Changelog

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.

These features are no longer available on Retool Cloud and Self-hosted Retool 3.114-edge or later. These features will be removed in the next stable release of Self-hosted Retool.

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.

These performance improvements are available on Retool Cloud and the current edge release of Self-hosted Retool. The improvements will also be part of the next stable release of Self-hosted Retool.

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 workflows run for each message. These triggers are configurable to poll for messages on an interval or on a cron schedule.

Query triggers are currently rolling out on Retool Cloud. This feature will be available in public beta on Self-hosted Retool 3.117 Edge and the next stable release.
