The Ubuntu team is pleased to announce the Release Candidate for Ubuntu
8.04 LTS (Long-Term Support) on desktop and server. Codenamed "Hardy
Heron", 8.04 LTS continues Ubuntu's proud tradition of integrating the
latest and greatest open source technologies into a high-quality,
easy-to-use Linux distribution.
We consider this release candidate to be complete, stable, and suitable for
testing by any user.
Ubuntu 8.04 LTS Desktop Edition features incremental improvements to
familiar applications, with an emphasis on stability for this second Ubuntu
long-term support release, and is easier than ever to try out with the new
Ubuntu 8.04 LTS Server Edition follows in the footsteps of Ubuntu 7.10 with
even more virtualization support and security enhancements - enabling
AppArmor for more applications by default, improving protection of kernel
memory against attacks, and supporting KVM and iSCSI technologies out of the
The Ubuntu 8.04 LTS family of variants, Kubuntu, Xubuntu, UbuntuStudio, and
Mythbuntu, also reach RC status today.
The final release of Ubuntu 8.04 LTS is scheduled for 24 April 2008 and will
be supported for three years on the desktop and five years on the server.

About The Release Candidate
The purpose of the Release Candidate is to solicit one last round of testing
before the final release. Here are ways that you can help:
* Upgrade from Ubuntu, Kubuntu, or Edubuntu 7.10 to the Release Candidate
by following the instructions given above.
* Participate in installation testing using the Release Candidate CD
images, by following the testing and reporting instructions at
Improved application selection: the GNOME desktop sports a number of
improvements to the default applications, including more feature-full
clients for BitTorrent and VNC, as well as an advanced UI for mastering CDs
File browsing: an enhanced filesystem layer brings greater performance and
flexibility to Nautilus, the GNOME file browser.
Pluggable audio and video output: the PulseAudio sound server is integrated
in the GNOME desktop for more flexible sound output, and a new Screen
Resolution utility allows easier configuration of multiple video displays.
Wubi installer: a new Windows-based installer option makes it easier than
ever to try out Ubuntu, letting users install a full desktop on Windows
systems without needing to partition their hard drive.
AppArmor profiles: a greater number of server applications are now protected
by default with AppArmor, a kernel technology that limits the resources an
application is allowed to access, providing added protection against
undiscovered security vulnerabilities.
Memory protection: additional protection now prevents direct access to
system memory through /dev/mem and /dev/kmem, and the lower 64K of system
memory is no longer addressable by default, changes which help to defend
against malicious code. The kernel now also loads Position Independent
Executables at randomized addresses, making it harder for application
security vulnerabilities to be exploited.
Virtualization and iSCSI: KVM is now an officially maintained option, which
combined with libvirt (CLI) and virt-manager (GUI) management tools allows
for a simple and efficient virtualization option on hardware that supports
virtualization extensions (AMD-V or Intel-VT). Mounting iSCSI targets is
now supported (including in the installer), allowing Ubuntu to interoperate
with this class of cost-efficient Storage Area Network solutions.
Ubuntu Education Edition
Add-on configuration: Edubuntu is now provided as an add-on to Ubuntu
rather than a separate stand-alone flavor, permitting even greater reuse
of Ubuntu technologies.
Kubuntu comes with the rock solid KDE 3 for those who want a commercially
For those who want something more exciting, a KDE 4 Remix is available
bringing this cutting edge new version to you first.
Please see https://wiki.kubuntu.org/HardyHeron/RC/Kubuntu for details.
Xubuntu comes with the light-weight Xfce 4.4.2 desktop environment for those
who want to a desktop that is easy to use, but places particular emphasis on
conserving system resources.
New additions to the family
Two new variants join us for this Ubuntu release. UbuntuStudio and
Mythbuntu have done releases separately in the past, and with Hardy Heron
we're happy to be able to welcome these fine community projects into the
main Ubuntu release process.

Ubuntu is a full-featured Linux distribution for desktops, laptops, and
servers, with a fast and easy install and regular releases. A
tightly-integrated selection of excellent applications is included, and
an incredible variety of add-on software is just a few clicks away.
