We should upgrade.

I earlier tried building 0.2.5 but failed, see def. below.

(define-public artanis
(package
    (name "artanis")
    ;; The 0.2.5 tarball does not build. See upstream bugreport at
    ;; https://lists.gnu.org/archive/html/bug-artanis/2018-11/msg00000.html
    (version "0.2.5.af624e50")
    (source (origin
              (method git-fetch)
              (uri (git-reference
                    (url "https://git.savannah.gnu.org/git/artanis.git")
                    (commit "af624e508e9997bd2e20c8c7063d986694f11209")))
              (file-name (string-append name "-" version "-checkout"))
              (sha256
               (base32
                "0y1rx09jljdx6g6nq6y635f8svm8kazib7n4bgivi3yiy2c5v7ck"))
