Release Overview

As always, Fedora continues to develop and integrate the latest free and open source software. The following sections provide a brief overview of major changes from the last release of Fedora. For more details about other features that are making their way into Rawhide and set for inclusion in Fedora 12, refer to their individual wiki pages that detail feature goals and progress. Also, throughout the release cycle, there are interviews with the developers behind key features giving out the inside story. Features for this release are tracked on the feature list page.

The Purpose of the Alpha Release

This release is an installable, testable version of the code and features being developed for Fedora 12 (Constantine). The software is going to have bugs, problems, and incomplete features. It is not likely to eat your data or parts of your computer, but you should be aware that it could.

You have an important part to play in this release. Either install or run a Fedora Live instance of the Fedora 12 Alpha release, then try using a few applications or activities that are important to you. If it doesn't work, file a bug. This release gives the wider community a set of code to test against as a very important step in the process of making a solid Fedora 12 release. You can make the Fedora 12 release better by testing this release and reporting your findings.

What's New in Fedora 12 (Constantine) Alpha

The following sections document major new features and changes in the Fedora 12 Alpha release.

Thusnelda - Next Generation Open Video Codec

In support of Free Culture, the open web and to reduce the hold of proprietary and patent encumbered codecs, Red Hat has been sponsoring improvements on the open Ogg Theora video codec implementation codenamed Thusnelda via Christopher Montgomery (xiphmont), who created the format and work has resulted in drastic improvements to the codec. This release features this next generation codec. All applications using libtheora library including all the Gstreamer applications will automatically and transparently be taking advantage of the improvements. More details here.

GRUB with Ext4 Support

Fedora 9 originally included experimental support for Ext4 and Fedora 11 included Ext4 by default however GRUB in that version did not support Ext4 and hence required a separate boot partition formatted as Ext3 or Ext2. Fedora 12 now includes a updated version of GRUB with Ext4 support. Anoconda, the Fedora installer will permit this as well.

Dracut - New Booting System

Up until Fedora 10, the boot system (initial ram disk or initrd) used to boot Fedora was monolithic, very distribution specific and didn't provide much flexibility. This has been replaced with Dracut, a initial ram disk with a event based framework designed to be distribution independent. It has been also adopted by the Fedora derived OLPC project's XO operating system. OLPC modules for Dracut is available in the Fedora repository.

Bluetooth Service On Demand

In order to support bluetooth devices, bluetooth background service was started by default in previous versions of Fedora. In this release, bluetooth service is started on demand when needed and automatically stops 30 seconds after last device use instead reducing initial startup time and resources.

GNOME 2.28

The GNOME 2.28 development snapshot is part of this release, and is the default environment used in the Fedora Desktop Live image. The Desktop Live image is a downloadable CD you can use to test the new GNOME environment with or without installing it. The image can be written to CD, or to a USB flash disk using these instructions.

Gnote is installed by default in GNOME for this release replacing Tomboy. Gnote is a port of Tomboy from Mono to C++ and consumes fewer resources. Gnote is both an applet that can sit in your GNOME panel as well as a individual application you can run within other desktop environments. Fedora Desktop Live CD since the Fedora 10 release has excluded Mono and hence Mono based applications like Tomboy due to lack of space. Gnote will be installed by default in the Live CD as well in this release. Tomboy is still available as a optional alternative. If you are upgrading from the previous release you will not be migrated to Gnote and will continue to have Tomboy. Tomboy users can migrate easily to Gnote as it shares the file format and a plugin is available in Gnote that will automatically import Tomboy notes on first run. Many of the Tomboy plugins have been ported to Gnote. Following plugins are available as part of Gnote

  • Bugzilla Links
  • Tomboy Importer
  • Fixed Width
  • Insert Timestamp
  • Export to HTML
  • Printing Support
  • Sticky Notes Importer
  • Backlinks


If required, you can copy the notes from Tomboy to Gnote using the following command in your home directory


cp -r .tomboy .gnote

The sticky notes applet is not provided anymore since Gnote provides a better note taking utility and is available by default in this release.

Empathy replaces Pidgin as the default instant messenger in GNOME. Empathy is better integrated with GNOME and provides audio and video functionality for XMPP/Jabber users with more improvements planned. Empathy supports important accounts from Pidgin on first run so users can migrate more easily. Users upgrading from a previous release will continue to have Pidgin by default. Pidgin continues to be available in the repository and is actively maintained.

Epiphany in this release is now using the WebKit engine instead of the Gecko engine from Firefox. If you have issues, do report them via bugzilla.

KDE 4.3

KDE 4.3 is part of this release and is the default environment in the Fedora KDE Desktop Live image. The KDE Desktop Live image is a downloadable CD you can use to test the new KDE environment with or without installing it. The image can be written to a CD, or to a USB flash disk using these instructions.

Firefox 3.5.1

Firefox 3.5 pre-release was included in Fedora 11 (Fedora 11 updates includes Firefox 3.5) and this release now includes the general release with many improvements.

PHP 5.3.0

PHP 5.3.0 is included in this release. Most PHP based web applications should work and others will emit E_DEPRECATED warning that has been disabled for production use. A number of applications have been already fixed upstream including phpmyadmin. Other applications will require changes due to incompatibilities with this new version.

Additional Information

How to Try Alpha

This release is accompanied by installable live CDs of both the GNOME and KDE desktops. With a Live CD users can perform testing and demonstration without installing any software to the hard disk. As this release is largely targeted at developers and contains many bleeding edge packages, this is the best method for less experienced users who want to get involved with testing. The Live CDs also have an option to install Fedora to the hard disk for the more intrepid users.

The best way to download this release is through BitTorrent -- visit the Fedora torrent server for a listing of available images. Release images can also be downloaded from any of our mirrors. Remember that live images can be used on USB media via the livecd-iso-to-disk utility available in the livecd-tools package on existing Fedora systems. Refer to the USB How-to for more instructions. You can also use Jigdo to download the i386, x86_64, or ppc versions.

Verify Fedora

Fedora does not publish MD5 or SHA1 hashes to verify images since they are not secure enough. Instead we have been using SHA256 since Fedora 11. In Linux, you can use sha256sum command (part of coreutils and installed by default) to verify the Fedora image


sha256 <ISO image filename>

Windows can use free for download utility called HashCalc. More details here

Fedora GPG signatures can be verified following the instructions here
