+Subject: [PATCH 1/1] xcas.desktop: fix "Version" field.
+
+The "Version" field in a desktop file refers to the version of the
+specification, not the version of the software it launches:
+
+  https://specifications.freedesktop.org/desktop-entry-spec
+
+This issue has already been fixed upstream:
+
+  https://xcas.univ-grenoble-alpes.fr/forum/viewtopic.php?f=3&t=2716
+
+and will be part of the next release.
