If you guys are the ones in control of making the linux packages, please try to update the packages sooner after you release a new version. Specifically the Arch User Repo. Thank you!
The current maintainer of the AUR package is Arch user toastercup, so you need to poke him or ask someone from the Arch community to take over from toastercup
Use the SNAP as suggested on their website. AUR is as you said a *USER* (personal, not controlled by Hiri) repository.
You won't be notified about changes to this idea.
