<t>This document updates the changes to the TLS and DTLS IANA registries
made in RFC 8447. It adds a new value value, "D" for discouraged discouraged,
to the Recommended "Recommended" column of the selected TLS registries and
adds a "Comment" column to all active registries that do not
already have a "Comment" column. Finally, it updates the
registration request instructions.</t>

      <name>Updating "Recommended" Column's Values</name>
      <t>The instructions in this document update the Recommended "Recommended" column,
originally added in <xref target="RFC8447"/> to add a third value, "D",
indicating that a value is "Discouraged". discouraged. The permitted values
of the "Recommended" column are:</t>
      <dl>
        <dt>Y:</dt>
        <dd>
          <t>Indicates that the IETF has consensus that the
  item is <bcp14>RECOMMENDED</bcp14>. This only means that the associated
  mechanism is fit for the purpose for which it was defined.
  Careful reading of the documentation for the mechanism is
  necessary to understand the applicability of that mechanism.
  The IETF could recommend mechanisms that have limited
  applicability,
  applicability but will provide applicability statements that
  describe any limitations of the mechanism or necessary constraints
  on its use.</t>
        </dd>
        <dt>N:</dt>
        <dd>
          <t>Indicates that the item has not been evaluated by
  the IETF and that the IETF has made no statement about the
  suitability of the associated mechanism. This does not necessarily
  mean that the mechanism is flawed, only that no consensus exists.
  The IETF might have consensus to leave an items item marked as "N" on
  the basis of its the item having limited applicability or usage constraints.</t>
        </dd>
        <dt>D:</dt>
        <dd>
          <t>Indicates that the item is discouraged. This marking could be used to identify
  mechanisms that might result in problems if they are used, such as
  a weak cryptographic algorithm or a mechanism that might cause
  interoperability problems in deployment. When marking a registry entry as
  “D”,
  "D", either the References "Reference" or the Comments Column "Comment" column <bcp14>MUST</bcp14> include sufficient
  information to determine why the marking has been applied. Implementers and
  users <bcp14>SHOULD</bcp14> consult the linked references associated with the item to
  determine the conditions under which the item <bcp14>SHOULD NOT</bcp14> or <bcp14>MUST NOT</bcp14> be used.</t>
        </dd>
      </dl>
      <t>Setting a value to "Y" or "D" or transitioning the value from "Y" or "D" in the "Recommended" column requires
IETF Standards Action with Expert Review or IESG Approval <xref target="RFC8126"/>. Not all items defined
in Standards Track RFCs need to be set
to "Y" or "D". Any item not otherwise specified is set to "N". The column is
blank for values that are unassigned or reserved unless specifically set.</t>
      <section anchor="rec-note">
        <name>Recommended Note</name>
        <t>Existing registries have a note on the meaning of the Recommended "Recommended" column. For the
registries discussed in the subsequent sections sections, this note is updated
with a sentence describing the "D" value as follows:</t>
        <dl>
          <dt>Note:</dt>
          <dd>
            <t>If
        <blockquote>
          <t>Note: If the "Recommended" column is set to "N", it does not necessarily mean
that it is flawed; rather, it indicates that the item either has not
been through the IETF consensus process, has limited applicability, or
is intended only for specific use cases.  If the "Recommended" column
is set to "D" "D", the item is discouraged and <bcp14>SHOULD NOT</bcp14> or <bcp14>MUST NOT</bcp14> be used,
depending upon the situation; consult the item’s item's references for clarity.</t>

Even though this registry does not require a specification, the
designated expert <xref target="RFC8126"/> will strongly encourage registrants
to provide a link to a publicly available specification. An
Internet-Draft (that is posted and never published as an RFC)
or a document from another standards body, industry consortium,
university site, etc. are is suitable for these purposes.
The expert may provide more in-depth reviews, but their approval
should not be taken as an endorsement of the exporter label.  The
expert also verifies that the label is a string consisting of
printable ASCII characters beginning with "EXPORTER".  IANA <bcp14>MUST</bcp14>
also verify that one label is not a prefix of any other label.
For example, labels "key" or "master secretary" are forbidden.</t>

            <t>This document formally deprecates Transport Layer Security (TLS) versions 1.0 (RFC 2246) and 1.1 (RFC 4346). Accordingly, those documents have been moved to Historic status. These versions lack support for current and recommended cryptographic algorithms and mechanisms, and various government and industry profiles of applications using TLS now mandate avoiding these old TLS versions. TLS version 1.2 became the recommended version for IETF protocols in 2008 (subsequently being obsoleted by TLS version 1.3 in 2018), providing sufficient time to transition away from older versions. Removing support for older versions from implementations reduces the attack surface, reduces opportunity for misconfiguration, and streamlines library and product maintenance.</t>
            <t>This document also deprecates Datagram TLS (DTLS) version 1.0 (RFC 4347) but not DTLS version 1.2, and there is no DTLS version 1.1.</t>
