Fedora 20 ´Heisenbug´ Alpha

Fedora è una distribuzione GNU/Linux curata dal Progetto Fedora, un progetto Open Source sponsorizzato (ma non direttamente supportato) da Red Hat e supportato dalla community.

Note di rilascio:

The Fedora 20 "Heisenbug" alpha release has arrived with a preview of

the latest fantastic, free, and open source technology currently under

development. Take a peek inside:

*** What is the Alpha Release? ***

The Alpha release contains all the exciting features of Fedora 20 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 20 is expected in early December.

We need your help to make Fedora 20 the best release yet, so please

take some 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. We have a culture of coordinating new features

and pushing fixes upstream as much as feasible and your feedback will

help improve not only Fedora but Linux and free software on the whole.

(See the end of this announcement for more information on how to help.)

*** Changes ***

Fedora prides itself on bringing cutting-edge technologies to users of

open source software around the world, and this release continues that

tradition. No matter what you do, Fedora 20 has the tools you need to

help you get things done.

To see how Fedora 20 is evolving from Fedora 19, see the accepted

changes here:

== 10 Years of Fedora ==

The Fedora 20 release coincides nicely with the 10th anniversary of

Fedora. The first Fedora release (then called Fedora Core 1) came out

on November 6, 2003.

Since then, the Fedora Project has become an active and vibrant

community that produces nearly a dozen "spins" that are tailor made for

desktop users, hardware design, gaming, musicians, artists, and early

classroom environments.

== ARM as a Primary Architecture ==

While Fedora has supported a number of hardware architectures over the

years, x86/x86_64 has been the default for the majority of Fedora users

and for the Linux community in general.

ARM, however, has been making massive strides. It already dominates the

mobile market, and is becoming a go-to platform for hobbyists and

makers, and is showing enormous promise for the server market as well.

In keeping with Fedora´s commitment to innovation, the Fedora community

has been pushing to make ARM a primary architecture to satisfy the

needs of users and developers targeting the ARM platform

*** Maturity and Advanced Features ***

Sometimes it´s not the big new features that make a users´ experience

better, it´s the little enhancements or long-awaited tricky features

that really help make a new release the bee´s knees.

=== NetworkManager Improvements ===

NetworkManager is getting several improvements in Fedora 20 that will

be welcome additions for power users and system administrators.

Users will now be able to add, edit, delete, activate, and de-activate

network connections via the nmcli command line tool, which will make

life much easier for non-desktop uses of Fedora.

NetworkManager is also getting support for bonding interfaces and

bridging interfaces. Bonding and bridging are used in many enterprise

setups and are necessary for virtualization and fail-over scenarios.

=== No Default Sendmail, Syslog ===

Fedora 20 removes some services that many users find unnecessary,

though (of course) they will remain available as installable packages

for users who might need them.

The systemd journal now takes the place as the default logging

solution, having been tested and able to manage persistent logging in

place of syslog.

Also, Sendmail will no longer be installed by default, as most Fedora

installs have no need of a Mail Transfer Agent (MTA).

== Cloud and Virtualization Improvements ==

The Fedora 20 release continues the Fedora tradition of adopting and

integrating leading edge technologies used in cloud computing. This

release includes a number of features that will make working with

virtualization and cloud computing much easier.

* OS Installer Support for LVM Thin Provisioning: LVM has introduced

  thin provisioning technology, which provides greatly improved

  snapshot functionality in addition to thin provisioning capability.

  This change will make it possible to configure thin provisioning

  during OS installation.

* VM Snapshot UI with virt-manager: This change will make taking VM

  snapshots much easier. qemu and libvirt have all the major pieces in

  place for performing safe VM snapshots/checkpoints, however there

  isn´t any simple discoverable UI. This feature will track adding that

  UI to virt-manager, and any other virt stack bits that need to be

  fixed/improved. This includes adding functionality to libvirt to

  support deleting and rebasing to external snapshots.

* Role based access control with libvirt: Libvirt role based access

  control will allow fine grained access control like ´user FOO can

  only start/stop/pause vm BAR´, but for all libvirt APIs and objects.

* ARM on x86 with libvirt/virt-manager: This change will fix running

  ARM VMs on x86 hosts using standard libvirt tools libvirt virsh,

  virt-manager and virt-install.

== Developer Goodness ==

As always, Fedora 20 will include several new features and updated

packages that will be of interest to all manner of developers.

* Ruby on Rails 4.0: This update will keep Fedora up-to-date and will

  ensure that the current Ruby on Rails developers stay with us as they

  will get support for system-packaged Ruby on Rails of the latest

  version. Apart from that, Rails 4.0 also bring improved

  functionality, speed. security and better modularization.

* Perl 5.18: Perl 5.18 will be shipped in Fedora 20. Perl doesn´t get

  as much attention these days, but it´s still a vital part of many

  production and development environments. Fedora will deliver the most

  up-to-date Perl release so its users will be able to stay current

  with the latest Perl.

*** Desktop Environments and Spins ***

= GNOME 3.10 =

Fedora 20 Alpha will have a preview of GNOME 3.10, GNOME 3.9.90. GNOME

3.10 will have a number of new applications and new features that will

please GNOME-lovers in the Fedora 20 release. This release includes a

new music application (gnome-music), a new maps application

(gnome-maps), a revamp for the system status menu, and Zimbra support

in Evolution.

There is also preliminary support in this release for running

GNOME-shell as a Wayland compositor, though Wayland may not be in the

default packages for the final Fedora 20 release.

= KDE Plasma Workspaces 4.11 =

The Fedora KDE SIG has rebased to KDE 4.11 for Fedora 20. This release

includes faster Nepomuk indexing, improvements to Kontact, KScreen

integration in KWin, Metalink/HTTP support for KGet, and much more.

= Spins =

Spins are alternate versions of Fedora. In addition to various desktop

environments for Fedora, spins are also available as tailored

environments for various types of users via hand-picked application

sets or customizations.

To see all of the Official Fedora 20 Release Spins, visit the Fedora 20

Release Spins page:

Nightly composes of alternate Spins are available here:

*** Note on Performance ***

Fedora development releases use a kernel with extra debug information

to help us understand and resolve issues faster; however, this can have

a significant impact on performance. Refer to the kernel debug strategy

page for more details:

You can boot with slub_debug=- or use the kernel from nodebug

repository to disable the extra debug info.

*** Issues and Details ***

Heisenbug Alpha is a testing release. To report issues encountered

during testing, contact the Fedora QA team via the test mailing list or

in #fedora-qa on freenode.

As testing progresses, common issues are tracked on the Fedora wiki:

For tips on reporting a bug effectively, read "How to File a Bug

Report:" .

** Contributing ***

There are many ways to contribute beyond bug reporting. You can help

translate software and content, test and give feedback on software

updates, write and edit documentation, design and do artwork, help with

all sorts of promotional activities, and package free software for use

by millions of Fedora users worldwide. To get started, visit today!
