Take a Flow Path Only When Certain Record Changes are Made
Where: This change applies to Lightning Experience and Salesforce Classic in Essentials, Professional, Enterprise, Performance, Unlimited, and Developer editions.
Why: This option gives your flows a powerful filtering feature similar to the ISCHANGED function found in Workflow Rules and Process Builder and the oldMap/newMap variables found in Apex. Build more of your automation directly in Flow Builder without requiring Process Builder or Apex to check the prior version of the data.
How: On a record-triggered flow, configure the Start element to trigger when the record is updated, or when it’s created or updated.
