 ## Installation
 In the Google online script editor, select the `Resources` menu item and choose `Libraries...`. In the "Add a library" input box, enter **`1VUSl4b1r1eoNcRWotZM3e87ygkxvXltOgyDZhixqncz9lQ3MjfT1iKFw`** and click "Add." Choose the most recent version number.

 ## Quick start
 #### Creating a service account
 The easiest way to use this library is to create a Google Service Account for your application and give it read/write access to your datastore. Giving a service account access to your datastore is like giving access to a user's account, but this account is strictly used by your script, not by a person.

+
+  This is because this library has been updated to utilize the new [V8 Engine](https://developers.google.com/apps-script/guides/v8-runtime), and classes are not supported in the Rhino Engine.
+  You can either:
+    1. [Migrate your script to use V8](https://developers.google.com/apps-script/guides/v8-runtime/migration), or
+    1. Use the last Rhino version of this library (**v26**).
+
+
 ### Breaking Changes
-* **v27:** Library rewritten with Typescript and Prettier.
-  * Query function names have been capitalized (`Select`, `Where`, `OrderBy`, `Limit`, `Offset`, `Range`).
-  *  **All functions return `Document` or `Document[]` types directly from Firebase. Use `document.obj` to extract the raw object.**
-  *  Undo breaking change from v23. `document.createTime` and `document.updateTime` will remain as timestamped strings. However `document.created`, `document.updated`, and `document.read` are Date objects.
-* **v23:** When retrieving documents the createTime and updateTime document properties are JS Date objects and not Timestamp Strings.
-* **v16:** **Removed:** `createDocumentWithId(documentId, path, fields)`
