Why are these updates rolling the version number backward?  Did the
later versions cause regressions?

Ah, light dawns.  I've been dealing with these version numbers for
years now, for 8388, 8686 and 8787, and I didn't know that.  Is this
documented anywhere else?  Have the 2nd and 3rd numbers any meaning or
are they random?

They're not random. They represent firmware branch and features built in.

Thanks,

So what do you they mean and why are they in the version number?

I don't think it is.

One of the nice things about standards is that there are so many of them.

This is a uniquely confusing way of generating version numbers.  If
only the current 4th part (what you call firmware revision) follows
the usual version ordering, then I think that should be used as the
(public) version number.
