+
+Add a default `languageOptions.parserOptions` to the `recommended` flat config presets. This prevents the `sourceType 'module' is not supported when ecmaVersion < 2015` error when no custom parser options are provided.
+
+For existing users who are already using the `recommended` flat config presets while providing custom parser options, make sure your custom parser options come after the presets to prevent yours from being overridden:
+
+```js
+// eslint.config.js
+import eslintPluginImportX from 'eslint-plugin-import-x'
+
+export default [
+  js.configs.recommended,
+  eslintPluginImportX.flatConfigs.recommended,
+  // Always put your custom language options and parser options after the presets
+  {
+    languageOptions: {
+      ecmaVersion: 'latest',
+      sourceType: 'module',
+      parserOptions: {
+        ecmaVersion: 'latest',
+        sourceType: 'module',
+      },
+    },
+  },
+]
+```
