+### ESM Support for Extensions
+
+The NodeJS extension host now supports extensions that use JavaScript-modules (ESM). All it needs is the `"type": "module"`-entry in your extension's `package.json`-file. With that the JavaScript code can use `import`- and `export`-statements, including the special module `import('vscode')`. Find a sample here: https://github.com/jrieken/vscode-esm-sample-extension.
+
+Please note that ESM support isn't for the web worker extension host yet. There are some technical challenges that need to overcome first and we'll post updates on https://github.com/microsoft/vscode/issues/130367
