According to http://mirror.centos.org/centos/7/os/x86_64/Packages/, a git 1.8.3.1 is served. Which again is from 2013 according to the tag (Release v1.8.3.1 · git/git · GitHub).
So yes, that system needs an update…
This means nothing to me on any distribution, especially not on RHEL or CentOS. Especially after “latest” in EPEL seems to be OTP 16B3. Elixir 1.0 needs at least OTP 17. A current elxir needs at least OTP 19.
