Changelog

Custom Python libraries in 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.

We're excited to announce Split Panes, the newest member of Frames. This layout pattern 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.

Split Pane is rolling out on Retool Cloud this week.

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.

We are excited to announce improvements to the loop blocks are now available in beta both Cloud and self-hosted deployments, versions 3.42 or later. If you'd like to participate in the beta, complete this form to request access.

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

Iteration-level timeout​

Loop block v2 allows timeouts of up to 30 seconds per iteration when executing the entire workflow.

Execution modes and delays​

Loop block v2 supports parallel, sequential, and batched execution modes with iteration delays.

Improved iteration-level error handling and metadata​

It is now possible to ignore iteration errors so that subsequent iterations can still run. In addition, metadata for each iteration is now exposed and accessible in subsequent blocks.
