When changes are made to ModItem or ModBiblio (or the routines that are called by those), it is sometimes necessary to run ModItem/ModBiblio on every single record in the catalog when upgrading. The misc/maintenance/touch_all_items.pl and misc/maintenance/touch_all_biblios.pl scripts do this for items and biblios, respectively.
