1. Welcome to Fedora 19

1.1. Welcome to Fedora

You can help the Fedora Project community continue to improve Fedora if you file bug reports and enhancement requests. Refer to Bugs And Feature Requests, on the Fedora wiki, for more information about bug and feature reporting. Thank you for your participation.
To find out more general information about Fedora, refer to the following pages, on the Fedora wiki (http://fedoraproject.org/wiki/):

1.1.1. Need Help?

There are a number of places you can get assistance should you run into problems.
If you run into a problem and would like some assistance, go to http://ask.fedoraproject.org. Many answers are already there, but if you don't find yours, you can simply post a new question. This has the advantage that anyone else with the same problem can find the answer, too.
You may also find assistance on the #fedora channel on the IRC net irc.freenode.net. Keep in mind that the channel is populated by volunteers wanting to help, but folks knowledgeable about a specific topic might not always be available.

1.2. Overview

As always, Fedora continues to develop (Red Hat contributions) and integrate the latest free and open source software (Fedora 19 Features). The following sections provide a brief overview of major changes from the last release of Fedora.
For more details about the features that are included in Fedora 19 refer to the individual wiki pages that detail feature goals and progress: http://fedoraproject.org/wiki/Releases/19/FeatureList.

1.3. Hardware Overview

Fedora 19 provides software to suit a wide variety of applications. The storage, memory and processing requirements vary depending on usage. For example, a high traffic database server requires much more memory and storage than a business desktop, which in turn has higher requirements than a single-purpose virtual machine.

1.3.1. Minimum System Configuration

The figures below are a recommended minimum for the default installation. Your requirements may differ, and most applications will benefit from more than the minimum resources.
1GHz or faster processor
1GB System Memory
10GB unallocated drive space

Low memory installations

Fedora 19 can be installed and used on systems with limited resources for some applications. Text, vnc, or kickstart installations are advised over graphical installation for systems with very low memory. Larger package sets require more memory during installation, so users with less than 768MB of system memory may have better results preforming a minimal install and adding to it afterward.
For best results on systems with less than 1GB of memory, use the DVD installation image.

1.3.2. Graphics Hardware

1.3.2.1. Minimum Hardware for Accelerated Desktops
Fedora 19 supports most display adapters. Modern, feature-rich desktop environments like GNOME3 and KDE Plasma Workspaces use video devices to provide 3D-accelerated desktops. Older graphics hardware may not support acceleration:
Intel prior to GMA9xx
NVIDIA prior to NV30 (GeForce FX5xxx series)
Radeon prior to R300 (Radeon 9500)
1.3.2.2. CPU Accelerated Graphics
Systems with older or no graphics acceleration devices can have accelerated desktop environments using LLVMpipe technology, which uses the CPU to render graphics. LLVMpipe requires a processor with SSE2 extensions. The extensions supported by your processor are listed in the flags: section of /proc/cpuinfo
1.3.2.3. Choosing a Desktop Environment for your hardware
Fedora 19's default desktop environment, GNOME3, functions best with hardware acceleration. Alternative desktops are recommended for users with older graphics hardware or those seeing insufficient performance with LLVMpipe.
Desktop environments can be added to an existing installation and selected at login. To list the available desktops, use the yum grouplist command:
        yum grouplist -v hidden | grep desktop
Install the desired group:
        yum groupinstall "KDE Plasma Workspaces"
Or, use the short group name to install:
        yum install @mate-desktop-environment

1.4. Feedback

Thank you for taking the time to provide your comments, suggestions, and bug reports to the Fedora community; this helps improve the state of Fedora, Linux, and free software worldwide.

1.4.1. Providing Feedback on Fedora Software

To provide feedback on Fedora software or other system elements, please refer to Bugs And Feature Requests. A list of commonly reported bugs and known issues for this release is available from Common F19 bugs, on the wiki.

1.4.2. Providing Feedback on Release Notes

2. Changes in Fedora for System Administrators

2.1. Kernel

Fedora 19 features the 3.9.0 kernel.

2.2. Installation

2.2.1. Minimum Screen Resolution

Graphical Installation requires 800x600 resolution or higher

Graphical installation of Fedora 19 requires a minimum screen resolution of 800x600. Owners of devices with lower resolution, such as some netbooks, should use text or VNC installation.
Once installed, Fedora will support these lower resolution devices. The minimum resolution requirement applies only to graphical installation.

