-   **[Historical log back-fill](https://www.servicenow.com/docs/access?context=les-export-existing-logs-on-demand&family=brazil&ft:locale=en-US)**

You can now replay historical log data to your Kafka destination, in addition to live logs. A new setup screen lets you select the log table, date range, target topic, batch size, and throttling. Backfill settings are locked once a run begins to prevent accidental changes mid-run, and a live run status is displayed while the backfill is in progress.

-   **Broader log coverage**

LES now supports the following additional log source tables:

    -   sys\_flow\_log: Captures execution details and status of flow engine processes, for both live and historical export
    -   sys\_user\_login\_history: Captures user login attempts and authentication events
    -   Delete and relationship audit records \(sys\_audit\_delete and sys\_audit\_relation\) - so your compliance trail now includes record deletions and reference-field changes, not just regular field changes
