actually, none of the new builds of jaguar have any new features (any newer than previous builds, that is). apple stopped adding features to jaguar quite a while ago, and is in the final stages of debugging (presumably), so no new jaguar builds have new features, just fewer bugs.
if you want to know what new features will be new in all jaguar builds (both old and new) when compared to 10.1, check out this website. it has screenshots, and a list of new features.
