LOONGARCH GETS NATIVE MATH OPS AS CLIPPY TIGHTENS LINT RULES

Rust's compiler-builtins now dispatch LoongArch hardware floating-point instructions for fma, rint, and sqrt, while Clippy's mut_mut lint gets a complete rewrite to handle syntax context switches correctly.

The compiler-builtins team shipped architecture-specific implementations that let LoongArch systems execute three critical math operations directly on hardware instead of falling back to software emulation [1]. This is the kind of incremental platform support that compounds into measurable performance gains across the ecosystem. Meanwhile, Clippy's mut_mut lint got a full rewrite [2] that removes unnecessary node tracking and block visitors while fixing how it handles syntax context switches, though the team notes span suggestions still need refinement [2]. Over at crates.io, the infrastructure team is keeping dependencies current with prettier now at v3.9.4 [3], vite at v8.1.0 [4], and typescript-eslint at v8.62.1 [5], all routine but necessary updates that keep the registry's frontend ship-shape. The athena ecosystem saw five crate updates across pipelines, rights, typesense, wss, and gateway [6][7][8][9][10], suggesting active development on that subsystem.
