Changelog

Retool released a Version 3.0 of the Microsoft SQL Server integration that includes various fixes and improvements. New Microsoft SQL resources will use this version by default. Existing resources can be updated using the Connector version setting.

Beginning in the 2026 Q3 stable release, Version 1.0 and Version 2.0 of the integration will be deprecated. Retool strongly recommends that you update your resource configuration before Q3 in order to prevent any interruptions and to resolve any unforeseen issues. If necessary, Retool may automatically migrate resources to Version 3.0 in order to ensure any issues are identified and resolved prior to the removal of the old versions.

There is a known breaking change introduced in Version 2.0 that will also apply when upgrading from Version 1.0 to Version 3.0:

Beginning in Version 2.0, array inputs must be passed as a string when used in string_split in order to pass the Microsoft SQL SDK validation. For example, select * from string_split({{[1,2,3]}}, ','); must change to select * from string_split({{[1,2,3].join(',')}}, ',');.

No breaking changes are expected between Version 2.0 and Version 3.0.

For Enterprise and Business plans, Retool now allows admins to control access to Assist and its Ask and Build modes. Organization admins can use roles and permissions to create roles and edit roles with one of the following permissions:

• Use Assist with Ask and Build mode
• Use Assist with Ask mode only
• No access to Assist

By default, all users have access to Assist and both Ask and Build mode through a preconfigured role. This role is called Assist Role or Editor, based on when your organization was created. Organization admins can edit these roles, or they can create new roles with more restrictive permissions.

This change is valuable for organizations that need to limit or prevent Assist usage to specific populations of users. For example, admins might wish to restrict Assist usage to user groups who do not have access to sensitive data or PII. Alternatively, admins could restrict access to all user groups except for a pilot group testing AI tools.

Multi-instance releases are now generally available to cloud instances and self-hosted instances on version 3.330 or later, with support for both apps and workflows.

Organizations using Source Control can manage releases of protected apps and workflows across multiple deployment instances. This feature enables you to publish different release versions across instances, making it easy to test newer versions on staging or development instances before promoting to production.

Beginning in the Q3 2026 stable release, self-hosted instances using the multiplayer feature must set the LICENSE_KEY environment variable on the multiplayer service container. While this environment variable is not yet required, Retool recommends setting it now to avoid any service interruptions.

You can now unpublish workflow releases from the Releases tab.

This feature is also available for workflows protected with Source Control. When unpublishing a release on a protected workflow, the latest saved version on the main branch will be live to users.

Assist now supports the ability to create and edit multipage apps. Previously, Assist could only work with one page at a time.

Assist can now:

• Plan and build a multipage app from scratch.
• Create, edit, and rename pages.
• Move queries and code between global and page scopes.
• Create globally-scoped frames and components, such as Navigation, to help users move between pages.
• Identify and correct page scope errors.

While Assist is generating, navigating between pages is disabled to prevent errors.

A number of security vulnerabilities in the React framework and related frameworks, like next.js, were recently disclosed. These vulnerabilities did not impact Retool.

• CVE-2025-55182
• CVE-2025-55183
• CVE-2025-55184

These vulnerabilities were related to React's server-side rendering systems which are not used by Retool. As such, there is no action for cloud- or self-hosted customers to take.

Retool's website was also not impacted. We confirmed with our vendor that these vulnerabilities were already mitigated before being publicly disclosed. After the patches were released they applied the patches the same day.

Retool now supports two modes for prompting with Assist: Ask and Build. Use Ask as a safe, read-only way to understand and debug your app without adding or changing components or logic, and Build when you’re ready for Assist to make edits.

• Ask mode: Assist replies with explanations, suggestions, or debugging help. When in Ask mode, Assist cannot modify your app.
• Build mode: Assist can create and edit components, queries, and logic in response to your prompt.

Both modes use the same understanding of your app, your data, Retool features, and documentation.

Assist defaults to using Build mode. You can switch between modes at any time.

Retool added support for DeepSeek-V3.2 in Baseten. DeepSeek-R1 is no longer supported, and DeepSeek-V3.2 will be used instead.

OpenAI's model GPT-5.2 is now available in Retool. It can be used with AI actions and with Retool Agents.
