Worlds very different from Earth no longer restart their settle by mistake and drop into a sudden cold snap ("Zealandification"). They now settle at the right temperature, often sooner.
Titan now shows its true dull orange, with no blue tint over its haze and no ground showing through it.
The shadow of a giant's rings now falls only on its sunlit side, and no longer runs as a dark band across the night side.
Scanlines now run evenly across the System View, instead of stopping along the edge of the map behind it.
