Ruff v0.1.0 has been released, marking a major stabilization milestone for the fast Python linter written in Rust. Key changes include a new preview mode for unstable features (replacing the old nursery concept), fix safety levels that distinguish between safe and unsafe auto-fixes (with only safe fixes applied by default), and a formal versioning policy using minor versions for breaking changes and patch versions for bug fixes. Ruff now supports over 700 lint rules and has moved its documentation to docs.astral.sh.
