Ruff v0.16.0 – Significant new updates – 413 default rules up from 59
Ruff v0.16.0 introduces a major expansion of default lint rules, increasing from 59 to 413 rules. This update significantly broadens the scope of static analysis and code style enforcement available out of the box. The release also includes various performance improvements and bug fixes, though specific details are not provided in the source. The change is expected to reduce the need for custom rule configurations for many projects, as the new defaults cover a wider range of common Python coding issues. The source does not specify exact version numbers for dependencies or benchmark comparisons, but the rule count increase is explicitly stated.
Developers using Ruff will benefit from broader default lint coverage, reducing manual configuration.
