+- **Breaking:** the datasets API and all related types, following their removal
+  from the Hotdata OpenAPI spec. This drops the `datasets_api` module and the
+  `client.datasets()` resource handle; every dataset model

+  `UpdateDatasetRequest`/`UpdateDatasetResponse`, `ListDatasetsResponse`,
+  `ListDatasetVersionsResponse`, `RefreshDatasetResponse`, `DatasetSummary`,
+  `DatasetVersionSummary`, `DatasetSource` and its `*OneOf*` variants,
+  `InlineDatasetSource`, `SavedQueryDatasetSource`, `SqlQueryDatasetSource`,
+  `UploadDatasetSource`, `UrlDatasetSource`, `InlineData`, `ColumnTypeSpec`);
+  and the dataset-related `JobType` variants (`DatasetRefresh`,
+  `CreateDatasetIndex`).
