Version Details and Security Vulnerabilities

The eslint-config-next package provides a pre-configured ESLint setup tailored for Next.js projects, ensuring consistent code quality and adherence to best practices. Comparing versions 15.4.0 and 15.3.5, developers will notice a primary difference in the @next/eslint-plugin-next dependency, which has been updated from 15.3.5 to 15.4.0 to stay synchronized with the Next.js framework itself. This update likely includes new or modified linting rules specific to the features and changes introduced in Next.js 15.4. For developers, this means upgrading to eslint-config-next@15.4.0 ensures their linting rules correctly reflect the latest Next.js patterns, potentially highlighting areas where code needs adjustments for optimal performance or compatibility. Both versions share the same peer dependencies, requiring eslint (versions 7.23.0, 8.0.0, or 9.0.0 and newer) and typescript (version 3.3.1 or newer), indicating a consistent core linting environment. Furthermore, there's a slight difference in the unpacked size, with version 15.4.0 being marginally larger (5017 bytes vs 4906 bytes) probably due to the updated @next/eslint-plugin-next package of 15.4 adding rules or other improvements. Finally, the release dates clearly show that version 15.4.0 is the newest one. If you're using Next.js 15.4, upgrading to this corresponding linting configuration is highly recommended to catch potential issues early and maintain code quality as the Next.js ecosystem evolves.
