Is GLPK (the lib itself, not the Julia wrapper) still maintained and relevant ?
I can’t find any activity after 2020
Also wonder if it it still relevant or newer packages as HiGHS are the way to go nowadays…

GLPK is currently being maintained by [_mao@gnu.org_](mailto:mao@gnu.org), [_mao@mai2.rcnet.ru_](mailto:mao@mai2.rcnet.ru) .
Send him an email and ask.

Can’t speak for GLPK’s state of maintenance.
As far as solving LP/MILP problems, I recommend HiGHS as the default choice. It is much faster than GLPK and is actively maintained. It’s also released under dual MIT/GPL license, so it’s compatible with GPL code if that’s a constraint for you.

There is very little reason to use GLPK over HiGHS. One exception might be that GLPK supports callbacks such as lazy constraints.
But in almost every case, if the question is “should I use GLPK or HiGHS?” the answer is HiGHS.
