Since modversions are ordered by number the modversions are all out of order. For example, in a list ordered from oldest to newest modversions, 4.2.19 comes before 4.2.2 (because 1 is smaller than 2, but 19 isn't smaller than 2). It should be the other way around, that's why I think modversions should be ordered by date and not by number.

Look, 1.2.12 is the latest version, though it's in the middle of the list. This makes it easy to make a dumb mistake when picking the correct modversion.
