Enhancements Otherwise, the update delivers a large number of enhancements in the following categories: digital-hub and peripheral-device enhancements; networking and modem enhancements; Address Book and Mail enhancements; application enhancements; and "other" enhancements.

Specific highlights include: addressing an issue in which printing more than one copy of a file from Adobe Photoshop 7.0 to a postscript printer failed; a series of improvements to the reliability of built-in modems; Address Book can now better import groups from previous versions of Address Book; and issues when transferring v-cards from Address Book to a cellular phone via Bluetooth have been resolved. The update also brings Apache up to version 1.3.27.

This 24.4MB update also brings the operating system's security features up-to-date.
