Track Source Changes in Sandboxes Automatically (Beta)

When source tracking is enabled in a Developer or Developer Pro sandbox, the sandbox automatically tracks changes between the sandbox and the local workspace. When you pull sandbox changes into your project or push project changes to the sandbox, only the changed source is synched back.
Where:
This change applies to Lightning Experience in Enterprise, Performance, and Unlimited editions. Note that source tracking is available for Developer and Developer Pro sandboxes only. Partial and Full sandboxes are not supported.
