The Fedora 16 "Verne" Alpha release is available! This release offers a
preview of some of the best free and open source technology currently
under development. Catch a glimpse of the future:
== What is the Alpha release? ==
The Alpha release contains all the exciting features of Fedora 16 in a
form that anyone can help test. This testing, guided by the Fedora QA
team, helps us target and identify bugs. When these bugs are fixed, we
make a Beta release available. A Beta release is code-complete, and
bears a very strong resemblance to the third and final release. The
final release of Fedora 16 is due in early November.
We need your help to make Fedora 16 the best release yet, so please take
a moment of your time to download and try out the Alpha and make sure
the things that are important to you are working. If you find a bug,
please report it -- every bug you uncover is a chance to improve the
experience for millions of Fedora users worldwide. Together, we can make
Fedora a rock-solid distribution. (Read down to the end of the
announcement for more information on how to help.)
This release of Fedora includes a variety of features both over and
under the hood that show off the power and flexibility of the advancing
state of free software. Examples include:
* System Boot. Fedora 16 introduces GRUB2, the long-awaited
next-generation boot-loader for Linux. GRUB2 automatically recognizes
other operating systems, supports LVM2 and LUKS partitions, and is more
customizable than the previous version. In this release, only x86
systems with a BIOS uses GRUB2 by default. Work is ongoing for making
GRUB2 the default for other architectures and systems.
* Services Management. Fedora 15 introduced the Systemd services
management program. This release features better integration of Systemd
via conversion to native systemd services from legacy init scripts in
many software components -- for desktop users, this means faster boot
times; for system administrators it means more powerful management of
* Desktop Updates. The two major desktop environments have been
updated to the latest releases: KDE Software Compilation 4.7 and GNOME
3.1 development release.
* SELinux Enhancements. SELinux policy package now includes a
pre-built policy that will only rebuild policy if any customizations
have been made. A sample test run shows 4 times speedup on installing
the package from 48 Seconds to 12 Seconds and max memory usage from 38M
to 6M. In addition to that, SELinux file name transition allows better
policy management. For instance, policy writers can take advantage of
this and write a policy rule that states, if a SELinux unconfined
process creates a file named resolv.conf in a directory labelled etc_t,
the file should get labeled appropriately. This results is less chances
of mislabeled files. Also, from this release onwards, selinuxfs is
mounted at /sys/fs/selinux instead of in /selinux. All the affected
components including anaconda, dracut, livecd-tools and policycoreutils
have been modified to work with this change.
* System Accounts. Fedora now standardizes on login.defs as
authority for UID/GID space allocation, and has moved boundary between
system and user accounts from 500 to 1000 to match conventions followed
by several other Linux distributions. Upgrading from a existing release
will not be affected by this change and you can use kickstart to
override this change during installation if necessary.
* Chrony NTP. Fedora has switched over to using Chrony as the
default NTP client. There are several advantages including smaller
memory footprint (1.3MB vs 6MB resident size), no unnecessary process
wakeups which results in better power savings. better timekeeping on
systems not running 24/7 or without permanent internet connection or
with low quality/unstable clocks (virtual machines). Once the clock is
synchronized, applications are not upset by backward time jumps.
system-config-date and GNOME settings daemon has been modified to use
Chrony as well.
* HAL Removal. HAL, a hardware abstraction layer which has been a
deprecated component for several releases, has been completely removed
from all Fedora spins and DVD. Software components using HAL have moved
over to using udisks and upower as well as libudev for device discovery.
This results in faster system bootup and faster startup for applications
depending on device discovery.
* Cloud Updates. Fedora now includes a number of new and improved
features to support cloud computing, including a "cloud ready" version
of GlusterFS, including additional auth*/crypto/multi-tenancy;
pacemaker-cloud, application service high availability in a cloud
environment; Condor Cloud, an IaaS cloud implementation using Condor and
the Deltacloud API, and Aeolus.
* Virtualization. Once again Fedora raises the bar on
virtualization support, including expanded virtual network support, an
improved Spice for managing virtual machines, restored Xen support, a
new virtual machine lock manager, and improved ability to browse guest
* Developer Improvements. Developers get many goodies with Verne,
including updated Ada, Haskell and Perl environments, a new Python
plugin for GCC and a number of new and improved APIs.
These and many other improvements provide a wide and solid base for
future Fedora releases. This release increases the range of
possibilities for developers and helps Fedora to maintain its position
at the leading edge of free and open source technology.