2.2.2. Syslinux

Fedora 19 includes an option for using the Extlinux bootloader, part of the Syslinux family of bootloaders. This bootloader is not as advanced as the default Grub2 bootloader and will not work in all circumstances. The target use-case for F19 is lightweight cloud images, but you may find Extlinux useful in other situations as well.
Currently, Extlinux does not support LVM, and while it does support btrfs, that support is limited. An ext2, ext3, or ext4 boot filesystem is required, as either the root filesystem or a small standalone /boot partition. Additionally, currently only X86 architectures are supported.
To enable Extlinux, either use the extlinux keyword on the Anaconda command line, or use the "--extlinux" flag for the bootloader command in kickstart. This feature is not made visible in the installer's graphical or text-mode user interfaces.

Syslinux is not preferable to grub for most end users!

This support is currently targeted at a narrow use case, primarily virtual machines, and Extlinux will not work for all situations in Fedora 19.

2.2.3. Firstboot configuration

Initial setup screens have been revamped for Fedora 19. GNOME now offers user creation and configuration at first boot. Other environments will instead use the new functionality from the installer.

2.2.4. Remote Authentication support is limited

The Fedora 19 installer does not currently support configuration of remote authentication during installation. However, if GNOME is being installed and no users are created by the installer, the first boot of GNOME will provide a user creation dialog that supports FreeIPA and AD.
Users requiring remote authentication under other use cases should configure it in a kickstart file or after the installation is complete.

2.2.5. Advanced Storage

The rewrite of the anaconda installer begun in Fedora 18 continues. Fedora 19 provides support during installation for advanced storage, such as fcoe, iscsi, and multipath. The text mode of the installer has also been improved.

2.2.6. AD domain integration

Fedora can now join a domain from a kickstart file or from the anaconda, using one time passwords and a simple syntax.
        # example kickstart lines to join realm:
        network --hostname=machine.ad.example.com
        realm join --one-time-password=MyPassword ad.example.com

2.3. Boot

2.3.1. Faster Boot with host only initramfs.

Rescue and Rebuild for major changes

Boot speed is improved by removing unused features from the initramfs. If new hardware is added, boot into the rescue initramfs and use the command dracut --regenerate-all --force to rebuild and replace the old initramfs.
This Fedora release builds an initramfs tailored especially for your computer hardware, allowing faster boot. If you change your machine or significant hardware, you might have to boot with the Rescue boot entry and execute dracut --regenerate-all. If you want your initramfs to be hardware independent, install the dracut-nohostonly rpm package. If you don't want rescue images at all (like in virtual machines), install the dracut-norescue rpm package.

2.3.2. Visual Changes to GRUB

The appearance of GRUB and GRUB menus have been changed to present a more seamless, appealing look.

2.4. Security

2.4.1. Hardlink and symlink restrictions

A long-standing class of security issues is the link based time-of-check-time-of-use race, most commonly seen in world writable directories like /tmp. The common method of exploitation of this flaw is to cross privilege boundaries when following a given link, such as when a root process follows a link belonging to another user. In Fedora 19, we permit links to only be followed when outside a sticky world-writable directory, or when the uid of the link and follower match, or when the directory owner matches the link's owner. In previous releases, this was enforced by SELinux policy and in this release, the restrictions are enabled by sysctl settings in /usr/lib/sysctl.d/00-system.conf as an additional layer of protection:
        fs.protected_hardlinks = 1
        fs.protected_symlinks = 1

2.4.2. Shared System Certificates

Root anchored certificate authorities are consumed from single location and shared by most applications, unless those applications are explicitly configured with other certificates.
A system administrator can now place a non-standard certificate authority to be a trusted root as a file in a directory location. After running a tool, it will be used by most applications as expected, except those otherwise configured.

2.4.3. FreeIPA

2.4.3.1. FreeIPA realmd support
It is now possible to simply configure a client to use a FreeIPA domain for authentication by using the GNOME Control Center, kickstart or command line:
          realm join myipadomain.com
2.4.3.2. FreeIPA Trust Improvements
When using FreeIPA to trust Active Directory domain, it is now possible to designate multiple domain controllers in FreeIPA to server Windows clients.
FreeIPA has added management of additional domain suffixes visible to the trusted Active Directory domain's clients.
FreeIPA now implements Global Catalog service to allow Active Directory domain administrators to FreeIPA users.

