A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Transport Layer Security WG of the IETF.

        Title           : Deprecating TLSv1.0 and TLSv1.1
        Authors         : Kathleen Moriarty
                          Stephen Farrell

   This document [if approved] formally deprecates Transport Layer
   Security (TLS) versions 1.0 [RFC2246] and 1.1 [RFC4346] and moves
   these documents to the historic state.  These versions lack support
   for current and recommended cipher suites, and various government and
   industry profiles of applications using TLS now mandate avoiding
   these old TLS versions.  TLSv1.2 has been the recommended version for
   IETF protocols since 2008, providing sufficient time to transition
   away from older versions.  Products having to support older versions
   increase the attack surface unnecessarily and increase opportunities
   for misconfigurations.  Supporting these older versions also requires
   additional effort for library and product maintenance.

   This document updates the backward compatibility sections of TLS RFCs
   [[list TBD]] to prohibit fallback to TLSv1.0 and TLSv1.1.  This
   document also updates RFC 7525.
