IANA Registry Updates for TLS and DTLS
Abstract
This document describes a number of changes to TLS and DTLS IANA
registries that range from adding notes to the registry all the way
to changing the registration policy. These changes were mostly
motivated by WG review of the TLS- and DTLS-related registries
undertaken as part of the TLS 1.3 development process.
This document updates the following RFCs: 3749, 5077, 4680, 5246,
5705, 5878, 6520, and 7301.

RFC 8447 IANA Registry Updates for TLS and DTLS August 2018
1. Introduction
Per this document, IANA has made changes to a number of IANA
registries related to Transport Layer Security (TLS) and Datagram
Transport Layer Security (DTLS). These changes were almost entirely
motivated by the development of TLS 1.3 [RFC8446].
The changes introduced by this document range from simple, e.g.,
adding notes, to complex, e.g., changing a registry's registration
policy. Instead of listing the changes and their rationale here in
the introduction, each section provides rationale for the proposed
change(s).
This document proposes no changes to the registration policies for
TLS Alerts [RFC8446], TLS ContentType [RFC8446], TLS HandshakeType
[RFC8446], and TLS Certificate Status Types [RFC6961] registries; the
existing policies (Standards Action for the first three; IETF Review
