Rust Release Changelog - 1.98.0
summary
Rust 1.98.0 ships specific changes: algebraic floating‑point (fast‑math) opt‑in for reordered float ops, two new clippy lints for runtime_symbol_definitions, several tier‑2/3 target promotions, stabilized substr_range despite known false positives, and an unintended derive macro path stabilization that fixes MSRV to 1.96. A p‑critical miscompilation reaches stable but gets fixed. Nightly contains Polonius and the Next Gen Trait Solver, plus restrictions and an experimental function overloading prototype called “splat.”
