Ruff v0.16.0 – Significant new updates – 413 default rules up from 59 | Hacker News

Ruff v0.16.0 was released with a major expansion of enabled default lint rules, jumping from 59 to 413.

The change has sparked debate over how much automated style enforcement should shape Python code and developer workflow.

Supporters say stronger defaults can reduce PR back-and-forth and improve consistency in CI/CD and pre-commit checks.

The release underscores Ruff’s push toward more opinionated, automated code quality enforcement, similar to tools like Black, Flake8, and Pylint.
