Announcing Rust 1.84.0 | Rust Blog
The Rust team is happy to announce a new version of Rust, 1.84.0. 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 1.84.0.
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!
1.84.0 stabilizes the minimum supported Rust version (MSRV) aware resolver, which prefers dependency versions compatible with the project's declared MSRV. With MSRV-aware version selection, the toil is reduced for maintainers to support older toolchains by not needing to manually select older versions for each dependency.
You can also opt-in by setting package.resolver = "3" in the Cargo.toml manifest file though that will require raising your MSRV to 1.84. The new resolver will be enabled by default for projects using the 2024 edition (which will stabilize in 1.85).
