The short answer

Salesforce Summer ‘26 preview orgs open on April 16, introducing key developer updates across Flow Builder and the platform user interface. Core additions include configurable batch sizes for Schedule-Triggered Flows, native lookup links in Data Tables, collapsible fault paths, and streamlined setup tools.

Key takeaways Register for a Summer ‘26 preview org starting April 16 to test existing automations and new developer features before production release. Set custom maximum batch sizes on Schedule-Triggered Flows to manage transaction limits and prevent governor limit errors during bulk processing [1.2.5]. Enable native record names and redirect links on Data Table lookup fields to remove the need for custom URL workarounds. Collapse Fault Paths on the Flow Canvas to streamline visual management of complex error-handling subflows.

Salesforce Summer ‘26 Preview: What Developers Need to Know

The Salesforce Summer ‘26 release cycle is officially underway. Preview org registrations open on April 16, allowing developers and architects to test new functionality before the general production rollout. This release brings substantial improvements to Flow Builder and platform UI.

Core Flow Builder Updates

1. Data Table Lookup Enhancements

Long-awaited improvements for the Data Table component simplify how lookup fields are handled. Developers can now enable a checkbox to display the record name and automatically configure a redirect link, eliminating the need for custom URL-building hacks.

2. Radio Button Group Component

Replacing standard, bulky radio buttons, the new Radio Button Group component provides a modern, space-efficient UI for Screen Flows, improving both aesthetics and usability.

3. Collapsible Fault Paths

Building on the modularity introduced in Spring ‘26, you can now collapse Fault Paths in the Flow Canvas. This is a major quality-of-life improvement for complex flows that utilize shared error-handling subflows.

4. Schedule-Triggered Flow Batch Sizes

Developers can now explicitly set maximum batch sizes for Schedule-Triggered Flows. This provides granular control over transaction limits, helping prevent governor limit exceptions during high-volume record processing.

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 provides a centralized, modern interface to audit field-level security, replacing some of the legacy 'View Field Accessibility' workflows.
  • Error/Warning Visuals: The UI for flow errors and warnings has been overhauled, organizing feedback into cards for better readability during the development process.
  • AI Content Summarizer: A new Lightning component, available in the App Builder, designed to provide AI-driven content summaries on Lightning record pages.

Platform Notable Mentions

  • Global Flow Resources (Beta): While still in early implementation, this feature suggests a new architectural approach for managing variables across multiple flows. We are monitoring this closely 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.

Key Takeaways

  • Register for Pre-release: Preview orgs are essential for validating existing automation against new platform behaviors.
  • Optimize Automation: Utilize the new batch size controls in Scheduled Flows to improve stability and performance.
  • Modernize UI: Take advantage of the Radio Button Group and updated error cards to improve the end-user experience in your custom flows.
  • Stay Informed: Keep an eye on the official release notes arriving April 22 for full technical specifications on these features.

Frequently asked questions

How do you display record names for lookup fields in a Flow Data Table?

In the Data Table component settings, enable the checkbox to display the related record name and automatically generate a redirect link [1.3.3]. This eliminates the need to construct custom URL formulas.

How do you control batch sizes in Schedule-Triggered Flows?

Developers can explicitly define the maximum batch size directly within the Schedule-Triggered Flow configuration. This provides granular control over transaction limits and helps avoid governor limit exceptions when processing large record sets.

How do you allow users to edit shared list views in Salesforce?

Enable the shared list view editing toggle in the User Interface setup menu. This allows users who have the 'Create and Customize List Views' permission to edit list views that have been shared with them.
