Admins on the Enterprise plan can now complete each step in the Get started section of the Overview page using guided step-by-step wizards instead of navigating through separate Settings pages to complete configuration.

Overview page
You can now directly configure from the Overview page:
The Permissions setup step is only available to organizations with object roles enabled. If object roles are not enabled for your organization, this step will be hidden. Refer to Object roles for more information.
The Get started section is aimed at providing a better onboarding experience for admins of new organizations, and will help identify what configurations still need to be set up for admins or existing organizations. For example, setting up spaces walks you through choosing custom spaces or a Dev/Staging/Prod environment split, naming and configuring each space, and optionally copying over your existing SSO settings, before creating every space at once.
The Overview page also includes an Action center that contains important notifications and pending join requests, suggested users, and seat upgrade requests, so admins can act on what needs attention, as well an at-a-glance overview of your organization stats, such as total users, apps, workflows, and AI credit usage.
Self-hosted Retool instances can now connect to Gmail as a resource to read, send, and manage email using the Gmail API.
Self-hosted instances authenticate using your own Google Cloud OAuth client, so this integration is available now without waiting on Google's app-verification process for Retool's shared OAuth client.
Retool is deprecating versions 1.0 and 2.0 of the Microsoft SQL integration. Organizations with Microsoft SQL resources still using these versions must update their resource configuration to use version 3.0.
This deprecation will first take effect on cloud instances on August 24, 2026. It will then take effect in the next edge and stable releases that follow.
Version 3.0 has been available since February 2, 2026 for cloud instances and the 3.334 stable release. If you haven't intentionally created a resource on an older integration version, your resource is likely already on version 3.0 and requires no changes.
To upgrade an existing resource, open its settings from the Resources page, change Connector version to Version 3.0, and save your changes.
Versions 1.0 and 2.0 will be removed entirely from cloud instances in Q4 2026, followed by the subsequent edge and stable releases. After that, apps, workflows, and queries that depend on Microsoft SQL resources still using version 1.0 or 2.0 will stop working.
