From the post - Five notable new features in Fedora Linux 18 'Spherical Cow'
1. The MATE desktop
The enduring popularity of GNOME 2 has
been striking in contrast, and we've
already seen numerous examples of
efforts to preserve the classic
desktop. Now, Fedora is offering a
like-minded option in the form of
MATE.
“This desktop is perfect for users who
have been running GNOME Classic or
other window managers like Xfce as an
alternative to GNOME 3,” the Fedora
team notes in the software's release
announcement.
Users of Fedora 18 actually have many
desktops to choose from, including
also Xfce 4.10, KDE Plasma Workspaces
4.9, Cinnamon, and GNOME 3.6.
2. A rewritten installer
Fedora's Anaconda installer has been
completely rewritten for this release
so as to make it easier to use for a
wider range of users.
A hub-and-spoke model, for instance,
makes installation easier for new
users, “offering them concise
explanations about their choices,” the
project team explains.
Other improvements include new visuals
to improve the overall look and feel
of the installation experience.
3. 'Secure Boot' support
The Fedora project was one of the
first distributions to recognize the
implications of the Secure Boot
technology enabled in Windows 8's
Unified Extensible Firmware Interface
(UEFI), and Fedora 18 is the first
release to include the fruits of its
labors. So, thanks to the software's
included UEFI Secure Boot support, it
can boot on systems that have Secure
Boot enabled.
Tools are also available that allow
administrators to create custom
certificates to sign local changes to
GRUB or the kernel, the release notes
point out.
4. Samba 4
Also notable particularly for systems
administrators is the inclusion of
Samba 4, the latest version of the
suite of tools that provide file- and
print-sharing services in
heterogeneous OS environments. Samba 4
goes even further than its
predecessors, in fact, by introducing
the first free and open source
implementation of Active Directory
protocols.
5. Eucalyptus
Last but not least is that Eucalyptus
makes its debut in Fedora 18, which
includes the cloud software's 3.2
release. Also included are OpenStack's
Folsom release and version 3.1 of the
oVirt engine.
