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.

* [The `--error-format=json` flag to `rustc` causes it to emit errors
in JSON format][1.7j]. This is an unstable flag and so also requires
the `-Z unstable-options` flag.
* [When running tests with `--test`, rustdoc will pass `--cfg`
arguments to the compiler][1.7dt].
* [The compiler is built with RPATH information by default][1.7rpa].

In other words, the mutable borrow is held through the rest of our example. What
we want is for the mutable borrow to end _before_ we try to call `println!` and
make an immutable borrow. In Rust, borrowing is tied to the scope that the
borrow is valid for. And our scopes look like this:
we want is for the mutable borrow by `y` to end so that the resource can be
returned to the owner, `x`. `x` can then provide a mutable borrow to `println!`.

In the above example, `y` is declared before `x`, meaning that `y` lives longer
than `x`, which is not allowed.

checks are conservative by nature: there are some programs that are actually

this, Rust has a keyword, `unsafe`. Code using `unsafe` has less restrictions
