Changelog

Retool has deprecated version 1.0 of the Databricks connector. If your organization has any Databricks resources that still use this connector version, update the resource configuration to use the version 2.0 connector.

Self-hosted customers must also enable the Java DBConnector to use version 2.0 of Databricks connector.

Change the connector version from the Databricks resource's configuration settings. Any existing queries that previously worked with version 1.0 will continue to work with version 2.0.

The option to use version 1.0 of the Databricks connector will be removed in Q2 2025 from Retool Cloud and subsequent releases of self-hosted Retool.

Retool has deprecated version 1.0 of the MySQL connector. If your organization has any MySQL resources that still use this connector version, update their configuration to use the version 2.0 connector.

The option to use version 1.0 of the MySQL connector will be removed in Q2 2025 from Retool Cloud and subsequent releases of self-hosted Retool.

Due to potential security concerns, Retool is removing certain functionality that enables external app users to download images. No security breach or active vulnerability has occurred, and you do not need to take any security-specific actions.

External and embedded, publicly available apps will no longer support:

• Download Image columns in the Legacy Table component. Use an alternative method, such as a Link or Button column type, for image URL links. Retool strongly recommends you migrate to the current Table component instead.
• Export PDFs with images hosted on separate domains. All other components will be included in the PDF export. Retool recommends moving your publicly-hosted images to be hosted on the same domain as your Retool instance. For example, you could use images that are natively uploaded to the Image component, stored in Retool Storage, stored in Retool Database, Base64-encoded, or stored in an Amazon S3 bucket.

A new and improved version of the Checkbox Tree component is now available on Retool Cloud and for self-hosted organizations.

The new Checkbox Tree features:

• The ability to use manual or mapped option lists.
• Validation rules.
• Captions, tooltips, and other customization options.
• Support for infinite nesting.

Apps that contain modules are now much more performant and can load up to 1.5–2x faster than before. For self-hosted organizations, these improvements also reduce the resources needed by apps and modules, such as CPU load.

As a result of new features an improvements in self-hosted Retool 3.114, base memory usage for this and future releases is approximately 20% higher. If you experience performance issues after upgrading, consider increasing the allocated memory for your deployment.

You can now copy a query from one multipage app and paste it into another. Right-click on a query and select Copy then navigate or switch to a tab with another multipage app. You can paste the copied query as either a globally scoped or page-scoped query by right-clicking in the Code panel.

Query triggers, a new method for triggering workflows, are now available. Query triggers poll for messages from Amazon SQS and Kafka resources and execute a workflow's run for each message. These triggers are configurable to poll for messages on an interval or on a cron schedule.

Retool Storage is now available to self-hosted organizations as a file management interface for an S3 or Google Cloud Storage bucket. Because you control your own file storage bucket on self-hosted deployments, there are no data limits or overages for Retool Storage on self-hosted deployments.

You can set up integrations with Datadog and Sentry. With these integrations, app errors are reported with a callstack and descriptive tags when you view and interact with an app in preview or public (end-user) mode.

To connect third-party observability providers, you can report app errors using Retool Events and build a workflow that triggers whenever an app error occurs and automatically notifies your observability provider.
