1.2. Overview

As always, Fedora continues to develop (RedHat contributions) and integrate the latest free and open source software (Fedora 14 Features). The following sections provide a brief overview of major changes from the last release of Fedora. For more details about other features that are included in Fedora 14 refer to their individual wiki pages that detail feature goals and progress:
The following are major features for Fedora 14:
  • Spice - Spice aims to provide a complete open source solution for interaction with virtualized desktops and provides high-quality remote access to QEMU virtual machines.
  • Mobility options - This release includes software from the MeeGo™ project which is designed to support platforms such as netbooks, nettops, and various embedded devices.
  • Amazon EC2 - For the first time since Fedora 8, Fedora will release on the EC2 cloud.
  • D Compiler - Support for D, a systems programming language. Its focus is on combining the power and high performance of C and C++ with the programmer productivity of modern languages like Ruby and Python.
Some other features include:
Updating Perl to version 5.12, Python to version 2.7, Boost to version 1.44, Netbeans to version 6.9, KDE to version 4.5, Eclipse to the Helios Release, and Sugar to version 0.90.

1.3. Hardware Overview

1.3.1. Processor and memory requirements for x86 Architectures

The following CPU specifications are stated in terms of Intel processors. Other processors, such as those from AMD, Cyrix, and VIA that are compatible with and equivalent to the following Intel processors, may also be used with Fedora. Fedora 14 requires an Intel Pentium Pro or better processor, and is optimized for i686 and later processors.
  • Recommended for text-mode: 200 MHz Pentium Pro or better
  • Recommended for graphical: 400 MHz Pentium Pro or better
  • Minimum RAM for text-mode: 256 MiB
  • Minimum RAM for graphical: 384 MiB
  • Recommended RAM for graphical: 512 MiB

1.3.2. Processor and memory requirements for x86_64 architectures

  • Minimum RAM for text-mode: 256 MiB
  • Minimum RAM for graphical: 384 MiB
  • Recommended RAM for graphical: 512 MiB

1.3.3. Hard disk space requirements for all architectures

The complete packages can occupy over 9 GB of disk space. Final size is entirely determined by the installing spin and the packages selected during installation. Additional disk space is required during installation to support the installation environment. This additional disk space corresponds to the size of /Fedora/base/stage2.img (on Installation Disc 1) plus the size of the files in /var/lib/rpm on the installed system.
In practical terms, additional space requirements may range from as little as 90 MiB for a minimal installation to as much as an additional 175 MiB for a larger installation.
Additional space is also required for any user data, and at least 5% free space should be maintained for proper system operation.

2. Изменения в Fedora для пользователей настольных компьютеров

2.1. Desktop Changes

2.1.1. Major package changes man to man-db package exchange
The package man is substituted by package man-db which provides similar functionality:
man description: The man package includes three tools for finding information and/or documentation about your Linux system: man, apropos, and whatis. The man application formats and displays on-line manual pages about commands or functions on your system. apropos searches the whatis database (containing short descriptions of system commands) for a string. The whatis searches its own database for a complete word.
man-db description : The man-db package includes five tools for browsing man pages: man, whatis, apropos, manpath and lexgrog. man preformats and displays manual pages. whatis searches the manual page names. apropos searches the manual page names and descriptions. manpath determines search path for manual pages. lexgrog directly reads header information in manual pages. Pino
Due to changes in Twitter's authentication mechanisms Pino is no longer able to utilize this service. Due to this degraded functionality, Pino has been removed as the default program for social networking services such as and Twitter. Other programs, such as gwibber, are available from the Fedora repositories that can utilized as a replacement for Pino. To install gwibber or another such package, use the SystemAdministrationAdd/Remove Software tool from the main menu.

