yes,in an earlier post; six packages from packages moved to AUR and probably some leftovers,
and it seems they changed the name of the the Skype one and removed “stable” from it which prevented it from updating(i assume).
Changelog for skypeforlinux-bin on AUR shows initial release date of 2016
+ # Wed Jul 13 14:51:23 UTC 2016
+ pkgbase = skypeforlinux-bin
+ pkgdesc = Skype for Linux WebRTC Alpha
+ source = https://go.skype.com/skypeforlinux-64-alpha.deb
My pacman log shows I had this package installed in 2017, but it was replaced in 2018
Last update for skypeforlinux-stable-bin 8.109.0.209-1 was released Dec 2023
