-# Version 1.1
+# Version 1.2 [2025-10-14]
+# Changes:
+# - folder_created_date now uses the folder's (OS) creation time.
+# - folder_last_seen now uses the folder's last time it has been seen by the script.
+# - Added last_updated field track when the record was last modified.
+# ** This version is not backward compatible with previous versions, you will need to drop the existing table.

+# Version 1.1 [2025-10-07]
 # Changes:
 # - Updated table name to be configurable via DB_CONFIG
