Announcing Rust 1.81.0 | Rust Blog
The Rust team is happy to announce a new version of Rust, 1.81.0. 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 1.81.0.
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!
1.81 stabilizes the Error trait in core, allowing usage of the trait in #![no_std] libraries. This primarily enables the wider Rust ecosystem to standardize on the same Error trait, regardless of what environments the library targets.
Both the stable and unstable sort implementations in the standard library have been updated to new algorithms, improving their runtime performance and compilation time.
