Apple Revised Mac OS X 10.4.7 (Intel) Install Package But Situation Unclear

We received the following note from Apple,

Mac OS X v10.4.7 was released on Tuesday of this week. The install
package that upgrades a Mac OS X v10.4.6 (Intel) system is being
revised. The revision is to provide several files related to OpenGL
performance that were missing.

Only the package that upgrades a Mac OS X v10.4.6 (Intel) system to
Mac OS X v10.4.7 (Intel) is being changed. All other Mac OS X
v10.4.7 install packages remain unchanged.

The change being made to the install package does not affect the
security fixes provided in the package.

The new package is named: MacOSXUpd10.4.7Intel.dmg
It's SHA-1 digest is: 10aa57dfccd63accb0939a894cea202a8910fb45

We believe that this means that if one updated an Intel-based Mac to 10.4.7 using the delta updater that one will need to apply a revised updater when issued. However, if one used Software Update or the stand-alone Combo edition of the updater, then perhaps one does not need to reinstall Mac OS X 10.4.7 (Intel) but that is not completely clear. We used Software Update on our Intel-based Macs and have not experienced any graphics issues.

According to MacFixIt, Apple has now posted a revised delta updater (MacOSXUpd10.4.7Intel.dmg) and MacFixIt provides a procedure to confirm it. Unfortunately, Apple has not posted an explanation nor updated the posting date for the update's listing on Support/Downloads or its specific Web page. It seems to us that the safest and easiest procedure is simply to apply the combo updater. [Bill Fox]
