+
+### ⚠ BREAKING CHANGES
+
+* The udfs submodule has been removed from the BQ submodule. You should now invoke it separately.
+* Some output values were changed and/or removed entirely.
+* Dataset access can now be managed via this module. By default the module now grants project owners the `bigquery.dataOwner` role (including on existing datasets). See the migration guide for details.
+* The minimum Google provider version has been
+updated to 3.0.