2.4.4. SSSD improves AD integration

With the latest major release to SSSD the integration into Active Directory domains has been improved. AD sites are respected and SSSD tries to access the nearest domain controller. Users and groups from trusted domains are available.

2.4.5. More resilient Kerberos

Kerberos in Fedora 19 has been improved. It is now possible to authenticate using kerberos regardless of the local system time being in sync with that of the kerberos server.
Various kerberos bugs, including handling of reverse DNS records, have been fixed in order to make a more seamless kerberos experience.

2.4.6. gssproxy

Fedora 19 features gssproxy, an opensource project that aims to improve GSSAPI usage from both the kernel for authenticating remote file system access as well as user-space applications. It does provide fine-grained access control on Kerberos keytab access and it overcomes various limitations the kernel had when dealing with Kerberos tickets.

2.5. Virtualization

2.5.1. open-vm-tools

open-vm-tools, the open source implementation of VMware Tools, is now available from Fedora.

2.5.2. High Availability container resources

Pacemaker now supports the ability to manage resources remotely on non-cluster nodes through the use of the pacemaker_remote service. This feature allows pacemaker to manage both virtual guests and the resources that live within the guests all from the host cluster node without requiring the guest nodes to run the cluster stack.

2.5.3. Virt Storage Migration

KVM and libvirt now support a performant way to live migrate virtual machines with no shared storage between the hosts. A running VM and its disk images are relocated to a new machine with no downtime.

2.6. Web Servers

2.7. Cloud

2.7.1. Ready-to-run cloud images

Ready-to-run cloud images are provided as part of Fedora 19. These are available in Amazon EC2 or for direct download. The downloadable images are available in compressed raw image format and in qcow2 for immediate use with EC2, OpenStack, CloudStack, or Eucalyptus. The images are configured with cloud-init, and so will take advantage of ec2-compatible metadata services for provisioning SSH keys.

2.7.2. OpenShift Origin

OpenShift Origin, the community-supported version of Red Hat's OpenShift, is available for the first time in Fedora 19.

2.7.3. OpenStack Grizzly

OpenStack is upgraded to the latest stable release, code named "Grizzly". OpenStack Grizzly includes the Incubation projects Heat and Ceilometer, as well as numerous other upgrades and improvements. A detailed list of changes is available at https://wiki.openstack.org/wiki/ReleaseNotes/Grizzly

2.8. Database Servers

2.8.1. MariaDB

Fedora 19 features MariaDB, an improved and more open fork of MySQL with a thriving community. MariaDB is used as the default mysql compatible database, and the change should be transparent to almost all MySQL users. If required, the original MySQL packages are still available as community-mysql.

2.8.2. Derby

Apache Derby, an open source relational database implemented entirely in Java, has been updated to version 10.9.1.0. For detailed information on the changes to Derby, consult the project's website at http://db.apache.org/derby/

2.8.3. sqlite

The functionality of sqlite has been expanded and improved with the update to version 3.7.15. The project provides a release history at http://www.sqlite.org/changes.html

2.9. File Servers

2.9.1. NFSTest

Fedora 19 offers NFSTest, a suite of tools for testing NFS clients and services. Detailed information is available at http://wiki.linux-nfs.org/wiki/index.php/NFStest

2.10. System Daemons

2.10.1. Private Temporary Directories available

Services with a PrivateTmp= directory defined in their configuration make use of a private temporary directory that is shared by all processes of the service. These temporary files are deleted when the service is stopped.

2.10.2. systemd

2.10.2.1. Modular service configuration with drop-in files
systemd will now look for configuration directives for a service as /etc/systemd/system/foo.service.d/bar.conf, making site-specific changes easier to organize and deploy.
2.10.2.2. systemd lightweight containers
nspawn containers have been improved in order to allow installation an unmodified Fedora distribution for testing, debugging, and development.
2.10.2.3. systemd Message Catalog
The systemd Message Catalog uses globally-unique message identifiers to tie specific error messages to additional information such as comprehensive explanations and links to further information.
2.10.2.4. systemd Resource Control
In Fedora 19, systemd adds the ability to dynamically modify cgroups-based resource control for services.
2.10.2.5. systemd timers
systemd adds support for calendar time events, in addition to existing support for monotonic time events.
2.10.2.6. systemd-analyze
systemd-analyze can now use the GraphViz dot tool to generate graphs of the boot process. GraphViz can be installed with yum install graphviz and will create a representation of the full boot process with systemd-analyze dot | dot -Tsvg > systemd.svg More refined plots can be generated with the optional arguments --order, --require, --from-pattern=, and --to-pattern=
For more details and examples, refer to man 1 systemd-analyze.
2.10.2.7. Socket tools
systemd now provides some tools for working with socket units:
systemctl list-sockets to show the sockets systemd is listening on, the socket units they belong to, and the units they activate.
systemd-activate to test socket activation.
2.10.2.8. Changes in the journal
Journal files are now owned by the dedicated "systemd-journal" group instead of the 'adm' group.
Changes to journalctl usage include:
journalctl -r to see newest entries first.
journalctl -e to skip to the end of the list.
journalctl --user-unit="foo" to filter by user units
A new module in the systemd python API for reading the journal
journalctl now persistently stores journal log data in /var/log/journal. In previous releases, journal data was stored in /var/run/journal, which is volatile and cleared on reboot. Starting with Fedora 19, journal data persists between reboots.

