+### BREAKING CHANGES
+
+* ES6 Support - To avoid any incompatibilities between the source of `e2e` tests (ES6) and the source of the application (ES5), we recommend to exclude the `e2e` folder from the application's `tsconfig.json` file: `exclude": [ "e2e" ]`.
+
+#### Migration Steps
+
+Update the `e2e/tsconfig.json` file:
+
+Before:
+```
+{
+    "compilerOptions": {
+        "module": "commonjs",
+        "target": "es5",
+        "experimentalDecorators": true,
+        "emitDecoratorMetadata": true,
+        "importHelpers": true,
+        "types": [
+            "node",
+            "mocha",
+            "chai"
+        ],
+        "lib": [
+            "es6",
+            "dom"
+        ]
+    }
+}
+```
+
+After:
+```
+{
+    "compilerOptions": {
+        "module": "commonjs",
+        "target": "es6",
+        "experimentalDecorators": true,
+        "emitDecoratorMetadata": true,
+        "importHelpers": false,
+        "types": [
+            "node",
+            "mocha",
+            "chai"
+        ],
+        "lib": [
+            "es2015",
+            "dom"
+        ]
+    }
+}
+```
