Printing History

New editions are complete revisions of the manual. Update packages, which are issued between editions,
contain additional and replacement pages to be merged into the manual by the customer. The dates on the
title page change only when a new edition or a new update is published. No information is incorporated
into a reprinting unless it appears as a prior update; the edition does not change when an update is
incorporated.

A software code may be printed before the date; this indicates the version level of the software product at
the time the manual or update was issued. Many product updates and fixes do not require manual changes
and, conversely, manual corrections may be done without accompanying product changes. Therefore, do
not expect a one-to-one correspondence between product updates and manual updates.
