I have never seen such drastic net change in a routine system update. Seems like either something is wrong and I shouldn't update or that something used to be very wrong and some smart dev just now fixed it.

Is there an easy way to see per-package size change, to know which package(s) contribute to the net change? I am only aware of the cumbersome way of comparing 'pacman -Qi package' output with that of 'pacman -Si package'.

It's probably just the new change in the linux-firmware package. Saves a lot of disk space.

Yes, there is.  Uncomment VerbosePkgLists option in pacman.conf.  Or add it to the [options] section, it it's not already present.

$ dt && sudo pacman -Syu

Make sure that the terminal window is wide enough to display all columns.  Otherwise pkgs will be displayed in tradiitonal, not-tabled format and you'll get the warning:

warning: insufficient columns available for table display

So it is. That makes sense. Wish there was a better solution for shipping the WHENCE file, though, other than making it another package. (I'm not saying there is.)
