Changelog

Custom component libraries is the new approach to building custom React components for web apps. Previously, custom components were built directly within the App IDE. With custom component libraries, you can now build components locally in your development environment, then deploy to Retool. After deploying, you can drag and drop components into apps as you would any other component.

Custom components are contained within libraries, and each library has a unique name. Custom components deployed to Retool are automatically shown in the Component Library.

Custom Python libraries for Retool Workflows is now available as a public beta. You can add one of the built-in Python libraries or provide a custom list of libraries and versions.

Retool Mobile for iOS and Android now supports biometric security. Users are prompted to verify their identity using biometrics (e.g., fingerprint or facial scan) each time they open the app.

You can also enable a privacy screen that obscures the mobile app when it appears in the device's app switcher. This can prevent sensitive information being potentially made visible.

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 enable collaborators on Source Control branches. Source Control branches are private by default and only allow changes by the owner. On collaborative branches, multiple users can commit changes and submit pull requests to protected elements.

Webdriver tests are a great way to ensure that your Retool app is working as expected. They can be run on your local machine, against a staging instance, or in a CI/CD pipeline against your development branch to ensure that your app is working as expected.

A new and improved version of the Loop Block is now available in beta. If you'd like to participate, complete this form to request access.

The new Loop Block features:

• Iteration-level timeout of up to 30 seconds when executing the entire workflow.
• Parallel, sequential, and batched execution modes with iteration delays
• Improved iteration-level error handling to allow subsequent iterations to run.
• Iteration metadata that is accessible in subsequent blocks.

Once enabled, any new Loop blocks added to workflows will use Loop block v2. Existing Loop blocks will continue to function as before.

The new Add new row Toolbar action makes it possible to input values directly into the Table component. New rows are added to the table's changeset to save. Adding rows directly to a table provides an alternative method to using a separate Form component and input fields.

Retool is aware of CVE-2024-3094, a backdoor affecting versions 5.6.0 and 5.6.1 of xz-utils. Self-hosted Retool images are not affected, and no action is required. Retool Cloud infrastructure and services are not impacted.

If you have any questions or concerns, please reach out to security@retool.com.

Internationalization (i18n) is now in beta for organizations on the Enterprise plan. This allows you to localize Retool app content and data.

This beta is available on Retool Cloud and self-hosted deployments running Retool 3.38 or later. Contact your Retool account team to request early access.
