 ### Features
 
 - Move the BQ Job link after the job submission instead of job done ([#696](https://github.com/dbt-labs/dbt-bigquery/issues/696))

 ### Fixes
 
+- Support all types of data_type using time ingestion partitioning as previously `date` was failing ([#486](https://github.com/dbt-labs/dbt-bigquery/issues/486))
