The Rust Core Team has announced release of new Rust version, 1.6. Rust is a systems programming language focused on safety, speed, and concurrency.
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.
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.
