Highlights include:
- Initial support formatting f-strings (in
--preview
). - Support for overriding arbitrary configuration options via the CLI through an expanded
--config
argument (e.g.,--config "lint.isort.combine-as-imports=false"
). - Significant performance improvements in Ruff's lexer, parser, and lint rules.
