Refined the Hostname generator output. This is a consistency breaking change.

In the workspace Schema Changes settings, Structural now preserves the state of the Automatically apply generators setting under Do not block.

For post-job scripts, the Enable Warnings toggle is now enabled by default.

SQL Server - SQL Server data generation now always uses the Data Pipeline V2 process. It does not support the previous process. The Confirm Generation panel no longer allows you to choose which process to use.

v1648
February 13, 2026

Fixed an issue where the PostgreSQL driver defaults for data source connection pool sizes could, for some deployment configurations, introduce server-side connection leaks for the Structural application database. To mitigate the leaks, explicit settings are now applied.

v1647
February 12, 2026

A new environment setting, TONIC_LLM_ENABLE_ENHANCED_RECOMMENDATIONS_SAMPLE_DATA, determines whether LLM-based sensitivity scans include sample data. Using sample data improves the quality of the detections. When set to false, only schema information is sent. The default value is true.

Structural Cloud users who have the Account Admin permission set can change this setting from the new Organization Settings tab under Structural Settings.

Amazon Redshirt - For subsetting, added support for date/time primary keys and fixed table identification issues.

For self-hosted instances, Structural telemetry now includes database schema information.

SQL Server - SQL Server data generation now always uses the Data Pipeline V2 process. It does not support the previous process. The Confirm Generation panel no longer allows you to choose which process to use.

v1642
February 10, 2026

Fixed an issue where when a workspace was configured to automatically apply generators for schema changes, and you changed the top-level schema change management to block on some or all schema changes, you could not save the workspace configuration.

LLM-based sensitivity detection on Structural Cloud

On Structural Cloud, sensitivity scans now include more comprehensive sensitivity type identifications that are driven by LLM inference. The LLM-based sensitivity detection analyzes schema metadata and a small set of 3 or fewer data samples, which allows Structural to provide better type identification and expanded generator suggestions.
