HighlightsAPI Support for Bulk SuppressionsESLint v10.1.0 introduces API support for the bulk suppressions feature that was previously only available in the CLI.ESLint API consumers, such as IDEs, can now pass the applySuppressions: true option to the ESLint constructor.

The plan for 2025 was to build upon the foundation of language plugins introduced in 2024 and to start the long-awaited core rewrite.

In February, we released official CSS support via the @eslint/css plugin, allowing users to lint their stylesheets with the same familiar configuration system.In May, we were excited to announce that html-eslint had joined the ESLint ecosystem as a language plugin, bringing robust HTML linting to the project. These additions mean that ESLint can now officially be used to lint the “big three” of the web: JavaScript, CSS, and HTML.ESLint’s new CSS and HTML support were
