Version Details and Security Vulnerabilities

eslint-config-next is the officially supported ESLint configuration for Next.js projects, designed to streamline code quality and consistency within your Next.js applications. Comparing versions 14.2.1 and 14.2.0 reveals subtle but important refinements for developers. Both versions share a foundation of crucial dependencies, including eslint-plugin-react, eslint-plugin-import, and eslint-plugin-jsx-a11y, ensuring robust linting for React components, import statements, and accessibility best practices. They also incorporate @rushstack/eslint-patch for enhanced ESLint compatibility and @typescript-eslint/parser to seamlessly handle TypeScript codebases. The peer dependencies remain consistent, requiring compatible versions of ESLint and TypeScript.

The core difference lies in the updated @next/eslint-plugin-next dependency; version 14.2.1 utilizes @next/eslint-plugin-next@14.2.1 aligning the linter more closely with Next.js v14.2.1, whereas version 14.2.0 uses @next/eslint-plugin-next@14.2.0. This upgrade likely incorporates new or revised linting rules tailored to the latest Next.js features and optimizations. Developers should upgrade to eslint-config-next@14.2.1 to receive the most up-to-date linting guidance and catch potential issues specific to Next.js 14.2.1. If you are using next.js 14.2.0, it means that you can still use eslint-config-next@14.2.0, but bear in mind that if you upgrade next.js version you should upgrade eslint-config-next accordingly. The release date indicates a very recent update showing that the Next.js team actively maintains and improves the linting configuration.
