I have reviewed this document as part of the security directorate's 
ongoing effort to review all IETF documents being processed by the 
IESG.  These comments were written primarily for the benefit of the 
security area directors.  Document editors and WG chairs should treat 
these comments just like any other last call comments.

The summary of the review is READY.

It's a short, but comprehensive document deprecating use of TLS v1.1 and v1.2, and DTLS v1.0. This deprecation avoids reliance upon weak ciphersuites/cryptographic primitives, and should help focus implementations on a reduced number of requirements (i.e. no fall-back to weak protocols), which ideally results in fewer implementation errors.
