Everyone knows the UE4 downloads are pretty big. Given that, it might be worth trying to optimize the system that determines what needs downloading and when.
I was 95% through downloading 4.8.0 when I paused it and later shut down my computer. Next time I’m back on, 4.8.1 is up and it starts downloading again from scratch. I don’t know how big the 4.8.1 hotfix download is if you already have 4.8.0 installed, but clearly this kind of thing should be largely avoidable.
Not a big deal, but a bit annoying and something that could definitely be improved.
