RFC 9851: TLS 1.2 is in Feature Freeze
The IETF has officially placed TLS 1.2 into a feature freeze, restricting future changes to urgent security fixes and specific protocol extensions. This move encourages the industry to transition toward the more secure and modern TLS 1.3 standard.
Why it matters
This standardization decision impacts global internet security infrastructure and dictates how developers must handle encrypted communications moving forward.
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). ¶
