🤖 I have created a release beep boop

1.159.0 (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.
