+#4038: Add Node.js native ESM support (@giltayar)
+
+Mocha supports writing your test files as ES modules:

+- Node.js only v12.11.0 and above
+- Node.js below v13.2.0, you must set `--experimental-modules` option
+- current limitations: please check our [documentation](https://mochajs.org/#nodejs-native-esm-support)
+- for programmatic usage: see [API: loadFilesAsync()](https://mochajs.org/api/mocha#loadFilesAsync)
+
+**Note:** Node.JS native [ECMAScript Modules](https://nodejs.org/api/esm.html) implementation has status: **Stability: 1 - Experimental**
