Think Secret offers a gallery of screenshots from build 9A466 of Leopard as well as some details on applications included;

Safari 3, which has been part of Leopard since day one, sees a further rev in Leopard to version 3.0 (5522.8.3). For those keeping score at home, the beta of Safari 3 for Tiger is at version 3.0 (522.11).

Photo Booth 2, which was badly broken in Leopard 9A410, is working almost flawlessly again, and most other bundled application and utilities have newer build numbers in 9A466, although without any apparent substantial changes. The lone exception is Preview, which is now at version 3.5 for the first time. Tiger’s Preview is at version 3.0.9, and previous Leopard builds contained Preview 3.1.

While the improvements in Preview 3.5 seem the same as Preview 3.1, the About box curiously mentions that “Map imagery owned by NASA”, although at first glance there doesn’t appear to be any way to access any sort of map imagery in Preview 3.5, perhaps foreshadowing a feature that has yet to arrive.

Leopard also continues to grow considerably in size: build 9A410 was roughly 5.4GB in size, while 9A466 tips the scales at almost 6.1GB.
