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.
