------------
uutils follows Rust's release channels and is tested against stable, beta and nightly.
To check which one is the latest stable version of Rust visit [Rust's releases page](https://github.com/rust-lang/rust/releases).
The current oldest supported version of the Rust compiler is `1.22.0`, but `1.20.0` is
known to work as well (test failures when compiling with `1.20.0` are due to the tests
themselves being broken by a change in the compiler).
On Windows, only the nightly version is tested currently.
On both Windows and Redox, only the nightly version is tested currently.
