Other builds that were pushed stable between the two TC compose times
will also change. There is no easy way we can list those out as it's not
really stored anywhere. the deltaISO is probably the best change record
we have. Of course, during a freeze, only blocker/NTH fixes will get
pushed stable in this way, and we have good records of those. I thought
the final pre-freeze stable push was included in TC8, but by the looks
of that delta, some of it at least might not have landed until TC9.

Other things that can change are the kickstarts used to compose the live
images, and comps. You just have to look at the git log to figure those
out.

It's not perfect, I know.
