Version Details and Security Vulnerabilities

eslint-config-next versions 15.4.2 and 15.4.3 offer standardized ESLint configurations tailored for Next.js projects, ensuring consistent code style and best practices. Both versions share a common foundation, including dependencies like eslint-plugin-react, eslint-plugin-import, and eslint-plugin-jsx-a11y for React and accessibility linting. They also leverage @rushstack/eslint-patch to address ESLint compatibility issues. The core difference lies in the version of @next/eslint-plugin-next, which is 15.4.3 in the newer release and 15.4.2 in the older one. This plugin provides Next.js-specific linting rules.

For developers, this means upgrading to 15.4.3 primarily brings updates and improvements within the @next/eslint-plugin-next package itself. Dependency version maintenance is important and the bump to the newer @next/eslint-plugin-next could include fixes for false positives, new and updated rules to promote best practices in Next.js development, or address compatibility issues with newer Next.js features. Examine the changelog for @next/eslint-plugin-next 15.4.3 for detailed insights into these specific enhancements. Keep in mind that both versions specify the same peer dependencies for eslint and typescript, underscoring the need for compatible versions of these core tools. Upgrading ensures you're benefiting from the latest linting rules aligned with Next.js's evolving ecosystem.
