Rust is a programming language empowering everyone to build reliable and efficient software. + +If you have a previous version of Rust installed via `rustup`, you can get 1.89.0 with: + +```console +$ rustup update stable +``` + +If you don't have it already, you can [get `rustup`](https://www.rust-lang.org/install.html) from the appropriate page on our website, and check out the [detailed release notes for 1.89.0](https://doc.rust-lang.org/stable/releases.html#version-1890-2025-08-07). + +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](https://github.com/rust-lang/rust/issues/new/choose) any bugs you might come across! + +## What's in 1.89.0 stable + +### Explicitly inferred arguments to const generics + +Rust now supports `_` as an argument to const generic parameters, inferring the value from surrounding context: + +```rust +pub fn make_bitset() -> [bool; LEN] { + [false; _] +} +``` + +Similar to the rules for when `_` is permitted as a type, `_` is not permitted as an argument to const generics when in a signature: + +```rust +// This is not allowed +pub fn make_bitset() -> [bool; _] { + [false; LEN] +} +``` + +### Mismatched lifetimes syntax lint + +TC/LANG to write this + +### More x86 target features + +The `target_feature` attribute now supports the `sha512`, `sm3`, `sm4`, `kl` and `widekl` target features on x86. Additionally a number of `avx512` intrinsics and target features are also supported on x86: + +```rust +#[target_feature(enable = "avx512bw")] +pub fn cool_simd_code(/* .. */) -> /* ... */ { + /* ... */ +} + +``` + +### Platform Support + +- [Add new Tier-3 targets `loongarch32-unknown-none` and `loongarch32-unknown-none-softfloat`](https://github.com/rust-lang/rust/pull/142053) + +Refer to Rust’s [platform support page][platform_support_page] for more information on Rust’s tiered platform support. + +### Stabilized APIs + +TODO + +### Other changes + +Check out everything that changed in [Rust](https://github.com/rust-lang/rust/releases/tag/1.89.0), [Cargo](https://doc.rust-lang.org/nightly/cargo/CHANGELOG.html#cargo-189-2025-08-07), and [Clippy](https://github.com/rust-lang/rust-clippy/blob/master/CHANGELOG.md#rust-189). + +## Contributors to 1.89.0 + +Many people came together to create Rust 1.89.0.
