+* the `generation` parameter is deprecated in `GoogleCloudStorageHook.delete` and `GoogleCloudStorageHook.insert_object_acl`.
 
 Updating to `google-cloud-storage >= 1.16` changes the signature of the upstream `client.get_bucket()` method from `get_bucket(bucket_name: str)` to `get_bucket(bucket_or_name: Union[str, Bucket])`. This method is not directly exposed by the airflow hook, but any code accessing the connection directly (`GoogleCloudStorageHook().get_conn().get_bucket(...)` or similar) will need to be updated.
