They introduced a change that allows them to introduce smaller iterative changes as and when and not HAVE to bundle those into the big ones. Doesn't mean that large updates like this are in anyway faster to download.
But that's not what I was talking about, at all.
If anything, the opposite: I never had problems downloading a large number of gigabytes because my line (1 Gbit/s optic fiber) allows me to do it quickly, but this update spent A LOT of time processing the files.
