+*Details* +
+The mechanism of exporting CSV data from a saved search panel in a dashboard has been changed to generate a CSV report, rather than allowing the CSV data to be downloaded
+without creating a report. To preserve the original behavior, it is necessary to update `kibana.yml` with the setting of `xpack.reporting.csv.enablePanelActionDownload:
+true`. The scope of this breaking change is limited to downloading CSV files from saved search panels only; downloading CSV files from other types of dashboard panels is
+unchanged. For more information, refer to {kibana-pull}178159[#178159].
