ESLint has evolved its configuration system by introducing the defineConfig() function to simplify type-safe configurations, reintroducing the extends option for easier composition of configurations, and adding the globalIgnores() helper to address confusion around ignore patterns. These updates aim to improve the developer experience based on user feedback while maintaining the flexibility of the flat config system. The new features are also available through the @eslint/config-helpers package for those using older versions of ESLint.
