+- Workaround for the issue #694. From now all the storage operation options are being passed to the event object. For example when calling the `save` method:
+```js
+user.save({ fields: ["firstName"] });
+```
+The fields option will be available in the event handler.
+```js
+events: {
+  beforeSave(e) {
+    if (
+      e.fields &&
+      e.fields.includes("firstName") &&
+      e.doc.isModified("firstName")
+    ) {
+      // Do something...
+    }
+  }
+}
+```
