The current version of the freedesktop specification is 1.5 but when using this value in a .desktop file a QA warning is shown saying
* QA Notice: This package installs one or more .desktop files that do not
* pass validation.
* /usr/share/applications/com.bitwig.BitwigStudio.desktop: error: value "1.5" for key "Version" in group "Desktop Entry" is not a known version
See https://specifications.freedesktop.org/desktop-entry-spec/latest/ar01s06.html for more info.
This is not handled by eclasses, portage calls desktop-file-validate from desktop-file-utils.
$ desktop-file-validate test.desktop
test.desktop: error: value "1.5" for key "Version" in group "Desktop Entry" is not a known version
Believe you should report this to desktop-file-utils upstream instead.
@Ionen Thanks! I wasn't aware of that.
I've created an upstream bugreport https://gitlab.freedesktop.org/xdg/desktop-file-utils/-/issues/59
