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.

Retool will deprecate the use of YAML for protected apps, queries, and resources in Source Control. Support will be removed in the Q2 2025 stable release of Self-hosted Retool.

Self-hosted organizations still using YAML serialization of these elements in Source Control must migrate to Toolscript prior to upgrading.
