While it’s becoming very popular among Linux users as it is more and more adopted by Linux OS vendors, Flatpak is still considered an “under development” technology, and so it’s not yet promoted on a mass scale as its rival Snap is by Ubuntu’s mother company Canonical. However, Flatpak as it is right now, it’s very usable, but it is yet to achieve the 1.0 version milestone, which usually marks a project as mature and ready for mass deployment. And it’s now more closer than ever as the development team announced today the availability of the first Flatpak 1.0 pre-release version.
