RFC 9851: TLS 1.2 is in Feature Freeze
WHY IT MATTERS
This formalizes the protocol's end-of-life for new features and explicitly rules out post-quantum cryptography support for TLS 1.2, meaning systems requiring PQC must adopt TLS 1.3. Engineers maintaining legacy systems can no longer expect protocol extensions and should plan migrations to TLS 1.3 for future cryptographic requirements.
Written by elseif from the cluster below · every claim links back to a sourceThe three things worth knowing
01
Future changes to TLS 1.2 are limited to urgent security fixes, ALPN Protocol IDs, and TLS Exporter Labels.
02
Post-quantum cryptography will not be specified for TLS 1.2, requiring a move to TLS 1.3 for PQC support.
03
The feature freeze applies only to TLS and does not affect any version of DTLS.
