v1869
September 15, 2026

File groups: Fixed an issue where selecting files in quick succession could leave a file with no data preview and suppress the warning that the selected files do not all have the same columns.

When you delete a user who owns workspaces, you no longer have to immediately transfer those workspaces to a new owner. The workspaces are added to the Workspaces Without an Owner tab on Team Settings. From there, an admin can transfer the workspaces to a new owner or delete the workspaces. Other users that were granted access to the workspaces lose their access until the workspace is transferred.

New team permissions, permission sets, and Team Settings page

Global permissions sets are now separated into global permission sets and new team permission sets. The permissions to create workspaces, manage presets, copy workspaces, enable diagnostic logging, manage sensitivity rules, and manage secrets managers are now team permissions. The existing permissions migrate from global to team automatically.

Every organization now has a default team. Organization administrators automatically become the administrators of the organization’s default team.

The new Team Settings page, which is available to team administrators, allows them to manage team and workspace permission sets.

This is in preparation for a future enhancement to allow Enterprise organizations to create multiple teams and to manage resources separately within those teams.

You can now create custom permission sets on Structural Cloud.

v1868
September 15, 2026

Made the following changes to the Finnish Personal Identity Code generator:

  • The generator now preserves uniqueness, and can be used on unique and primary-key columns.

  • The century indicator in each generated code now mirrors the source value instead of being spread evenly across every indicator letter. This ensures that common indicators (+, -, A) remain common, and that rare reform letters only appear when the source uses them.

  • During data generation, Structural warns when the sampled values fall outside of the chosen birth-date range or use indicators that the range cannot represent. Structural drops those rows instead of writing them to the destination.

v1861
September 4, 2026

Aurora (PostgreSQL data connector) - Fixed an issue where PostgreSQL data generation to an Amazon Aurora destination failed on every run after the first when the source database had Aurora's pg_columnmask dynamic data masking extension installed. Structural no longer copies provider-managed extensions into the destination.

v1860
September 3, 2026

The Structural Agent can now describe the configuration of a generator preset for a composite generator such as Regex Mask and JSON Mask. Previously, it could only see that the generator preset existed.

v1859
September 2, 2026

Oracle workspaces now always run on Data Pipeline V2. The option on the Confirm Generation panel to choose between classic flow and Data Pipeline V2 is removed. Existing Oracle workspaces will automatically use the Data Pipeline V2 flow.

Removed the Oracle database-link generation path and the TONIC_ORACLE_DBLINK_ENABLED environment setting. The setting no longer has any effect. You can remove it from your configuration. Database links that exist as objects in your Oracle schema are not affected. Structural still discovers them, and still warns when the destination is missing a link that is referenced by a source synonym.
