I have done a new diffoscope run with a new diffoscope;

And here are the images themselves, being uploaded as I write this;

So the 1111 dir is not yet populated, but should be complete with new
ISO later today. The ISOs are new from Monday.

Would love to hear your analysis. My quick analysis is that I'm still
unable to get the full report even with --max-report-size=0, perhaps I
need to look more closely at the diffoscope args. Also, it looks like
the differences between ISOs are relatively minor and this run the
diffs are smaller, but I don't know if it is fully 'reproducible.'