2.1.2. KDE 4.5

Fedora 14 includes the updated KDE SC ("Software Compilation") version 4.5. The KDE developers worked on usability and stability for version 4.5. The result is a faster, easier, and more stable desktop experience. Many bugs are fixed and subtle but important improvements made to hidden components, so KDE now works the way you want. KDE Background Components
Some of the enhancements to background components include:
  • Phonon, the sound server for KDE applications, can now directly use the PulseAudio sound server.
  • An enhanced memory-cache feature that helps to speed up different applications using the same resources (like icons).
  • The WebKit web page rendering engine, as used in other popular web browsers like Safari and Chrome, is now available in Konqueror and other KDE applications. Konqueror also features improvements that enable it to load web pages faster. KDE Plasma Workspaces
Some of the enhancements to the "Plasma" desktop and netbook workspaces include:
  • An improved notification area and system tray. Application icons are now monochromatic, making them easier to see. Visual progress bars have been added to the widgets for long-running operations like file transfers and downloads.
  • The KWin window manager features many improvements:
    • You can add or remove virtual desktops in the "Desktop Grid" view.
    • You can lay out your windows without overlap by using the window-tiling feature.
    • You can move windows by dragging any empty area in the window, rather than just the title bar.
  • You can save and restore "activities," which are a set of plasma widgets. Use this feature to gather all of your social networking widgets in one activity, and all of your hardware monitor widgets in one activity, for example. KDE Applications
Some of the enhancements to background components include:
  • A new game, Kajongg, is a four-player version of mahjongg. This is the first KDE game to take advantage of the KDE programming language extensions for Python, which allow programmers to write software more easily and with fewer bugs.
  • The Marble desktop globe application has support for planning trips, based on OpenStreetmap and OpenRouteService. You can also load this information before you start on a trip, meaning that you can access map and route information even when you cannot access the internet.
  • The Gwenview document viewer now runs smoothly even while using processor-intensive visual effects. It is also more configurable and stable in all conditions. You can even share your pictures online more easily with the integrated Flickr upload feature.
  • The Dolphin file manager, and other KDE components, offer better integration with semantic meta-data provided by the Nepomuk Semantic Desktop.

2.1.3. LXDE

Lightweight X Desktop Environment, or LXDE, is available in Fedora 14.
Changes to LXDE include:
  • lxappearance has been updated to version 0.5. The "Look and Feel" configuration was completely rewritten and now supports many more features including setting mouse cursor themes, custom colors, icon sizes in menus and buttons, turning icons in menus and buttons on and off, and enabling event sounds.
  • The display manager lxdm has been updated to version 0.3.0. It now has a user list and a timeout, so we can select the language and the keyboard setting on the login window. This is very handy for the livecd.
  • lxterminal has been updated to version 0.1.9 and now has new features like true transparency for composite window managers.

2.1.4. MeeGo™

Fedora 14 contains a selection of software from the MeeGo™ project.
MeeGo™ is an operating environment and development kit for next-generation mobile and device platforms, formed from the merger of Intel's Moblin project and Nokia's Maemo project, and backed by the Linux Foundation. It includes a rich set of software and libraries that support multiple architectures and multiple app stores, and are well aligned with a variety of upstream free and open source software projects. Fedora 14 offers an integrated subset of software from the MeeGo project. Users can try the software on any personal computer, including netbooks or other small systems, and interested developers can contribute to the development of this exciting new platform. Note that a small portion of software from MeeGo is not included to improve integration with other Fedora applications, and therefore this subset is not expected to achieve 100% MeeGo compliance.

2.1.5. Sugar

Fedora 14 includes the latest Sugar Learning Environment (0.90), including an enhanced activity set to provide a stable demo environment for Sugar as well as an environment for developers.
This version provides major usability improvements for the first login screen and the control panel, as well as new features such as support for 3G networks.

3. Изменения в Fedora для системных администраторов

3.1. Безопасность

3.1.1. OpenSCAP Abstract
Fedora 14 brings in support of the SCAP (Security Content Automation Protocol). A library called OpenSCAP that provides development framework and several SCAP scanning tools are included in the distribution. OVAL and XCCDF contents specific for Fedora 14 that can be used for automated system configuration checking are also provided.

