Improve Performance With Record-Triggered Flows That Run Only for Specific Changes
We added entry criteria to record-triggered flows that update records, giving you more
control over your automation. You can configure the flow to run every time a record that meets
specified criteria is updated, or only when a record is changed to meet the criteria. Depending on
the flow, this optimization can significantly reduce the impact that record-triggered flows have
on your Salesforce org’s performance.
Where: This change applies to Lightning Experience and Salesforce Classic in Essentials, Professional, Enterprise, Performance, Unlimited, and Developer editions.
How: Create a record-triggered flow. Click Edit in the Start element. Select A record is updated or A record is created or updated.

Choose the object whose records trigger the flow to run. Define the condition requirements for the triggering record. Choose when to launch flows for updated records: every time a record that meets the requirements is updated, or only when a record is updated to meet the requirements. The latter option allows you to launch flows only when the triggering record changes from not meeting the specified requirements to meeting them.
