MarsSeed [1] filed a request to merge arduino-mk [2] into arduino-mk- git [3]: The last stable tagged release is from 2017, but the git master branch is 4 years and 140 commits newer. The purpose of upstream repo is to provide example Makefiles and demo code for Arduino programming. I think the use case warrants acquiring the latest, most refined code from the git repo. Also, AUR/arduino-mk has long been abandoned, whereas the '-git' package has an active maintainer who recently pushed a PKGBUILD fix for the latter.
