v1753
May 21, 2026

Bug fixes and other internal updates.

v1752
May 21, 2026

For data connectors that upload objects to Amazon S3 - including Amazon Redshift, Databricks, the file connector, and Snowflake - to ensure that tags are applied, the IAM user must have s3:PutObjectTagging on the destination S3 bucket. To prevent jobs from failing, when the permission is missing, Structural logs a warning and continues to upload without tags.

v1751
May 21, 2026

For the Text Composition generator, you can now use AI assistance to generate templates. For example, “Set the value to the first 3 characters of the FirstName column followed by the last 3 characters of the LastName column, in all caps”.

v1750
May 20, 2026

Salesforce - GlobalValueSet picklist constraints are now lifted and restored. Managed-package fields are skipped.

Salesforce - Fixed an issue where Tooling API queries might not have returned all records.

By default, self-hosted customers who have not either set up an LLM or opted out of LLM use are connected to Structural’s hosted LLM. This enables self-hosted customers to have immediate access to Structural’s AI-powered features. For existing customers who upgrade to this version, sharing of sample data with the LLM is disabled automatically.

Hosted LLM for self-hosted customers - Structural now provides a hosted LLM for that self-hosted customers can use instead of connecting to their own LLM.

v1749
May 19, 2026

For the Date Truncation and Timestamp Shift generators, you can now optionally configure a fallback generator, to accommodate datetime values that the generator cannot process. The available options are Fail on error (the default), Passthrough, Constant (where you provide the value to use), or Null.

v1748
May 19, 2026

Fixed an issue where subsetting jobs failed when the Passthrough generator was applied manually to columns.

v1747
May 18, 2026

On a self-hosted instance, when you configure the connection to an LLM, you can now provide a specific model name to use.

v1746
May 15, 2026

Bug fixes and other internal updates.

v1745
May 15, 2026

MySQL - Tailscale tunneling is now supported for MySQL.

Fixed an issue where the IBAN generator would throw errors when the source value was not a fully valid IBAN. Validation has been relaxed for non-primary key fields or when consistency is not enabled, allowing a new IBAN to be generated when:

  • The bank code is preserved. The source value no longer needs to be a valid IBAN. However, the bank code is only preserved only if the source contains a valid country code and a bank code of the correct length.

  • The country code is preserved.

  • The country code is missing. When the source value's country code is unknown or missing, the generator now falls back to a randomly selected valid country code.

v1744
May 13, 2026

In the Conditional generator, you can now apply a condition to whatever the current column is. In the application, the option is This field. In the API, you use field_self. You can use this option to define Conditional generator presets that can apply to a wider range of columns.

v1743

v1741
May 13, 2026

Bug fixes and other internal updates.

v1740
May 11, 2026

Added support to use the Structural agent to diagnose datasource connection test failures. For failed tests, an Ask AI prompt allows you to ask an LLM to troubleshoot the issue and suggest next steps.

Controlling AI access to sample data - Added an option to control whether AI features have access to sample data. When true, AI features can retrieve sample data from the workspace source database to improve functionality and output quality. When false, AI features only have access to database schema information. The default value is true.

For self-hosted instances, the option is on the Structural AI Settings page or as the environment setting TONIC_LLM_ENABLE_SAMPLE_DATA. On Structural Cloud, the option is on the Organization Settings page as TONIC_LLM_ENABLE_SAMPLE_DATA.