2.11. Server Configuration Tools

2.11.1. yum-presto merged into yum

The yum-presto plugin, used for handling delta RPM files, has been merged into yum. To disable use of delta RPM packages, set deltarpm=0 in /etc/yum.conf. Refer to man yum.conf for more details.

2.11.2. Yum-enabled LVM snapshots

By using the yum-plugin-fs-snapshot package, thinly provisioned LVM filesystems can be automatically snapshot on package updates.
Existing thinly provisioned volumes are required. Snapshotting is enabled in the plugin's configuration file at /etc/yum/pluginconf.d/fs-snapshot.conf:
Set enabled=1 in the [lvm] section to enable.
set create_snapshots_in_post=1 in the [main] section to create a snapshot after the yum transaction.

2.11.3. Yum groups as objects

By handling package groups as objects rather than static lists, package managers like yum will now store the information and use it for later group related commands, and updates will automatically bring in new packages added to the group.

2.11.4. Easier Administration with OpenLMI

The OpenLMI infrastructure has been greatly improved. A new storage API and providers for monitoring, hardware information, realmd, and firewall have been added. Improvements have also been made in in the existing providers. Packaged documentation has been updated to reflect the new features.

2.12. Monitoring and Management Solutions

2.12.1. Performance Co-Pilot

Performance Co-Pilot, a framework and suite of servers for system-level performance monitoring and management, has been updated to version 3.7. Consult the project's release notes at http://oss.sgi.com/projects/pcp/news.html and their documentation at http://oss.sgi.com/projects/pcp/pcp-gui.git/man/html/index.html

2.12.2. Puppet

Fedora 19 ships the 3.x series of the popular puppet toolkit. For details on puppet 3, consult the project's documentation at http://docs.puppetlabs.com/puppet/3/reference/release_notes.html

3. Changes in Fedora for Desktop Users

3.1. Desktop

3.1.1. Cinnamon

The latest release of the popular desktop environment Cinnamon brings new features and polish to Fedora 19:
nemo, the file manager, has been heavily modified to integrate its behavior with Cinnamon.
screensaver has been improved, including a lock screen with customizable away message.
control center is more comprehensive.
desklets are desktop applets, and the Cinnamon community offers a variety of them.
spices are Cinnamon customizations, such as desklets, applets, themes, and extensions. They can now be installed with a desktop utility.
While originally based on GNOME, Cinnamon is maturing into an independent, fully featured fork. For news and details about the Cinnamon project, visit http://cinnamon.linuxmint.com

3.1.2. GNOME

Fedora 19 includes the latest version of the GNOME desktop, 3.8. For more information about what is new in this GNOME release, visit the project's release notes at http://library.gnome.org/misc/release-notes/3.8
3.1.2.1. Session logs moved into journal
User session logs, previously stored in $HOME/.cache/gdm/session.log, have moved into the journal.
To view your user session log, identify your user ID and view the journal for that UID :
	  $ id
	  uid=1000(username) gid=1000(username) groups=1000(username) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
	  $ journalctl _UID=1000
3.1.2.2. Support for extracting RAR files
File Roller, the graphical archive manager for GNOME, can support extraction of files from RAR archives after installation of the unar package. unar is a free and open source command line multi-format extractor that is part of The Unarchiver project for extracting RAR files, including encrypted and multi-volume archives. In previous Fedora releases, users have had to install the non-free unrar tool from a third party repository for the same purpose. This is not necessary anymore.
Fedora still does not have any default support for creating new RAR files since there is no free and open source tool that provides this functionality. Fedora however includes support for several free and open source compression formats that are generally considered to be more efficient than RAR, such as the popular XZ format and it is recommended that you use it to distribute compressed files.

