Eidos Changelog works fine with 1-599, and errors cleanly (as expected) with any negative number as well as any number 600 or higher. But it crashes to desktop when given 0.

EDIT: It appears as though Eidos Changelog floors whatever number it is given before finding the appropriate position in the changelog. An input of 0.9 or something similar also crashes the game to desktop.
