Deltarch lists every pending update from the repos and the AUR, separates real changes from packaging-only rebuilds, and shows what each one brings before you apply anything.

Many Arch updates are pkgrel rebuilds with nothing new upstream. Deltarch spots them locally with no network call, so the list in front of you holds only updates that actually changed something.
Pending updates from checkupdates and the AUR in one list, with live counts.
Packaging-only pkgrel rebuilds are detected locally and grouped out of the way.
Old and new version, download size, installed size change and dependencies affected.
Everything pacman has changed, read from its log, with most-updated packages and weekly stats.
Shows what pacman.conf holds back with IgnorePkg, so held packages are never a surprise.
Looking never touches the system. Deltarch never runs pacman -Syu on its own.
