Salesforce Summer ‘26 Preview Orgs: Key Developer Updates

Salesforce Summer ‘26 preview: what developers need to know

The Salesforce Summer ‘26 release cycle is underway. Preview org registrations open on April 16, so developers and architects can test new functionality before the general production rollout. The changes land mostly in Flow Builder and the platform UI.

Core Flow Builder updates

1. Data Table lookup enhancements

Lookup fields in the Data Table component get easier to handle. Developers can now enable a checkbox to display the record name and automatically configure a redirect link, so the custom URL-building hacks can go.

2. Radio Button Group component

The new Radio Button Group component replaces the standard, bulky radio buttons with a compact control for Screen Flows.

3. Collapsible Fault Paths

Building on the modularity introduced in Spring ‘26, you can now collapse Fault Paths in the Flow Canvas. Complex flows that use shared error-handling subflows get the most out of this one.

4. Schedule-Triggered Flow batch sizes

Developers can now set maximum batch sizes for Schedule-Triggered Flows explicitly. That gives you control over transaction limits and helps prevent governor limit exceptions when a run has a lot of records to process.

User interface and setup improvements

• Shared List View Editing: a new toggle in the User Interface setup menu allows users with the 'Create and Customize List Views' permission to edit list views that have been shared with them.
• Object Manager Field Access: a new 'Field Access' tab in Object Manager gives you one place to audit field-level security, replacing some of the legacy 'View Field Accessibility' workflows.
• Error and warning visuals: the UI for flow errors and warnings has been overhauled, grouping feedback into cards that are easier to read while you build.
• AI Content Summarizer: a new Lightning component, available in the App Builder, that produces AI-driven content summaries on Lightning record pages.

Other platform notes

• Global Flow Resources (Beta): still in early implementation, this suggests a new architectural approach for managing variables across multiple flows. We are watching it as a potential flagship feature.
• Web Console (Beta): launching April 14, the new Web Console promises a more integrated way to execute code directly within the Salesforce environment.
