Arches, please test and stabilize this latest version of glpk. The ebuild itself has been in the tree for a long time, but this package may have some finicky reverse dependencies that I'm unaware of. The changelog does suggest that the upgrade (despite being a new major version) should be relatively safe: https://lists.gnu.org/archive/html/info-gnu/2020-12/msg00007.html
