RFC 9851: TLS 1.2 is in Feature Freeze
Summary
RFC 9851 states TLS 1.2 will not receive changes outside urgent security fixes, new TLS Exporter Labels, and new ALPN IDs. It clarifies that the restrictions apply to TLS only, and TLS 1.3 is the focus for post-quantum and hybrid algorithms. The document also covers IANA considerations and security implications for deployments.
