New and changed features

Apple advertised that Mac OS X v10.2 "Jaguar" had new features, such as:
Address Book — A system-wide repository for contact information in the updated Address Book.
Rendezvous — Rendezvous, later named Bonjour, is Apple's implementation of an IETF open protocol
CUPS the modular printing system for Unix-like operating systems.
Finder — A revamped Finder with searching built directly into every window.
Mail — A mail client with an adaptive spam mail filter.
Network support for Microsoft Windows networks — Increased support for networks in Jaguar. Apple added much more support for Microsoft Windows networks, and Microsoft Windows sharing protocols. Most of the changes were added behind the scenes, which included new Samba tools, and new printing protocols.
Quartz Extreme — Quartz Extreme was added for compositing graphics directly on the video card, without the use of software to composite windows. The technology allotted the task of drawing the 3D surface of windows to the generally idle graphics processing unit, rather than to the central processing unit. Overall, the technology benefited the areas of user interface responsiveness and general speed enhancements throughout.
Sherlock 3 — Web services.
Universal Access — Dozens of new features here.
Increased speed across the entire system.
Journaled file system (first introduced in 10.2.3 Server, later made available to 10.2.x clients).
