The Fedora Project is delighted to announce the release of Fedora 18 ("Spherical Cow"). Fedora is a leading-edge, free and open source operating system that continues to deliver innovative features to many users, with a new release about every six months, and Spherical Cow, is of course, Fedora's best release yet.

What's New in Fedora 18?

The Fedora Project takes great pride in being able to show off features for all types of use cases, including traditional desktop users, systems administration, development, the cloud, and many more. But a few new features are guaranteed to be seen by nearly anyone installing Fedora and are improvements that deserve to be called out on their own.

The user interface for Fedora's installation software, Anaconda, has been completely re-written from the ground up. Making its debut in Fedora 18, the new UI introduces major improvements to the installation experience. It uses a hub-and-spoke model that makes installation easier for new users, offering them concise explanations about their choices. Advanced users and system administrators are of course still able to take advantage of more complex options. The general look and feel of the installation experience has been vastly upgraded, providing modern, clean, and comprehensible visuals during the process. While the new installer should work well for most users in most configurations, there are inevitably a few problems in the first release of such a major revision: see the known design limitations of the new installer in Fedora 18, and known significant bugs for more information.

The upgrade process for Fedora now uses a new tool called FedUp (Fedora Upgrader). FedUp replaces pre-upgrade as well as the DVD methods for upgrading that have been used in previous Fedora releases. Systemd provides most of the upgrade functionality, doing the work in a unique boot environment.

Of course, it wouldn't be a release announcement without a list of all the other fantastic features you'll see in Fedora 18:

For desktop users

If you want choice in desktops, Fedora is the distro for you. Fedora 18 includes:

  • GNOME 3.6 The newest version of the GNOME desktop provides an enhanced Messaging Tray, support for Microsoft Exchange and Skydrive, and many more new features. For more information, visit the GNOME release notes.
  • KDE Plasma Workspaces 4.9 KDE Plasma Workspaces has been updated with many new features and improved stability and performance, including updates to the Dolphin File Manager, Konsole, and KWin Window manager.
  • MATE Desktop The MATE desktop provides users with a classic GNOME 2.x style user interface. This desktop is perfect for users who have been running GNOME Classic or other window managers like XFCE as an alternative to GNOME 3.
  • Cinnamon Fedora users now have the option of using Cinnamon, an advanced desktop environment based on GNOME 3. Cinnamon takes advantage of advanced features provided by the GNOME backend while providing users with a more traditional desktop experience.
  • Xfce 4.10 The lightweight and easy-to-use Xfce desktop has been updated to the 4.10 version with many bug fixes and enhancements, including a new MIME type editor, a reworked xfce4-run dialog, improved mouse settings, tabs in the Thunar file manager, and options to tile windows in xfwm4. Through all of these and more, Xfce continues to improve without getting in your way.

Regardless of your desktop choice, Fedora 18 offers...

  • Improved storage management SSM (System Storage Manager) is an easy-to-use command-line interface tool that presents a unified view of storage management tools. Devices, storage pools, volumes, and snapshots can now be managed with one tool, with the same syntax for managing all of your storage. (It's great for systems administrators, too!)

For developers

For developers there are several enticing new features:

  • Fresh versions of programming languages Using Perl, Rails, or Python? All three of these languages are updated in Fedora 18. We've got Rails 3.2, Python 3.3, and Perl 5.16 waiting for you.
  • Clojure Clojure gets more love with the addition of tooling packages, including the Leinengen build tool, as well as Clojure libraries and frameworks, including Korma and Noir.
  • DragonEgg optimizes GCC DragonEgg is a plugin for the GCC compilers to allow use of the LLVM optimization and code-generation framework. DragonEgg provides software developers with more optimization and code-generation options for use with the GCC compilers. DragonEgg also allows GCC to be used for cross-compilation to target architectures supported by LLVM without requiring any special cross-compilation compiler packages.

For systems administrators

Keep track of your infrastructure with these new features:

  • Offline system updates Systems can now be upgraded offline, allowing for a more stable upgrade of critical system components.
  • Storage enhancements StorageManagement is a collection of tools and libraries for managing storage area networks (SAN) and network attached storage (NAS).
  • Samba 4 This popular suite of tools has long provided file- and print-sharing services in heterogeneous operating system environments. The long-awaited Samba 4 introduces the first free and open source implementation of Active Directory protocols and includes a new scripting interface, allowing Python programs to interface to Samba's internals.
  • Riak A fault-tolerant key-value store, Riak provides easy operations and predictable scaling as a NoSQL database.

For clouds and virtualization

Here are just a few of the cloud and virtualization features you'll see in Fedora 18:

  • Eucalyptus Eucalyptus makes its first appearance in Fedora, with their 3.2 release included in F18. This platform for on-premise (private) Infrastructure-as-a-Service clouds uses existing infrastructure to create scalable and secure AWS-compatible cloud resources for compute, network, and storage.
  • OpenStack With the Folsom release in Fedora 18, OpenStack continues to have the newest releases in Fedora. This open source cloud computing platform enables users to deploy their own cloud infrastructures for private or public cloud deployments. Heat, an incubated OpenStack project, is also available in F18, providing an API that enables the orchestration of cloud applications using file or web based templates.
  • oVirt Engine The management application for the oVirt virtualization platform, oVirt Engine, is updated to the newest version, 3.1. This release includes extensive new features, including support for live snapshots, cloning virtual machines from snapshots, quotas, and more.
  • Suspend and resume support for virt guests Virtual machines get love with this feature, enabling the ability to suspend and resume guests, with the close of a laptop lid or menu option or via the command line.

And that's only the beginning. For a more complete list with details of all the new features in Fedora 18, visit:

Fedora 19

Even as we continue to provide updates with enhancements and bug fixes to improve the Fedora number experience, our next release, Fedora 19, is already being developed in parallel and has been open for active development for several months already. We have an early plan for release at the end of May 2013, and the final schedule for F19 is going to be based on the results of the planning process:

Feature Deprecation

Fedora has always been full of great features, but sometimes we need to cut a few. Here's what we cut out this time around:
