We are proud to announce the official release of Fedora 22 for
IBM z Systems, the community-driven and community-built operating
system now available in Server edition.
If that's all you need to hear, jump over to Get Fedora to download
-- or for current users, run the FedUp upgrade tool.
In addition to the latest versions of all your favorite free and
open source software, Fedora 22 marks our second release with
distinctly-targeted offerings for cloud computing, and the server
room. Thanks to the hard work of developers, designers, packagers,
translators, testers, documentation writers, and everyone else,
we're incredibly confident in saying that this is our best and
most polished release yet.
Also with this release, we return to our traditional six-month
cadence -- we'll see you back here sometime around Halloween!
Highlights in the Fedora 22 release
Every Fedora release has its own character. If this release had a
human analogue, it'd be Fedora 21 after it'd been to college,
landed a good job, and kept its New Year's Resolution to go to the
gym on a regular basis. What we're saying is that Fedora 22 has
built on the foundation we laid with Fedora 21 and the work to
create distinct editions of Fedora focused on the desktop, server,
and cloud (respectively). 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.
* Database Server Role -- The Fedora Server edition focuses on easy of
different server roles. Fedora 21 debuted with an Domain Controller
Role featuring FreeIPA. For this release, we've added a Database
Server role, built around PostgreSQL.
* Default to XFS filesystem -- The default file system type for
Fedora Server installs will be XFS running atop LVM for all
partitions except /boot. The /boot partition will remain a non-LVM,
ext4 partition due to technological limitations of the bootloader.
* Cockpit will be compatible between OS releases -- Cockpit is a
server manager that makes it easy to administer your GNU/Linux
servers via a web browser.
- Easy to use. Cockpit is perfect for new sysadmins, allowing
them to easily perform simple tasks such as storage
administration, inspecting journals and starting and stopping
- No interference. Jumping between the terminal and the web
tool is no problem. A service started via Cockpit can be
stopped via the terminal. Likewise, if an error occurs in the
terminal, it can be seen in the Cockpit journal interface.
- Multi-server. You can monitor and administer several servers
at the same time.
Other changes of note
Faster and better dependency management with DNF
With Fedora 22, we're introducing a major change under the hood.
Specifically, we're now using DNF and hawkey to manage packages.
DNF is much like the Yum software package manager (it's largely
command-line compatible), but re-written and re-engineered to
provide optimal performance and (along with Hawkey) provide a
strict API definition for plugins and extending projects. DNF also
makes use of the libsolv library initially pioneered by the
openSUSE Project to provide faster and better dependency
It also boasts a better performance and memory footprint vs. Yum,
and is designed to have a cleaner codebase and be easier to
If you're using the Fedora 22 Workstation edition, and managing
packages with the Software Application, odds are you won't notice a
difference. Server and Cloud users who fall back on Yum commands
will receive a reminder (courtesy of dnf-yum) that Yum is
deprecated and DNF is now the default package manager. DNF has been
in development for quite some time, so we're confident it's ready
for prime time. The classic Yum command line tool has been renamed
to yum-deprecated as a transitional step for tools still using it.

GNU Compiler Collection 5
Fedora 22 comes with GCC 5.1 as the primary compiler suite.
