New Built for Snow Leopard

Apple has seeded a new build for Snow Leopard, but unlike the previous one, this "developer preview" appears directly in the software update panel, instead of hte ADC website.
This new build tqgged, 10A402a, weights 1.32 GB, so you better have a good internet connection. Among the changes, menus is the dock are now on black bachground and Unibody models have now their dedicated icons.
