pacman -Qi ranger lists atool as an optional dep “for previews of archives”.
I installed atool on 2022-01-31 using pacman -S:
$ grep atool /var/log/pacman.log
[2022-01-31T19:25:19+0530] [PACMAN] Running 'pacman -S atool'
[2022-01-31T19:25:25+0530] [ALPM] installed atool (0.39.0-7)
$
but recently I installed EOS on another machine and found that atool isn’t in the regular repos any more but in the AUR.
Is there a Arch page that documents removal of packages?
Hm. That’s definitely a packaging bug.
Reported, https://bugs.archlinux.org/task/74141
No idea about any database of removed packages, but the AUR page for atool does tell that its a recent addition.

Also, the wiki seems to be recently updated to change link of atool from repo to AUR.
https://wiki.archlinux.org/index.php?title=Ranger&type=revision&diff=716585&oldid=715081
It has been dropped from the standard arch repos to the AUR.
The bug you linked to has the reason 
.
I’m guessing it’s better to learn to do without it.
I wonder why… 
Your bug report has a comment pointing to this bug and quoting from the latter bug:
Description:
atool uses hardcoded permission when creating new directories. This introduces problems for use-cases of multiple users on a system trying to handle files on shared volumes.
Additional info:
- package version(s)
0.39.0-7- link to upstream bug report, if any
Upstream is basically dead so here’s a fork with the issue fixed. https://github.com/z3ntu/atool/issues/1
Does that suffice?
It was supposed to be a tongue-in-cheek comment because the bug report just includes information that was already in this thread.
