 Version 1.7.0 (2016-03-03)
 ==========================
 
-Language
---------
-
-* Soundness fixes to the interactions between associated types and
-  lifetimes, specified in [RFC 1214], [now generate errors][1.7sf] for
-  code that violates the new rules. This is a significant change that
-  is known to break existing code, so it has emitted warnings for the
-  new error cases since 1.4 to give crate authors time to adapt. The
-  details of what is changing are subtle; read the RFC for more.
