+=head1 UPGRADING FROM 3.3.2 AND EARLIER
+
+Viewing custom fields now requires the "SeeCustomField" right either globally
+or on a per-queue basis. Global CFs are no longer visible to everyone and
+SeeQueue is no longer sufficient to view queue-level CFs. You must grant the
+"SeeCustomField" right manually after upgrade.
