External OAuth and configurable scopes for MCP servers (General availability)
Two new hierarchical parameters let you bind MCP servers to your organization’s existing identity provider (IdP) and control which OAuth scopes MCP clients discover. This enables MCP clients such as Claude, Cursor, and ChatGPT to authenticate against your corporate IdP instead of Snowflake OAuth.
Variant and Variant shredding are now generally available
Variant is now generally available . Variant is a flexible data type for semi-structured data that delivers structured-like query performance through Variant shredding, which is also generally available.
Transactions are now generally available
Transactions that write to Unity Catalog managed Delta tables are now generally available. Group multiple SQL statements across one or more tables into a single atomic transaction using BEGIN ATOMIC ... END; or BEGIN TRANSACTION; ... COMMIT; syntax. All changes succeed together or roll back together, ensuring data consistency across your operations.
Email notifications for expiring service principal tokens are now generally available
Databricks now automatically sends an email notification when a service principal token is set to expire within seven days. Because service principals don't have their own mailboxes, Databricks sends these notifications to workspace admins.
Role-based access control (RBAC) is in Public Preview
Role-based access control (RBAC) is now in Public Preview. RBAC lets users assume a role in Databricks using only that role's permissions for the duration of the session instead of their own accumulated permissions. This enables exclusive access.
Governance Hub is in Beta
Governance Hub is in Beta . Governance Hub is a centralized, account-level UI in the account console for monitoring governance across your Databricks account. It provides a unified view of data health and coverage, AI usage and spend, and cost drivers, with prioritized insights and recommendations. All views respect existing permissions.
