[Mathieu Othacehe]

Hello Formbi,

When updating a package, the commit message has to follow a few
conventions detailed in the manual here:
https://guix.gnu.org/manual/en/html_node/Submitting-Patches.html.

> +(define-public libuv-1.38
> +  (package
> +    (inherit libuv)
> +    (version "1.38.1")
> +    (source (origin
> +              (method url-fetch)
> +              (uri (string-append "https://dist.libuv.org/dist/v"; version
> +                                  "/libuv-v" version ".tar.gz"))
> +              (sha256
> +               (base32
> +                "0iy6yp9nrxpj643w7la3kl3j59ni59b0l4v6n23a63s8kqkpvkhf"))))))

Regarding this very update, why do we need this specific version?

Thanks,

Mathieu
