ESLint v10.0.0 will drop support for Node.js versions below v20.19.0 and completely remove the deprecated eslintrc configuration system in favor of flat config. Major changes include updated Program AST node range coverage, removal of deprecated rule context members and SourceCode methods, JSX reference tracking, and a new configuration file lookup algorithm starting from the linted file. The alpha release is expected in November 2025, with the final release targeted for January 2026.
