smart-status/CHANGELOG

@@ -19,3 +19,5 @@ Fixed the collapsible section showing raw SMART status output.
 Use disk IDs for SMART monitoring instead of device names, which may change.
 ---- Changes since 1.520 ----
 Fix support for 3ware hardware RAID arrays with non-contiguous disks.
+---- Changes since 1.710 ----
+Added a new status monitor type for alerting on the SSD wear level.
