RFC 8996
The official document that declares the old TLS 1.0 and 1.1 protocols obsolete and unsafe to use.
RFC 8996 formally deprecates TLS versions 1.0 and 1.1, telling implementers to stop supporting them because of known weaknesses. Following it means disabling those old versions by default so connections only use modern, secure TLS. Citing 'disabled by default per RFC 8996' signals compliance with current security guidance.
