Looking into the full 7.2 and the Upgrade-7.1.x-to-7.2 zip files I found some possible (little) issues.
These files are only at upgrade pack, not in the full pack. It is ok?

These files have same contents but different copyright notices. So you are getting those files from different places when creating zips.
True?

Hope you find this useful, even if they are not big issues!
But as you can see, there is nothing I can do except report the issues!
