# Rust release history and what changed since 2024

Source page: https://dev-news.anonyfox.com/rust/

Every Rust release since January 2024 from the rust-lang/rust GitHub releases, and what happened to the Rust stories dev-news covered back then.

## Where it stands (2026-10-24)

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.