3.1.3. KDE

Fedora 19 features KDE Plasma Workspaces version 4.10 and the newest version of KDE Platform and Applications. To learn more about the release, consult http://www.kde.org/announcements/4.10/
3.1.3.1. KScreen
Configuration of multiple displays is improved with KScreen, a new screen management software for KDE. It has a new UI for monitors configuration and automatic saving and restoring of profiles for connected monitors.

3.1.4. MATE

The latest version of a familiar favorite, MATE 1.6 builds on modern functionality to provide a polished, stable desktop environment.
Read more about changes in MATE from the project's release announcement at http://mate-desktop.org/2013/04/02/mate-1-6-released/

3.2. Productivity

3.2.1. LibreOffice 4.0

LibreOffice has been updated to version 4.0, with many notable features and fixes. For detailed information on these changes, read http://www.libreoffice.org/download/4-0-new-features-and-fixes/

3.2.2. Command line tools

findutils has been updated to version 4.5.11, bringing several functional changes. Users of find should consult /usr/share/doc/findutils-*/NEWS for changes, including xargs, printf and regex functions.
sed gains the new command F to print the input file names, a new option -z or --null-data to separate lines by ASCII NULL characters, and other fixes described in /usr/share/doc/sed-*/NEWS

3.3. Networking

3.3.1. Federated VoIP

Fedora 19 offers better support for truly federated VoIP, with the reSIProcate (repro) SIP proxy and reTurnServer, an ICE, STUN, and TURN server for both SIP and XMPP (Jabber) networks.

3.3.2. Improved Mobile Broadband support

Fedora 19 includes a new, more capable version of ModemManager for interacting with mobile broadband devices. This version provides better support for multi-mode devices like Qualcomm Gobi WWAN cards and other devices that support the CDMA/EVDO/LTE standards, the GSM/UMTS/LTE standards, or devices that can support either. To provide this support, the D-Bus API of ModemManager has changed, which may require updates in applications that interact with ModemManager to control WWAN devices.
Many devices will connect and authenticate using the NetworkManager GUI. nm-cli has added features to configure mobile connections. For more detailed usage information, consult http://fedoraproject.org/wiki/Features/MoreMobileBroadband .

3.3.3. firewalld improvements

The firewall daemon, firewalld, introduced as the default firewall solution in Fedora 18, adds new features to allow easy configuration of this powerful firewall.
3.3.3.1. Locking the firewall and whitelisting changes
Dynamic firewall configuration by applications can now be locked down completely, or limited to a whitelist. The whitelist can contain commands, users, UIDs, and SELinux contexts.
To lock down the firewall, set Lockdown=yes in /etc/firewalld/firewalld.conf and reload the firewall.
          firewall-cmd --reload
The firewall should be reloaded for any changes to the whitelist to take effect.
The whitelist configuration is located in /etc/firewalld/lockdown-whitelist.xml and is empty by default. The whitelist below will allow only firewall-cmd to make changes to the firewall. The '*' character allows the rule to match arguments passed to firewall-cmd
        
<whitelist>
  <command name="/usr/bin/python /bin/firewall-cmd*" />
</whitelist>

For more information on firewalld lockdown, consult the feature page at http://fedoraproject.org/wiki/Features/FirewalldLockdown
3.3.3.2. Rich Language for rule configuration
Fedora 19 includes the latest firewalld version, which supports a rich language to be able to create more complex firewalls in a easy way. To take advantage of the new system, read http://fedoraproject.org/wiki/Features/FirewalldRichLanguage

3.3.4. OpenVPN 2.3

OpenVPN has been updated to version 2.3, bringing numerous feature enhancements, bugfixes, and expanded documentation. For detailed information on these changes, consult https://community.openvpn.net/openvpn/wiki/ChangesInOpenvpn23

3.3.5. OpenConnect

OpenConnect has been updated to version 4.99, adding XML POST support for solutions such as AnyConnect, the --os switch to report a different OS type to the gateway, and SecurID token support using libstoken.

