New setup wizard for self-hosted instances - After you deploy a self-hosted instance of Fabricate, the first time that you go to the instance URL, Fabricate provides a setup wizard that completes a compatibility check, installs the license key, and provides telemetry options.

Subdomain support for account domains - The account domains configuration now includes an option to allow traffic from subdomains. For example, when you add example.com, if you allow subdomain traffic, then api.example.com would also accept requests. The option is not available for pre-approved domains.

Freeform text model for mock APIs and workflows - You can now configure the model that a workflow or mock API uses for freeform text generation. To display the configuration setting, in the API or workflow heading, click the settings icon.

Account group assignment for API keys - You can now assign API keys to account groups.

You can now use the MCP server to get account groups, get usage by group, and get audit events by group.

When you stop a conversation, Fabricate now prompts you to determine how to handle any running workflows. You can detach the workflow from the conversation, which allows the workflow to continue to run in the background, or you can cancel the workflow.

Fixed an issue where testing a database connection created a server connection with the same name as the one used for the database connection.

Workflow parameters can now be flagged as secrets, meaning that the value is masked in the parameter field, API responses, and logs.

Fixed an issue where the Data Agent stop button was not properly re-enabled.

Fixed a couple of small display issues.
