Announcing Fedora 23

Fedora Project is pleased to announce the immediate release of Fedora 23, the latest incarnation of our community-built Linux-based operating system.

A year ago, we had our first release to feature three different editions — Fedora Workstation, Fedora Server, and Fedora Cloud — each custom-fit for your needs in these different areas. Versions are also available in Spins, Labs, Arm. Now, we're pleased to bring you the latest main versions of each of these.

Fedora Workstation

If you're a laptop or home user, hobbyist, enthusiast, student, or a software developer, Fedora Workstation is perfect for you. Fedora Workstation includes the newest release of the GNOME desktop, which makes your everyday computing simple, polished, and pleasant. Experience the sleek interface and powerful tools for yourself -- download Fedora Workstation now!

Fedora Server

Fedora Server makes service management simple with RoleKit, a programmatic interface for quick deployment, and Cockpit, a remote web GUI. Now in Fedora Server 23, you can manage Kubernetes clusters from the Cockpit Admin Console, or launch a FreeIPA domain controller from a kickstart file. Get Fedora Server this morning and have an identity management solution in place by lunchtime.

Fedora Cloud

Build scale-out computing with Fedora Cloud. The Fedora Cloud Base image provides a minimal OS platform which can be downloaded for use in OpenStack, or launched directly into EC2. Fedora Atomic Host takes things in a more radical direction, providing a specialized system for running Docker containers and Atomic Apps. Now with Fedora 23, Fedora Atomic host will be updated on a two-week cycle to keep at the edge of emerging technology.

Spins, Labs, and ARM

Fedora is also available for several purpose:

Fedora Spins are alternative desktops for Fedora that provide a different experience than the standard Fedora Workstation edition. For instance, the Fedora KDE and Fedora Xfce spins provide popular alternatives to GNOME for Fedora users who enjoy the KDE or Xfce experience.

There's a new spin in town for Fedora 23. Want a classic take on a modern desktop? If so, the Cinnamon spin may just be what you're hoping to find. Fedora 23 includes a spin that tries to emulate the GNOME 2 experience using GNOME Shell from GNOME 3.x. Learn more at Cinnamon.

Sugar on a Stick is a stand-alone implementation of the desktop environment originally designed for the One Laptop per Child project. Fedora's SoaS spin has been updated to Sugar 0.106, for better performance, updated activities, and a new "social help" feature for collaborative learning. Get Fedora 23 Spins.

Fedora Labs are curated software collections. You can find updated live media focused on Games, Design, Robotics, and more. Get Fedora 23 Labs.
suitable for ARM-based computers used as servers, typically in a headless environment.Get Fedora 23 Arm.

Release history

As usual the Community began to work on Fedora 23 immediately after the previous release. which don't mean the planning started exactly in those days. Fedora is community-driven, so most the people working on improvements is multitasking with a peek on the current release and another focused on the future. The Alpha and Beta releases went very well and since the start were really stable therefore the testing period went smoothly mainly because the QA Team did a great work and developers were careful to detect and resolve issues in advance. In order to keep high the quality of Fedora 23, the GO/NO-GO meeting held on [1] established a one week delay because of some issues that a final user don't have to suffer. This is the proof that the Project is focused towards the user and the usability of its OS.

User Point of View: Improvements

  • The Workstation release is shipped with Gnome 3.18 and the first relevant improvement for a user is due to the possibility of accessing the files stored in Google Drive by Nautilus just enabling the online accounts (if not done in the first time logging, the online account can be handled from the settings widgets), The access will granted immediately and a icon (just like a network one) will be placed in the left bar.
  • For the VM lovers, Boxes now allows to filter remote or local boxes, and their visual has been improved as well. Other improvements (generally adaptations) have been introduced to facilitate some actions.
  • Of course one of the best pleasant surprises is related to the introduction of LibreOffice 5 which brings with it an increased accuracy in importing files from others suite and an enhancement of Calc complex formulas.
  • There is, also, a further step ahead for the next Fedora X server: Wayland
  • In general applications had some graphic enhancements.

