats and Versions
Recent RFCs 2025-01-21
Summary:
In order to improve the readability of RFCs while supporting their
archivability, the definitive version of the RFC Series transitioned
from plain-text ASCII to XML using the RFCXML vocabulary; different
publication versions are rendered from that base document. This
document describes how RFCs are published.
This document obsoletes RFC 7990. This document also updates the
stability policy in RFC 9280.
