Rust Coreutils 0.8.0 Release:

We are excited to announce the release of Rust Coreutils 0.8.0 — a major release featuring significant performance gains across core utilities, expanded WebAssembly (WASI) support with a brand-new online playground, and continued hardening against edge-case panics, /dev/full aborts and start of a large-scale migration from nix to rustix** for lower-level syscall safety!