3.1.2. Description

OpenSCAP is an open-source framework for SCAP developers. SCAP is a line of standards managed by NIST (National Institute of Standards and Technology). It was created to provide a standardized approach to maintaining the security of systems, such as automatically verifying the presence of patches, checking system security configuration settings, and examining systems for signs of compromise.
The SCAP suite contains multiple complex data exchange formats that are to be used to transmit important vulnerability, configuration, and other security data. Historically, there have been few tools that provide a way to query this data in the needed format. The OpenSCAP project aims to create a framework of libraries to improve the accessibility of SCAP and enhance the usability of the information it represents.
The tools based on OpenSCAP library which are included in this Fedora feature are:
  • oscap-scan - command line scanner driven by OVAL/XCCDF content
  • secstate - tool that attempts to streamline the Certification and Accreditation (C&A) process of Linux systems by providing a mechanism to verify, validate, and provide remediation to security relevant configuration items.
  • firstaidkit-plugin-openscap - Plugin for FirstAidKit which allows user to perform basic automated security audit and evaluate the results in text or graphical environment.
With this feature installed, the user can use different ways to perform automatic scan of his system and make sure the system is in compliance with defined security configuration. The user is enabled to automatically remediate the system.

3.1.3. References

3.2. Виртуализация

It can gather FRU inventory data, SEL firmware log, sensors, watchdog, power control, health, monitoring, and has an SOL console. It can write sensor thresholds, FRU asset tags, and supports a full IPMI configuration save/restore. Ease-of-use examples with ipmiutil: configuring the IPMI LAN requires a single command, and a soft-reboot can be easily performed instead of a hard reboot. This utility can use various existing IPMI drivers, or run in driverless mode, which is useful for boot media or test environments. The decoding of IPMI events includes a severity, and any events not recognized at least return the data, rather than just Unknown. Features compared to other IPMI packages:

3.5. X Display System

3.5.1. vbetool not installed by default

Due to problems with vbetool, this package has been removed from the default installation of Fedora. This change may impact users with suspending and resuming their computers. These problems should only affect users of uncommon VGA adaptors and not users of nVidia, ATI, or Intel adaptors.

3.5.2. Mouse Behavior

The latest version of evdev, version 2.5, changed the default for the middle mouse button emulation code. This change has disabled emulation of the middle mouse button by clicking the left and right mouse buttons. Enabling the middle mouse button emulation

4. Изменения в Fedora для разработчиков

4.1. Development Overview

Fedora includes a wide range of tools for software development in all popular languages. This section highlights some of the new features in Fedora 14.

4.1.1. New Programming Language

Fedora 14 introduces support for D, a systems programming language combining the power and high performance of C and C++ with the programmer productivity of modern languages such as Ruby and Python.
For more details, refer to D Programming Language.

4.1.2. Support for GNUStep

The GNUstep development environment arrives on Fedora, allowing easy development of cross-platform applications on Fedora using the Cocoa (formerly NeXTSTEP/OpenStep) APIs and tools. GNUstep's main development language is Objective-C, but GNUstep is not limited to that.

4.1.3. Other improvements

  • Updates to the Python, Erlang and Perl languages and the Netbeans and Eclipse development environments.
  • The gdb debugger has been extended with new commands that make it easier to track down and fix excessive memory usage within programs and libraries, as well as an index that greatly speeds up debugging.
These features complete a rich set of development tools that further extends the possibilities for developers. For a complete list of the hundreds of updated development components see the Fedora 14 Technical Notes at

4.2. Runtime

4.2.1. boost

The boost C++ libraries have been upgraded to 4.4. which includes numerous changes. For details, see the release notes:
Some key features include new libraries for UML2 FSMs, Polygons, Factory and Forward adapters, and a UUID library. Existing libraries have been updated with many new features as well as performance improvements.

4.2.2. libjpeg-turbo

The libjpeg library has been replaced by libjpeg-turbo library which has same API/ABI but is at least twice faster on all primary architectures and about 25% faster on secondary architectures. For more details view libjpeg-turbo, on the Fedora wiki.

