BigQuery ML now supports the DROP MODEL DDL statement for deleting models.

May 6, 2019

BigQuery ML IAM permissions are now available. These permissions take effect on June 6, 2019. Customers with custom roles should migrate to these permissions no later than June 6. Pre-defined IAM roles and primitive roles are not impacted by this change.

April 10, 2019

BigQuery ML now supports the k-means model type for clustering and customer segmentation.

April 4, 2019

During the beta period, Table permissions were automatically applied to models for custom IAM roles. BigQuery ML will begin enforcing several new IAM permissions on June 6, 2019. Customers who used custom IAM roles during the beta period must reconfigure these roles to use the new BigQuery ML permissions. This change will enable you to manage Models permissions separately from BigQuery ML Table permissions. You can begin redefining your custom roles by the end of April, 2019 when the permissions are released. Pre-defined IAM roles and primitive roles are not impacted by this change.
