+### Notable Changes
+
+#### Automatically detect and run ESM syntax
+
+The new flag `--experimental-detect-module` can be used to automatically run
+ES modules when their syntax can be detected. For “ambiguous” files, which are
+`.js` or extensionless files with no `package.json` with a `type` field, Node.js
+will parse the file to detect ES module syntax; if found, it will run the file
+as an ES module, otherwise it will run the file as a CommonJS module.
+The same applies to string input via `--eval` or `STDIN`.
+
+We hope to make detection enabled by default in a future version of Node.js.
+Detection increases startup time, so we encourage everyone — especially package
+authors — to add a `type` field to `package.json`, even for the default
+`"type": "commonjs"`. The presence of a `type` field, or explicit extensions
+such as `.mjs` or `.cjs`, will opt out of detection.
+
