Fedora 40 firms up for release

> I won't miss delta RPMs. When present, they typically save well less than half a percent, and the extra complexity isn't worth the tiny savings.

While I agree that delta RPMs are likely not worth the effort for many today, I have to note that when it originally introduced in Fedora the percentage of download savings was regularly well over 50% and sometimes over 90% as seen for instance in the test results from 2009.

This was a frequent source of delight for users at that time and I am glad Jonathan Dieter, a community volunteer stepped up to make this happen along with others in Fedora. In recent releases however, it appears that Fedora infrastructure stopped producing the delta RPM packages consistently resulting in the advantages largely being lost. Hopefully broadband internet access has caught up elsewhere in the world that this isn't a barrier to getting updates.
