www.rust-lang.orgLatest stable Rust: 1.99.1, released (release notes). 36 stable releases since 8 Feb 2024.
42 daysbetween every minor release since 1.76.0, 24 releases in a row.
minor release, labelled 1.n12 point releases1.100.0, due 12 Nov 2026
Rust 1.99.0 shipped on 1 October 2026. It is the 24th minor release since 1.76.0 in February 2024, and all 23 gaps between them were exactly 42 days. If the train keeps time, 1.100.0 arrives on 12 November.
The surprises are in the 12 point releases. The latest, 1.99.1 on 16 October, fixed a miscompilation of FFI functions returning bool on x86_64. It also fixed rust-lld on macOS, 13 months after rust-lld became the default linker on x86_64 Linux.
As of 24 October 2026.
The 2024 Edition went stable in 1.85.0 on 20 February 2025. A month later 1.85.1 had to fix the edition's doctest merging.
let chains followed in 1.88.0 on 26 June 2025, and only for code on the 2024 edition.
1.77.2 shipped the fix the same day. On 4 September 2024 the project announced CVE-2024-43402: batch file arguments still were not escaped when the file name ended in whitespace or periods. 1.81.0 closed it the next day.
So the fix needed its own CVE, five months later.
Stable took 16 months. 1.90.0 on 18 September 2025 made lld the default on x86_64-unknown-linux-gnu.
rust-lld still gets fixes in point releases. 1.99.1 added a missing rpath for libLLVM on macOS.
Async closures were stabilized in 1.85.0 on 20 February 2025, in the same release as the 2024 Edition.
The promotion shipped in 1.82.0 on 17 October 2024. In 1.93.1 on 12 February 2026 a revert fixed file descriptor leaks on wasm32-wasip2.

Run rustup update to move every installed toolchain to its newest release, then rustc --version to confirm. Stable ships every six weeks; to hold a project on one release, check a rust-toolchain.toml into its root.

Rust 2024 became stable in 1.85.0 on 20 February 2025. Migrate with cargo fix --edition, then set edition = "2024" in Cargo.toml. Editions are per crate, so a 2024 crate can depend on 2015, 2018 and 2021 crates and the other way around.

cargo fmtThe change most likely to surprise you is in return-position impl Trait: in Rust 2024 it captures every in-scope generic parameter, lifetimes included. Where a function must not capture one, list what it does capture with a use<..> bound, available since 1.82 in every edition.

wasm32-wasi is gone: Rust 1.84.0 (9 January 2025) removed it. Use wasm32-wasip1 for WASI 0.1 (the same target, renamed in 1.78) or wasm32-wasip2 for WASI 0.2 and the component model. wasm32-wasip2 reached tier 2 in 1.82.0 on 17 October 2024.
rustup target add wasm32-wasip2
cargo build --target wasm32-wasip2wasm32-wasi with wasm32-wasip1 everywhere it appears: CI scripts, .cargo/config.toml, rust-toolchain.toml targets and cfg checks on the target name.Since Rust 1.81 the compiler warned on every use of wasm32-wasi, so a build log from 1.81 to 1.83 shows where the old name still appears.
