Whether you’re using Lightning components, Visualforce, Apex, or Salesforce APIs with your favorite programming language, these enhancements help you develop amazing applications, integrations, and packages for resale to other organizations. Summer 24 Salesforce Development Release Notes.

  • Lightning Components
    Salesforce is modifying internal implementations of components and styles to prepare for SLDS architecture updates. LWC API version 61.0 provides ElementInternals Web API support and several bug fixes. Support for third-party web components is still in beta, and open mode now gives you access to the shadowRoot object. You can also navigate to a URL-addressable component and use the Utility Bar API in LWC.
  • Visualforce
    Check whether you’re affected when all unmanaged Visualforce pages are served on the force.com domain.
  • Apex
    Use new Apex cursors to break up the processing of a SOQL query result into pieces that can be processed within the bounds of a single transaction. Formula evaluation in Apex is now in beta. Use SOQL in Apex and mock SOQL tests for Data Cloud objects. Understand security considerations when using Apex with Data Cloud objects. Apex now supports SOQL relationship queries that traverse up to five levels of parent-child records. Track Apex scheduled job limits, edit jobs, and view enhanced job details on the All Scheduled Jobs page in Setup. Instance methods in a subclass don’t override private methods with the same signature. Monitor limits and cumulative run time for setup methods using ApexTestResult. See enhanced error messages on deleting a class, improved logging when FOR UPDATE locks are released, and information on org, user, and My Domain names in Apex exception emails.
