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.

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.
