     <p>While Flatpak is independent of the GNOME project, GNOME is actively promoting its use as a part of 
its developer experience. Since the 3.22 release, Flatpak has made significant progress. There have been a 
total of eight Flatpak releases since then, which have introduced a host of major new features and 
improvements.</p>