3.3.6. BIND10

The BIND10 suite is now shipped in the Fedora repositories. This includes the DNS server daemon named, the dhcpd server daemon, and related utilities. Documentation is available at http://bind10.isc.org/wiki and the BIND10 Guide.
Starting with Fedora 19, the named PID file has been moved from /var/run/named/named.pid to /run/named/named.pid. Users with a custom named.conf migrating to Fedora 19 should add a pid-file statement to the options section:

options {
        ...
        pid-file      "/run/named/named.pid";
        ...
        };

3.3.7. Stable network interface naming

The udevd service has a long history of providing predictable names for block devices and others. Fedora will now also use udev naming for network interfaces by default, providing more reliable interface names on systems with multiple network devices. Alternative naming schemes, such as custom udev rules or biosdevname, will override this default. Users upgrading from previous releases may need to update the device names referenced in /etc/system/network-scripts/, although in most cases biosdevname will continue to manage naming.

3.4. Internationalization

3.4.1. Input Methods

  • ibus
    Default keybinding to turn Input Method on and off has been changed to Super+space

4. Changes in Fedora for Developers

4.1. Development

4.1.1. Scratch

Fedora 19 includes Scratch, the graphical programming environment from the Lifelong Kindergarten Group at the IT Media Lab. Scratch makes it easy to create your own interactive stories, games, animations, music, and art.
Install Scratch with
        yum install scratch
and run either from your desktop's application menu (under Programming) or by typing `scratch` in a terminal window.

4.1.2. New Ruby 2.0.0

Ruby is available in Fedora 19. The new release provides additions to the core language, new built-in libraries, improved debug support, and performance enhancements.
The Ruby project has given detailed changes and compatibility guidelines, in the release announcement available at http://www.ruby-lang.org/en/news/2013/02/24/ruby-2-0-0-p0-is-released/

4.1.3. JRuby 1.7

JRuby has been updated to version 1.7 and featuring improved packaging. Details on the release are available at http://jruby.org/2012/10/22/jruby-1-7-0.html

4.1.4. Erlang

The general purpose concurrent programming language and runtime Erlang has been updated to R16B. The full changelog is available at http://www.erlang.org/download/otp_src_R16A_RELEASE_CANDIDATE.readme and http://www.erlang.org/download/otp_src_R16B.readme. Documentation includes http://vimeo.com/44790646 and http://www.erlang.org/download_release/17

4.1.5. Boost Updated to 1.53

Fedora 19 includes Boost version 1.53. Compared to 1.50 shipped with Fedora 18, Boost 1.53 comes with several new libraries:
Context, for context switching
Coroutine, a coroutine library
Lockfree, lockfree data structures
Multiprecision, extended precision arithmetic types for floating point, integer and rational arithmetic
Atomic, C++11-style atomic<>
Odeint, for solving ordinary differential equations
Many other libraries were updated. The detailed release notes are available for Boost 1.51.0, 1.52.0 and 1.53.0:
Boost 1.50.0 Release Notes
Boost 1.51.0 Release Notes:
Boost 1.52.0 Release Notes:
Boost 1.53.0 Release Notes

Backwards Compatibility

Note that neither API, nor ABI compatibility with Boost 1.50 may be assumed. Third party applications built against older versions of Boost will need to be recompiled, and may need to be patched to work well with Boost 1.53.

4.1.6. GNU Guile updated to version 2.0.7

GNU Guile has been updated to version 2.0.7 . Third party applications that depend on legacy guile can use the compat-guile18 package. More information about Guile 2 can be found at http://www.gnu.org/software/guile/download.html#releases

4.1.7. Python

4.1.7.1. Pillow replaces PIL
The Python Imaging Library, or PIL, has been replaced with Pillow, an actively maintained fork, which also offers Python 3 compatible modules. Pillow is a drop-in replacement for PIL, except that importing modules now requires
          from PIL import <Module>
syntax instead of simply
          import <Module>
This change does not break backwards compatibility with the legacy PIL. Documentation is available at https://github.com/python-imaging/Pillow/
4.1.7.2. PyXML removed, use stdlib
Python programmers who use the xml module may find that a few pieces of it work differently than in the past. This is due to Fedora no longer shipping PyXML. This change allows the python stdlib xml module to be visible to programmers. PyXML had replaced the stdlib code with its own less maintained code, and dropping PyXML ensures that the stdlib functions are preferred.

