 # Changelog
 
+## [1.159.0](https://github.com/googleapis/python-aiplatform/compare/v1.158.0...v1.159.0) (2026-06-30)
+
+
+### ⚠ BREAKING CHANGES
+
+* `datasets.assemble` now returns `tuple[str, Optional[bigframes.pandas.DataFrame]]` (the BigQuery table id without the `bq://` prefix, and the assembled table as a BigFrames DataFrame) instead of the BigQuery URI `str`. By default no DataFrame is loaded (`load_dataframe=False`): the second element is `None`, no BigQuery read is performed, and `bigframes` is not required. Pass `load_dataframe=True` to load the assembled table.
+
+### Features
+
+* Add data_sharing_enabled_provider field (ModelProvider enum) to PublisherModelConfig ([51c4d78](https://github.com/googleapis/python-aiplatform/commit/51c4d78542616d8089db33a108c116da97a8e68b))
