v1748

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.

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.