4.3. Development Tools

4.3.1. D Programming Language

D is a systems programming language. Its focus is on combining the power and high performance of C and C++ with the programmer productivity of modern languages like Ruby and Python. The D language is statically typed and compiles directly to machine code. It's multiparadigm, supporting many programming styles: imperative, object oriented, and metaprogramming. It's a member of the C syntax family, and its appearance is very similar to that of C++.
  • LLVM D Compiler
    LDC is a compiler for the D programming Language. It is based on the latest DMD frontend and uses LLVM as backend. LLVM provides a fast and modern backend for high quality code generation.
  • The library
    Tango is a cross-platform open-source software library, written in the D programming language for D programmers. It is structured as a cohesive and comprehensive library for general purpose usage, and is supported by a growing number of recognized D enthusiasts. Availability of solid and extensive documentation represents a prime factor in library accessibility, and thus this project is as much about documentation production as it is about top-notch functionality.
For more informations:

4.3.2. python

The system python 2 stack has been upgraded to 2.7. For a list of changes see Whats new in 2.7. Caveat: PyCObject and warnings
Python provides various APIs for use by C extension modules. One of these APIs, PyCObject, was deprecated in Python 2.7, but there are a number of key modules that have not yet been ported to its replacement.
By default, deprecation warnings are ignored, so this will not cause problems.
However, if the standard warnings settings are overridden, you may see problems with these modules. In particular, if warnings have been set to "error", it is possible to make the Python interpreter abort or even segfault when importing these modules.
If you need to enable errors-for-warnings, please also add an override so that a PendingDeprecationWarning is merely logged rather than raising an exception:
>>> import warnings
>>> warnings.simplefilter('error')
>>> warnings.simplefilter('default', PendingDeprecationWarning)

4.3.3. python-migrate

python-migrate was updated to version 0.6. Support for SQLAlchemy 0.6 and Firebird database, custom templates and use of python logging are among many new features. New version also introduces some backwards incompatible changes:
  • api.test() and schema comparison functions now all accept url as first parameter and repository as second.
  • python upgrade/downgrade scripts do not import migrate_engine magically, but receive engine as the only parameter to function (eg. def upgrade(migrate_engine):)
  • Column.alter does not accept current_name anymore, it extracts name from the old column.
For complete list of changes refer to the changelog

4.3.4. Erlang

New version of Erlang/OTP is available in Fedora 14. For details, view Erlang R14, on the Fedora wiki.

4.3.5. gdb

gdb has been enhanced to remove the unncecessary indices from the .debug files, and will replace them with an index that greatly speeds up gdb.
The gdb debugger has been extended with new commands that make it easier to track down and fix excessive memory usage within programs and libraries. This functionality was created by Fedora contributor David Malcolm, and we believe it is unique to Fedora 14.
For more informations, refer to Gdb Index, on the Fedora wiki.

4.3.6. GNUstep

This Feature offers the possibility to create GNUstep applications on Fedora. GNUstep is an open source reimplementation of Nextstep. It's provide an GUI framework base of the Objective-C programming language.
The Objective-C programming language is part of the GNU compiler collection (gcc).
A list of applications based on GNUstep you may find at List of GNUstep applications.
Detailed introduction to the GNUstep project you may find at GNUstep Introduction.

4.3.7. perl

Notable changes in perl 5.12 include:
  • Perl now conforms much more closely to the Unicode standard. Additionally, this release includes an upgrade to version 5.2 of the standard.
  • New experimental APIs allow developers to extend Perl with "pluggable" keywords and syntax.
  • Perl now has a better sense of time and will be able to keep accurate time well past the "Y2038" barrier.
  • New syntax allows developers to specify package version numbers directly in "package" statements
  • Perl now warns the user about the use of deprecated features by default.
Perl 5.12.x features numerous new features, optimizations and bugfixes. You can find a complete list of these changes on the web at:

4.3.8. rakudo

  • Details for the IRIX, Solaris 7, and Tru64 UNIX obsoletions can be found in the announcement.
  • Support for the classic POWER architecture implemented in the original RIOS and RIOS2 processors of the old IBM RS/6000 product line has been obsoleted in the rs6000 port. This does not affect the new generation Power and PowerPC architectures.
Support has also been removed for a number of features obsoleted in 4.4.

