I read the above changeloglet and read the above-linked page and it's still 87% unclear to me what this feature does. Something to do with stack randomisation, apparently. I suppose I could go do further hunting, but from the quality-of-changelog POV I don't think I should need to do so.
IOW: better changelog, please.
It's unclear to me that the random-number issue got sorted out?
