Rust 1.98.0 Released
By BIOS Founding Team
The Rust team announced the release of Rust 1.98.0 on August 20, 2026.
The headline addition is a set of 'algebraic' methods on the f32 and f64 floating-point types for addition, subtraction, multiplication, division, and remainder. These let developers opt into optimizations based on the algebraic properties of real numbers (like reordering operations for speed) in the specific cases where that tradeoff against strict IEEE 754 floating-point behavior is acceptable.
The release also updates the documentation for ManuallyDrop with a stable guarantee about certain behavior continuing to be defined (not undefined behavior) going forward, useful for anyone writing unsafe, low-level Rust code that leans on it.
Rust ships a new stable release roughly every six weeks, and each one is free, open source, and built in the open on GitHub, small documentation fixes and testing on release candidates are genuinely useful first contributions if you want to get involved.
