You can now create a README from the workflow IDE to help clarify important information about your workflow for collaborators. For example, if a workflow requires certain permissions on a resource, or if it's only scheduled to run once a week.

This feature is also available for workflows protected with Source Control. To create a README, click the title of the workflow and add content to the Editor README field. READMEs are visible from the Edit workflow details dialog box, in workflows JSON exports, and in a markdown file from source control.

You can protect an agent with Source Control from the dropdown next to the agent name, or from the dropdown on the All agents page.

Source Control for agents operates similarly to how it does for apps, but with some key differences.

• Agents cannot be moved or renamed. Protected agents and the folders in which they're located cannot be renamed or moved. You must unprotect agents before making name or location changes. Protected agents must have a unique name.
• Agent triggers cannot be protected. You can edit the trigger of a protected agent without creating a commit.
• Evals and Datasets are incompatible. You cannot access evals and datasets from a protected agent.

You can now see the output of an agent run with the Result (sync) return type when using the Invoke Agent block in workflows.

• The Result (sync) type is the default setting. This returns the direct result of the agent's output.
• The Run state (async) type returns the agentRunId, agentId, and status only. It does not include the output of the agent.

Retool's Slack integration now supports the files.getUploadURLExternal and files.completeUploadExternal APIs for uploading files. Slack ended support for their files.upload API on March 11, 2025, and this endpoint is no longer available in the Retool Slack integration.

For most users, no action is required to access the new APIs. For self-hosted organizations that set the SERVE_LOCAL_SPECS environment variable, you must upgrade to version 3.168.0-edge, patch release 3.148.2, or patch release 3.114.17 to access this change.

The workaround described in the Action Required: Update Slack queries using files.upload changelog entry is no longer required.

Slack is ending support for their files.upload API on March 11, 2025. Refer to the Slack changelog for more information.

Retool is working to update our Slack integration as quickly as possible. In the meantime, if you need files.upload functionality, you can use a REST Query to utilize the new files.getUploadURLExternal and files.completeUploadExternal APIs.

This workaround is temporary, and Retool will restore access to file upload functionality within the Slack integration as soon as possible. Another changelog post will be made when the ability to upload files is restored. Other functionality in the Slack integration remains uninterrupted.

Split Pane is a new web app frame pattern that allows users to create a resizable and scrollable frame, with a custom width, alongside the main canvas. You can add a Split Pane frame from the Frames section, or drag it onto the canvas from the Component Tree.

You can now set private or public access for files uploaded to Retool Storage. Each file in your Retool organization has a public URL that you can enable by making the file public.

Files uploaded to Retool Storage are private by default, and you can switch between private or public access at any time. When uploading files with a Retool Storage resource query, you can enable Make file public on upload to automatically make them public.

We're continuing to make performance improvements after recently upgrading to React 18. Update batching groups state updates together, rather than perform each one separately, to optimize performance. This results in a more responsive experience in Retool and faster page load times.

Enterprise plan organizations on cloud instances or self-hosted instances running version 3.38 or later can connect and send all audit log events to Datadog.

The new Linting and Performance tools, available within Debug Tools in the App IDE, provide additional methods for debugging and optimizing apps.

Linting​

Identify queries, code, and components that may affect app performance.

Performance​

View statistics related to app performance along with an overall performance score. This is a useful tool for measuring how changes affect an app's performance and provides guidance on how to optimize it further.
