# Ruff v0.5.0

**[Astral](https://daily.dev/sources/astral-sh)** · 10 min read · 0 upvotes · 0 comments

## Summary

Ruff v0.5.0 is released with several breaking changes and improvements. Key changes include: the output format now defaults to `full` (showing code snippets with violations), `--select=ALL` no longer includes deprecated rules, macOS now follows the XDG specification for config file discovery, and various rule remappings merging flake8-async and flake8-trio categories. The E999 syntax error rule is deprecated — syntax errors will always be reported going forward, with a new `showSyntaxErrors` server setting for editor control. The `--statistics` output now shows rule names instead of error messages. Thirty new rules have been stabilized out of preview, and several deprecated CLI commands and settings have been removed.
