Rust 1.27 is released on Thursday and builds are available now for testing. Release artifacts are uploaded to dev ([dev-static.rust-lang.org](http://dev-static.rust-lang.org)) currently and will be promoted to prod ([static.rust-lang.org](http://static.rust-lang.org)) this Thursday. The URL is [https://dev-static.rust-lang.org/dist/2018-06-20](https://dev-static.rust-lang.org/dist/2018-06-20)

You can test rustup with

```
RUSTUP_DIST_SERVER=https://dev-static.rust-lang.org rustup update stable

```

Please let us know if you run into any issues! Pending any detected regressions these are likely to be the exact artifacts that we’ll release on Thursday.

You can find the release notes on GitHub as well: [https://github.com/rust-lang/rust/blob/master/RELEASES.md](https://github.com/rust-lang/rust/blob/master/RELEASES.md).

We ran into [some](https://github.com/rust-lang/rust-central-station/issues/50) [troubles](https://github.com/rust-lang/rust-central-station/issues/49) with the issuance of this prerelease, which is the reason for the delay here.
