Die Roadmap in github (https://github.com/linuxmint/Roadmap) sieht aktuell wie folgt aus:

- Replace gnome-settings-daemon with cinnamon-settings-daemon
- Replace gnome-session wich our own session manager or a simple xsession script
- Review any remaining GNOME backend components and dependencies
- Factorize translations into cinnamon-translations
- Implement a non-accelerated fallback GTK panel and session
- Consider shipping our own version of gjs (as opposed to using the system one and in an effort to ease backports)
- Convert all system applets, desklets to use settings api
- Calendar events - similar to KDE's implementation [lockjs]
- Upgrade Menu applet with mintMenu features (highlight new apps, install/remove apps, search the Web) [clem]
- Use bumpmaps, make them optional, make compositing optional if possible

Klingt nach mehr Forks, aber wenig tatsächlicher Arbeit.

Die Datei scheint recht aktuell zu sein.
