| title: "Announcing Rust 1.6" | ||
| author: The Rust Core Team | ||
| --- | ||
|
|
||
| Hello 2016! We’re happy to announce the first Rust release of the year, 1.6. | ||
| Rust is a systems programming language focused on safety, speed, and | ||
| concurrency. | ||
|
|
||
| As always, you can [install Rust 1.6][install] from the appropriate page on our | ||
| website, and check out the [detailed release notes for 1.6][notes] on GitHub. | ||
| About 1100 patches were landed in this release. | ||
|
|
||
| [install]: http://www.rust-lang.org/install.html | ||
| [notes]: https://github.com/rust-lang/rust/blob/stable/RELEASES.md#version-160-2016-01-21 | ||
|
|
||
| ### What's in 1.6 stable | ||
|
|
||
| This release contains a number of small refinements, one major feature, and | ||
| a change to [Crates.io](https://crates.io). | ||
|
|
||
| #### libcore stabilization | ||
|
|
||
| The largest new feature in 1.6 is that [`libcore`] is now stable! Rust’s | ||
| standard library is two-tiered: there’s a small core library, `libcore`, and | ||
| the full standard library, `libstd`, that builds on top of it. `libcore` is | ||
| completely platform agnostic, and requires only a handful of external symbols | ||
| to be defined. Rust’s `libstd` builds on top of `libcore`, adding support for | ||
| memory allocation, I/O, and concurrency. Applications using Rust in the | ||
| embedded space, as well as those writing operating systems, often eschew | ||
| `libstd`, using only `libcore`. | ||
|
|
||
| [`libcore`]: http://doc.rust-lang.org/nightly/core/ | ||
|
|
||
| `libcore` being stabilized is a major step towards being able to write the | ||
| lowest levels of software using stable Rust. There’s still future work to be | ||
| done, however. This will allow for a library ecosystem to develop around | ||
| `libcore`, but _applications_ are not fully supported yet. Expect to hear more | ||
| about this in future release notes. | ||
|
|
||
| #### Library stabilizations | ||
|
|
||
| About 30 library functions and methods are now stable in 1.6. Notable | ||
| improvements include: | ||
|
|
||
| The `drain()` family of functions on collections. These methods let you move | ||
| elements out of a collection while allowing them to retain their backing | ||
| memory, reducing allocation in certain situations. | ||
|
|
||
| A number of implementations of `From` for converting between standard library | ||
| types, mainly between various integral and floating-point types. | ||
|
|
||
| Finally, `Vec::extend_from_slice()`, which was previously known as | ||
| `push_all()`. This method has a significantly faster implementation than the | ||
| more general `extend()`. | ||
|
|
||
| See the [detailed release notes][notes] for more. | ||
|
|
||
| #### Crates.io disallows wildcards | ||
|
|
||
| If you maintain a crate on [Crates.io](https://crates.io), you might have seen | ||
| a warning: newly uploaded crates are no longer allowed to use a wildcard when | ||
| describing their dependencies. In other words, this is not allowed: | ||
|
|
||
| ```toml | ||
| [dependencies] | ||
| regex = "*" | ||
| ``` | ||
|
|
||
| Instead, you must actually specify [a specific version or range of | ||
| versions][versions], using one of the `semver` crate’s various options: `^`, | ||
| `~`, or `=`. | ||
|
|
||
| [versions]: http://doc.crates.io/crates-io.html#using-cratesio-based-crates | ||
|
|
||
| A wildcard dependency means that you work with any possible version of your | ||
| dependency. This is highly unlikely to be true, and causes unnecessary breakage | ||
| in the ecosystem. We’ve been advertising this change as a warning for some time; | ||
| now it’s time to turn it into an error. | ||
|