System Point of View: Improvements

Fedora-Wide Changes

Fedora 23 includes a number of changes that will improve all of the editions. For example, Fedora 23 makes use of compiler flags to improve security by "hardening" the binaries against memory corruption vulnerabilities, buffer overflows, and so on. This is a "behind the scenes" change that most users won't notice through normal use of a Fedora edition, but will help provide additional system security.

Likewise, Fedora 23 has disabled SSL3 and RC4 by default due to known vulnerabilities in the protocols. This means all applications that use GNUTLS and OpenSSL libraries have had the SSL3 protocol and RC4 cipher disabled.

Fedora 23 comes with the latest version of Mono 4. This means a big improvement because we were stuck with an ancient version of Mono (2.10) for too long. All packages within Fedora that are based on Mono have been adjusted and rebuilt, to target the 4.5 version of the .Net framework. Mono 4 does not support solutions targeting v1.0, v2.0 or v3.5 of .Net, but usually they can be easily upgraded to v4.5.

Fedora 23 also includes support for Unicode 8.0, which includes new emojis, and improvements in sorting Unicode text and processing non-ASCII URLs.

Fedora Server

The Fedora Server release includes a number of interesting changes and additions.

The rolekit service now supports setting up three roles. In addition to the previously supported Domain Controller (powered by FreeIPA abd Database Server (powered by PostgreSQL) roles, Fedora Server 23 features a cache server for web applications (powered by memcached).

Rolekit can also now be used from the anaconda kickstart by passing the --deferred arguments to rolectl. For example: rolectl deploy domaincontroller --deferred will instruct the system to deploy the Domain Controller role on the next boot.

The Cockpit Admin Interface in Fedora Server has several big improvements as well.

  • Support for SSH key authentication
  • Support for configuring user accounts with their authorized keys.
  • Basic cluster dashboard for driving Kubernetes on Fedora Server and Fedora Atomic Host.
  • Set the timezone for your Fedora Server from the Cockpit User Interface (UI).
  • Cockpit has also been made safe to use with multipath disks.

Fedora Workstation

While there's a lot going on under the hood, desktop users are also going to find Fedora 23 pretty exciting for all the obvious goodness coming to the desktop. The easiest way to experience the preview of these technologies is to download and try the Fedora 23 Workstation edition.

Naturally, GNOME is getting an upgrade, with Fedora 23 containing a preview of the upcoming GNOME 3.18 release, which is easier to use than ever. There are also many enhancements on the way, such as:

  • Improvements to next-generation graphics stack Wayland, preparing it to be the default graphical server in a future release.
  • Support for ambient backlight drivers, so brightness responds to the environment on laptops with the required hardware
  • The Software application is smarter about metered Internet connections, and can now update system firmware
  • Refreshed support for Google APIs to provide access to user data through GNOME apps (including Google Drive integration)

Users trying to get a little work done on Fedora will be happy to see LibreOffice 5 in Fedora 23. The new release includes a lot of new features and improvements:

  • Style previews in the sidebar
  • Microsoft Word-compatible text highlighting
  • Built-in image crop
  • UI for data bars in Calc
  • Support for Time-Stamp Protocol in PDF export
  • Support for Adobe Swatch Exchange color palettes
  • Import of Apple Pages files
  • Improved support for HiDPI screens
  • Significantly improved support for MS Office formats

Fedora Cloud

Fedora 23 Cloud Base image includes many updates and enhancements to the underlying Fedora base packages. For example, Fedora 23 now has the latest Docker release, docker 1.8. We can now verify the publisher of an image before running. This gives the users the power to identify that the image publisher published has not been tampered with. You can find many other details about the newest Docker in this [ announcement ].

Stay tuned for news about Fedora Atomic Host in the not too distant future!

Other changes of note

Every software written in Python shipped by default on Fedora Workstation DVD and Fedora Cloud images is now running on Python3. Fedora Workstation doesn't even include Python2 in the default installation (it is still possible to install Python2 through dnf). Note that /usr/bin/python binary remains unchanged and still points to Python2.

Issues and Details

To report issues encountered during testing, contact the Fedora team via the users mailing list or in #fedora on freenode.

As testing progresses, common issues are tracked on the Common F23 Bugs page.
