+
+We're delighted to announce that Data Controller now supports **Snowflake** as a data modification target!  This means you can use Data Controller's full suite of governed data editing, approval workflows, and audit trail capabilities directly against your Snowflake tables — on both SAS 9 and SAS Viya.
+
+## What This Means for You
+
+If your organisation stores data in Snowflake, you can now:
+
+- **Edit** Snowflake table data through the familiar Data Controller interface
+- **Submit** changes for review and approval before they are applied
+- **Audit** every change with a complete, tamper-evident history
+
+No more uncontrolled spreadsheet uploads or direct database edits — every modification goes through the same governed process you rely on for your SAS datasets.
+
+## Implementation Details
+
+On SAS Viya, the library should be assigned in the autoexec.  On SAS 9, Snowflake library assignments can come from the autoexec, or from **SAS Metadata**.  Simply register your Snowflake library in SMC or SAS DI Studio as you normally would, and Data Controller will pick it up automatically.
+
+Both the `SNOW` (alias) and `SASIOSNF` engines are supported.
+
+
+## Native Passthrough SQL
+
+Under the hood, Data Controller uses **native passthrough SQL** to interact with Snowflake.  This means:
+
+- Modifications are pushed directly to Snowflake using its own SQL dialect
+- The target table does **not** need to be indexed (but must unique on its primary key)
+- Maximum performance and compatibility with Snowflake's architecture is assured
+
+## Getting Started
+
+Snowflake support is available out of the box — no additional configuration is required beyond your existing Snowflake library assignment in SAS.  More details on Data Controller are available in the [documentation](https://docs.datacontroller.io).
