Fedora 22 has built on the foundation with Fedora 21 and the work to create distinct editions of Fedora focused on the desktop, server and cloud. It's not radically different, but there are a fair amount of new features coupled with features we've already introduced but have improved for Fedora 22. The new Workstation release introduces more flexible firewall technology for developers.
Fedora (formerly Fedora Core) is a Linux distribution developed by the community-supported Fedora Project and owned by Red Hat. Fedora contains software distributed under a free and open-source license and aims to be on the leading edge of such technologies. Fedora has a reputation for focusing on innovation, integrating new technologies early on and working closely with upstream Linux communities. The default desktop in Fedora is the GNOME desktop environment and the default interface is the GNOME Shell. Other desktop environments, including KDE, Xfce, LXDE, MATE and Cinnamon, are available. Fedora Project also distributes custom variations of Fedora called Fedora spins. These are built with specific sets of software packages, offering alternative desktop environments or targeting specific interests such as gaming, security, design, scientific computing and robotics.
