+author: The Rust Core Team
+---
+
+The Rust team is happy to announce the latest version of Rust, 1.14.0. Rust is a
+systems programming language focused on safety, speed, and concurrency.
+
+As always, you can [install Rust 1.14.0][install] from the appropriate page on our
+website, and check out the [detailed release notes for 1.14.0][notes] on GitHub.
+1230 patches were landed in this release.
+

+
+### What's in 1.14.0 stable
+
+One of the biggest features in Rust 1.14 isn't actually in Rust 1.14: the
+[rustup tool has reached a 1.0 release][rustup], and is now the recomended way
+to install Rust from the project directly. Rustup does a bit more than just
+install Rust:
+
+> rustup installs The Rust Programming Language from the official release
+> channels, enabling you to easily switch between stable, beta, and nightly
+> compilers and keep them updated. It makes cross-compiling simpler with binary
+> builds of the standard library for common platforms. And it runs on all
+> platforms Rust supports, including Windows.
+

+
+We had [a previous post about Rustup][prev] back in May. You can learn more
+about it there, or by checking it out [on
+GitHub](https://github.com/rust-lang-nursery/rustup.rs)
+
+[prev]: https://blog.rust-lang.org/2016/05/13/rustup.html
+
+Another exciting feature is [experimental support for WebAssembly][wasm] as a
+target, `wasm32-unknown-emscripten`. It is still early days, and there's a lot
+of bugs to shake out, so please give it a try and report them! To give you a
+small taste of how it works, one you have [emscripten] installed, compiling
+some Rust code to WebAssembly is as easy as:
+
+```bash
+$ rustup target add wasm32-unknown-emscripten
+$ echo 'fn main() { println!("Hello, Emscripten!"); }' > hello.rs
+$ rustc --target=wasm32-unknown-emscripten hello.rs
+$ node hello.js
+```
+
+[wasm]: https://users.rust-lang.org/t/compiling-to-the-web-with-rust-and-emscripten/7627
+[emscripten]: http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html
+
+The community has been doing intertesting, experimental work in this area: see
+[Jan-Erik's slides] for the workshop he ran at [Rust Belt Rust] for some
+examples, or check out [Tim's example of the classic TodoMVC project][todomvc].
+This implementation builds off of his [webplatform
+crate](https://crates.io/crates/webplatform), which exposes the DOM to Rust.

+
+Speaking of platforms, a large number of platforms have gained additional
+support:
+
+For `rustc`:
+
+* `mips-unknown-linux-gnu`
+* `mipsel-unknown-linux-gnu`
+* `mips64-unknown-linux-gnuabi64`
+* `mips64el-unknown-linux-gnuabi64`
+* `powerpc-unknown-linux-gnu`
+* `powerpc64-unknown-linux-gnu`
+* `powerpc64le-unknown-linux-gnu`
+* `s390x-unknown-linux-gnu`
+
+And for `std`:
+
+* `arm-unknown-linux-musleabi`
+* `arm-unknown-linux-musleabihf`
+* `armv7-unknown-linux-musleabihf`
+
+If you're using one of these platforms, follow the instructions on the website
+to install, or add the targets to an existing installation with
+`rustup target add`.
+
+These platforms are all 'tier 2', please see our page on [platform support] for
+more details.
+
+[platform support]: https://forge.rust-lang.org/platform-support.html
+
+The landing of MIR over the last few releases means that a [number of
+improvements to compile times] have landed, with more coming in the future.
+Exact numbers are hard, as they depend on what code you're compiling, but
+broadly speaking, compile times should be the same or faster.
+
+[numer of improvements to compile times]: https://github.com/rust-lang/rust/blob/master/RELEASES.md#compile-time-optimizations
+
+In the language, one small improvement has landed: support for [RFC 1492]. This small
+additional lets you use `..` in more places. Previously, say you had a struct like this:
+
+```rust
+struct Point {
+    x: i32,
+    y: i32,
+    z: i32,
+}
+```
+
+In any context where you're doing a pattern match, you could use `..` to ignore the
+parts you don't care about. For example:
+
+
+```rust
+let p = Point { x: 0, y: 1, z: 2 };
+
+match p {
+    Point { x, .. } => println!("x is {}", x),
+}
+```
+
+The `..` ignores `y` and `z`.
+
+Consider a similar `Point`, but as a tuple struct:
+
+```rust
+struct Point(i32, i32, i32);
+```
+
+Previously, you could use `..` to ignore all three elements:
+
+```rust
+let p = Point(0, 1, 2);
+
+match p {
+    Point(..) => println!("found a point"),
+}
+```
+
+But you could not use it to only ignore parts of the tuple:
+
+```rust
+let p = Point(0, 1, 2);
+
+match p {
+    Point(x, ..) => println!("x is {}", x),
+}
+```
+
+This was a inconsistency, and so with RFC 1492 stabilized, compiles fine as of
+this release. This applies to more situations than tuples; please see [the
+RFC][RFC 1492] for more details.
+
+[RFC 1492]: https://github.com/rust-lang/rfcs/blob/master/text/1492-dotdot-in-patterns.md
+
+#### Library stabilizations
+
+There have been a number of additions to the standard library, but they don't
+fit into particularly nice categories for this release. Here's the highlights:
+
+* [`println!()`, with no arguments, prints newline][36825].
+  Previously, an empty string was required to achieve the same.
+* [`Wrapping` impls standard binary and unary operators, as well as
+   the `Sum` and `Product` iterators][37356]
+* [Implement `From<Cow<str>> for String` and `From<Cow<[T]>> for
+  Vec<T>`][37326]
+* [Expand `.zip()` specialization to `.map()` and `.cloned()`][37230]
+* [Implement `RefUnwindSafe` for atomic types][37178]
+* [Specialize `Vec::extend` to `Vec::extend_from_slice`][37094]
+* [Don't reuse `HashMap` random seeds][37470]
+* [The internal memory layout of `HashMap` is more cache-friendly, for
+  significant improvements in some operations][36692]
+* [Impl `Add<{str, Cow<str>}>` for `Cow<str>`][36430]

+
+See the [detailed release notes][notes] for more.
+
+#### Cargo features
+
+As for Cargo, [RFC 1721] has been implemented. The motivation for this feature
+is that Cargo can now compile objects for statically linking against the msvcrt
+on the MSVC platform. But, meachnically speaking, this means that Cargo will
+now pass along the values printed by `rustc --print cfg` to build scripts.
+
+[RFC 1721]: https://github.com/rust-lang/rfcs/blob/master/text/1721-crt-static.md
+
+Cargo now works properly [with a read-only `CARGO_HOME`][3259].
+
+Finally, Cargo will [ignore the `panic` configuration for the `test` and
+`bench` profiles][3175]. This is important because the test runner relies on
+panics counting as failing tests, and so with `panic=abort`, a failing test
+would abort the entire test suite.
