 # DONE
+# Changed to add drives' firmware version to the db files (to support data deduplication).
+#    See https://github.com/007revad/Synology_enable_Deduplication
+#
+# Changed to be able to edit existing drive entries in the db files to add the firmware version.
+#
+# Now supports editing db files that don't currently have any drives listed.
+#
+# Fixed bug where the --noupdate option was coded as --nodbupdate. Now either will work.
+#
 # Fixed bug in re-enable drive db updates
 #
 # Fixed "download new version" failing if script was run via symlink or ./<scriptname>
