shellcheck updates to 64?

[jgart]

Hi, is this a bug? I ran `guix refresh -u` on shellcheck and it updated
shellcheck to version 64 but the latest stable release which was released
2 days ago is 0.9.0:

--
 (define-public shellcheck
   (package
     (name "shellcheck")
-    (version "0.8.0")
+    (version "64")
     (source
      (origin
        (method url-fetch)
        (uri (string-append
-             "https://hackage.haskell.org/package/ShellCheck/ShellCheck-";
+             
"https://github.com/koalaman/shellcheck/releases/download/stable/ShellCheck-";
              version ".tar.gz"))
        (sha256
-        (base32 "05jlapp4m997w36h2wszdxz9gvczdczaylypsbn14jqpb650w232"))
+        (base32 "08kn81xwkwsqjczn0w2kbf724p3q3acavmdnlbpb9i7g5n8fq6p3"))
        (file-name (string-append name "-" version ".tar.gz"))))
     (build-system haskell-build-system)
     (arguments
