Use of TLS 1.3, which fixes some known deficiencies in TLS 1.2, is growing.
This document specifies that no changes will be approved for TLS 1.2 outside of
urgent security fixes (as determined by TLS Working Group consensus), new TLS
Exporter Labels, and new Application-Layer Protocol Negotiation (ALPN) Protocol
IDs. This applies to TLS only; it does not apply to DTLS (in any DTLS version).
This document is a product of the Transport Layer Security Working Group of the
IETF.
