Yes, it is a new release. When upstream releases a new version, they
publish it at this URL. The old version that was available at that URL
before is then taken offline and can no longer be downloaded from their
website.

At the moment, the tarball with hash XXX at the download URL is silently
replaced by another tarball with hash YYY but identical name
(sparta.tar.gz) whenever they release a new version, which happens up to
several times a month. I tried to explain to the author that this is
problematic for the authentication of the tarball via SHA sums and for
reproducibility and I suggested to him to append the release date to the
tarball name and keep the old ones available. Unfortunately I have not
received a reply yet.

Thank you for your review! I am working with this software almost every
day on several computers managed by Guix so I would love to see this go
in.
