@leniwcowaty Knowingly distributing an old release of an app to a large, tech-illiterate audience, with hundreds of known bugs, pretending it’s the latest and greatest, and the support link pointing to the upstream issue tracker, is not “Long Term Support”. I’d say it’s the opposite, because this kind of abuse is actually damaging to the long-term survival of the upstream project.
If I were a GNOME Calendar developer, I’d be furious.
