RHEL 7 has Make 3.82. Its regular life cycle ends in 2024, and I assume it will have an extended support period after that.

TIL that after the 5 year "full support" period (which is what I had in my head), RHEL has a 5 year "maintenance support" period (and that CentOS matches that 10-year total) (and then the "extended lifecycle support" arbitrarily long after that for whoever wants to pay enough).

(Aside: 3.82 is a surprising version to be stuck with... most distros went straight from 3.81 to 4.0, because by the time the show-stopper bugs in 3.82 were all patched, 4.0 was happening.)
