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?