Reduced performance with C99 conformance

On x86 targets, code containing floating-point calculations may run significantly slower when compiled with GCC 4.5 in strict C99 conformance mode than they did with earlier GCC versions. This is due to stricter standard conformance of the compiler and can be avoided by using the option -fexcess-precision=fast.

4.4.2. Optimizer improvements

  • The -save-temps now takes an optional argument. The -save-temps and -save-temps=cwd switches write the temporary files in the current working directory based on the original source file. The -save-temps=obj switch will write files into the directory specified with the -o option, and the intermediate filenames are based on the output file.
  • Debugging dumps are now created in the same directory as the object file rather than in the current working directory.
  • A new link-time optimizer has been added (-flto). When this option is used, GCC generates a bytecode representation of each input file and writes it to special ELF sections in each object file.
  • The automatic parallelization pass was enhanced to support parallelization of outer loops.
  • GCC now optimize exception handling code.
Reference the changes page above for more details on these and other optimizations.

5.4. Musicians

5.4.1. jack2

Fedora 14 moves from jack to jack2, formerly called jackdmp. jack2 offers many improvements over previous versions available in Fedora. Current jack-capable programs can take advantage of these improvements without modification.
  • jack2 takes advantage of multi-processor and multi-core systems. The result is fewer audio glitches when more than one jack-enabled program is run.
  • You can now modify connections without interrupting the audio stream. This means that you do not need to stop recording or playback in order to change how your programs connect to each other.
  • "Asynchronous" activation prevents audible audio glitches. If a program does not provide a sample in time, jack2 automatically repeats the previous sample. The old jack server would have produced an audible glitch, but with jack2, you may not even hear the missing sample.
  • You can use jack2 and PulseAudio on the same computer. When the jack server starts, it automatically takes control of your audio hardware from PulseAudio. When the jack server stops, it automatically returns control of your audio hardware to PulseAudio. There is no longer a benefit to removing PulseAudio.
The move to jack2 is another example of the behind-the-scenes improvements that are a part of Fedora 14.

5.4.2. Musicians' Guide

Created as a Fedora Summer Coding project, the Fedora Musicians' Guide is released for the first time with Fedora 14. The Musicians' Guide shows you how to use several popular audio and music applications available in Fedora, and it explains some basic concepts you need to know when using audio software on any computer.
Each application has a tutorial, designed to show a typical use of the application by creating an actual musical project. In the Ardour tutorial, for example, you learn how to mix and master a recording of a real song. In the Qtractor tutorial, you learn how to create a MIDI-based accompaniment for a recording of a Beethoven piano sonata.
More advanced users - especially programmers who wish to create music - will appreciate the detailed coverage of SuperCollider, a programming language designed for audio synthesis. The tutorial shows you how to create a piece of music, from inspiration to completion. There is also a section explaining the syntax and usage of many language features, designed to be used as an introduction to SuperCollider, and as a reference while you program. Combined with the extensive documentation available from the developers, the Musicians' Guide chapter help to make SuperCollider on Fedora easier than ever!
All musicians who want to improve their skills will want to use the ear-training application Solfege. Solfege offers a wide variety of exercises, from hearing and singing intervals and chords, to taking dictation of a series of chords, or even detecting a tuning discrepancy between pitches. Whether you want to build your aural skills for the first time or just want help in maintaining them, Solfege can help you.
The Musicians' Guide is available from the Docs Project Website, located at

5.4.3. Qsynth

Qsynth is a graphical front-end for the FluidSynth software-based MIDI synthesizer. Qsynth lets you take advantage of the full capabilities of FluidSynth more easily. You can change all aspects of a FluidSynth setup, and even run multiple instances of the FluidSynth synthesizer, from within one Qsynth window.
Qsynth is explained in Chapter 10, "FluidSynth" of the new Musicians' Guide (
