Announcing Rust 1.83.0 | Rust Blog

The Rust team is happy to announce a new version of Rust, 1.83.0. Rust is a programming language empowering everyone to build reliable and efficient software.

If you don't have it already, you can get rustup from the appropriate page on our website, and check out the detailed release notes for 1.83.0.

If you'd like to help us out by testing future releases, you might consider updating locally to use the beta channel (rustup default beta) or the nightly channel (rustup default nightly). Please report any bugs you might come across!
