2.1. Fedora 之旅
You can find a tour filled with pictures and videos of this exciting new release at http://fedoraproject.org/wiki/Tours/Fedora9.
2.2. Fedora 新增内容
本次发布包括很多关键软件包和技术的新版本。下面的章节对自前一版本以来的主要更改做出概览。
2.2.1. 发布集(Spins)
Fedora 包括多种发布集(spins)，这是使用特定软件包集合产生的 Fedora 变种。每个发布集都通过软件包的组合来适应特定用户的需求。除网络安装时使用的很小的 boot.iso 镜像之外，用户可以在下列发布集中选择：
通常的 Fedora 镜像，适于桌面、工作站和服务器用户。这一发布集为过去版本 Fedora 的用户提供了良好的升级路径和熟悉的环境。
One of several Live images that can be run from a disc or USB flash device, and can be installed to hard disk as desired. Refer to the "Live" section for more information about the Live images.
More custom spins are available at http://spins.fedoraproject.org. These Live images can be used on USB media via the livecd-iso-to-disk utility available in the livecd-tools package.
2.2.2. Jigdo
Fedora releases are also available via Jigdo. This distribution method can improve the speed of obtaining the installation ISO images. Instead of waiting for torrent downloads to complete, Jigdo seeks the fastest mirrors it can find via the Fedora Project Mirror Manager infrastructure, and downloads the bits it needs from these mirrors. To optimize seeking these bits, you can tell Jigdo to scan a DVD or CD you already have, and cut down on redundant downloads. This feature becomes particularly useful if you:
Download all the test releases and then get the final release, in which case you have 90% of the data already with each subsequent download.
Download both the DVD and the CD set, in which case the DVD holds 95% of the data needed for the CD sets.
Download any combination of the above.
2.2.3. 特性
This release features GNOME 2.22. GNOME now includes a webcam photo and video creation utility called Cheese, improved network filesystem support, a new international clock applet, Google Calendar support and custom email labels in Evolution, a new Remote Desktop Viewer, improved accessibility features, and PolicyKit integration.
Online Desktop provides a desktop experience designed around online services. A preview of Online Desktop is provided via BigBoard, which is a optional sidebar in GNOME.
KDE 4.0.2 is available in the KDE Live image as well as the regular DVD.
Xfce 4.4.2 作为发布的一部分。
NetworkManager 0.7 provides improved mobile broadband support, including GSM and CDMA devices, and now supports multiple devices and ad-hoc networking for sharing connections.
PulseAudio is now installed and enabled by default. PulseAudio is an advanced sound server compatible with nearly all existing Linux sound systems. PulseAudio allows for hot-switching audio outputs, individual volume controls for each audio stream, networked audio, and more.
Compiz, the compositing window manager that brings eye candy and usability improvements to the desktop, is installed by default, and is easily enabled by both GNOME and KDE users via the → → tool from the Fedora team. While Compiz is not yet robust or mature enough to be enabled by default, ongoing, long term X.Org work by Fedora developers continues. The expectation is that Fedora is going to enable Compiz by default in the next release.
Compiz Fusion, which re-merges Compiz and Beryl, is also available in the Fedora software repository. Users can easily install Compiz Fusion via → tool or with yum.
The Fedora installer, Anaconda, now supports independent locations for the second stage installer and the software packages. A redesigned, larger
boot.isoimage now features a second stage installer partly for this reason.The completely free and open source Java environment OpenJDK 6 is installed by default. IcedTea 7, derived from OpenJDK 1.7, is no longer the default. IcedTea includes a browser plugin based on GCJ, and is available for both x86 and x86_64 architectures. GCJ is still the default on PPC architecture.
OpenOffice.org 2.4, with many new features, is available as part of Fedora 9.
Bluetooth 设备和工具有更好的图形化和系统整合。
Laptop users benefit from the "quirks" feature in HAL, including better suspend/resume and multimedia keyboard support.
The
swfdecpackage, which decodes and renders Flash animations and videos, is now installed by default. However, many videos require additional codec support. Refer to http://fedoraproject.org/wiki/AdditionalCodecs for more information.Fedora now includes Perl 5.10.0, which features a smaller memory footprint and other improvements.
Eclipse 3.3.1 is available as part of this release.
PackageKit, a new set of graphical and console tools for cross-distribution software management, is installed by default in this release of Fedora. The PackageKit graphical updater is also installed by default, instead of Pup. Behind PackageKit , the performance of
yumhas been significantly improved. Pup and Pirut are still available in the software repositories for users that prefer them.Transifex provides a web-based translation interface to allow users to contribute translation work for Fedora hosted projects as well as being able to provide translations directly to any upstream project.
Fedora now offers easier rebranding of Fedora derivatives via a generic-logos software package. Changes in Fedora's mirror structure also make creation of derivatives easier.
The
pam_consolemodule usage has been removed in favor of access control via HAL, which modernizes the desktop.在GNOME桌面中，输入法现在能够动态被启动和停止。
This release of Fedora uses Upstart, an event-based replacement for the
/sbin/initdaemon.Fedora now includes TeXLive to replace the older, unmaintained TeX distribution.
Fedora 包含内核的 2.6.24 版本。
Work on the start-up and shutdown in X has yielded noticeable improvements.
