 The `saved_track_data` table is used to preserve [track](tracks) data when tracks are deleted and restore the values if a track with the same mbid is later added. This lets us handle renaming files without losing the user's playback statistics. Note that this only works for tracks that have an MBID.
 
 ### Columns
+The `added` column was added to the table in schema version 2.
