Hi! Compressed updates and even delta updates - the fact you download only the new resources instead of all resources - isn't new. However, I never seen it applied at scale. Well, I should watch one day if Android does it but I don't know yet. Until Fedora. Fedora, since some releases, includes Delta RPMs, which basically software packages where you download only what's new in the package. All the already downloaded resources are not downloaded and so you can save something like 30% of download time, just with that. The thing is, because it is applied to the package system as whole, all software updates are downloaded that way. I don't know if other RPM-based Linux does it, but I find the idea great. Simple, but great. What do you think of it, honestly? Do you already think about improvement?
