 As of **v27**, this project has been updated to use the [GAS V8 runtime](//developers.google.com/apps-script/guides/v8-runtime) with [Typescript](//www.typescriptlang.org/docs/handbook/release-notes/typescript-3-9.html)! This introduces a number of [breaking changes](#breaking-changes). Scripts utilizing the old Rhino runtime must use **v26**.
 
+## Fork details
+In this fork, I added `BatchWrite` functionality both `atomic` and `non-atomic` options. The original library id is `1VUSl4b1r1eoNcRWotZM3e87ygkxvXltOgyDZhixqncz9lQ3MjfT1iKFw`.
+
+Since this is a new deployment on GAS, the versioning is reset to `v1`.
+
+### Future work
+- update the documentation for the `BatchWrite` operations.
+- Add full transaction support
+
+### Changelog
+#### V1