4.2. Development Tools

4.2.1. Checkpoint and restore with crtools

The CRIU (Checkpoint/Restore in User-space) project offers a user-space implementation of process and process group checkpoint/restore. With the user-space tools crtools available in this release it is possible to checkpoint processes and restore them at a later time again (e.g. after a crash) or migrate the checkpointed process or process group to another system. CRIU aims to be as transparent as possible so that no instrumentation or re-compilation of the process to be checkpointed is necessary.
To dump a process, use the command:
        crtools dump -D /path/to/dump-directory -t <PID>
To restore a process, use the command:
        crtools restore -D /path/to/dump-directory -t <PID>
The CRIU project can be found at http://criu.org

4.2.2. Developer's Assistant

New developers get a quick start with Developer's Assistant, a set of tools for rapidly starting projects with a variety of languages and frameworks. The devassistant package currently supports:
C and C++
python including django and flask
java including jsf and maven

4.2.3. MEMSTOMP

Fedora 19 offers MEMSTOMP, a DSO which can be preloaded into an application to discover overlapping memory arguments to certain functions at a lower runtime cost than valgrind.

4.2.4. New Tools

recode adds the ability to convert files between character sets and usages
comdemod is a tool to assist with large scale code base refactors.
jimtcl, a lightweight Tcl implementation.
fox, a C++ based toolkit for developing graphical user interfaces easily and effectively.

4.3. GCC Tools

4.3.1. GCC 4.8.x

As of Fedora 19, GCC 4.8.x is shipped as the default GCC. In addition, all Fedora packages have been rebuilt with GCC 4.8.x (and GLIBC 2.17; see below)
Users will be able to examine compiled code improvements and use the newly added features, such as improved C++11 and C11 support, improved vectorization support, etc.
Updates to GCC include the MinGW cross-compiler. One of the most notable changes is that the default exception handling model for the win64 target was changed from SjLj to SEH. The win32 target still uses the SjLj exception handling model. This causes all binaries for the win64 target which use exception handling to depend on libgcc_s_seh-1.dll instead of libgcc_s_sjlj-1.dll.
For more information on the changes in GCC 4.8.x, please visit http://gcc.gnu.org/gcc-4.8/changes.html

4.3.2. GLIBC 2.17

As of Fedora 19, GLIBC 2.17 is shipped as the default GLIBC. All Fedora packages have been rebuilt with GLIBC 2.17 (and GCC 4.8.x; see above).
For more information on the changes in GLIBC 2.17, please refer to http://sourceware.org/ml/libc-announce/2012/msg00001.html

5.1.9. Octave

octave has been updated to 3.6.4.

5.1.10. qcad

qcad has been dropped from Fedora.

5.1.11. R

R is a language and environment for statistical computing and graphics. Fedora 19 includes the latest 3.0.0 release of R, which is a major upgrade.

Must re-install packages

There are many add-on packages for R which must be re-installed for this release.
A major thrust of release 3.0.0 is to better exploit 64-bit platforms, however there are many, many improvements to a number of functions. Perhaps obviously, support for long vectors has been greatly improved, but there are dozens of improvements to other functions as well.
For full details on this new release of R, the reader is referred to the NEWS page at http://cran.r-project.org/src/base/NEWS.html.
In addition to updates to R itself, a number of R packages have also been enhanced. The table below lists those packages and the upstream web sites to obtain additional information:

5.1.12. Veusz

veusz has been updated to 1.17.1. Some new features include:
  • Allow coloured points for non-orthogonal plots (polar, ternary)
  • Remove unnecessary exception data
  • Add new broken axis widget with gaps in the numerical sequence
  • Grid lines are plotted always under (or over) the data
  • Shift+Scroll wheel scrolls left/right
  • Polar plots can have a "minimum" radius and log axes
  • Many more LaTeX symbols added
  • Add SAMP/VoTable support
  • New shifted-points xy line mode, which plots a stepped line with the points shifted to lie between the coordinates given
  • Points can be picked to console and/or clipboard
  • Allow reversed ternary plot

5.1.13. Sailcut

Fedora 19 adds sailcut, CAD software for designing and visualizing sails.

5.2. Circuit Design

5.2.1. gtkwave

gtkwave has been updated from 3.3.41 to 3.3.46.

5.2.2. XCircuit

xcircuit has been updated to 3.7.44. Version 3.7 has a modified selection mechanism that considers both points and segments of elements as well as entire elements. This allows the "edit" function to work as a stretch function to many elements at once.
Also added linewidth invariance on objects. Object instances (such as circuit symbols) can be made linewidth-invariant, such that an instance of the object can be scaled without changing the linewidth. This allows some circuit symbols to be resized relative to others on the same schematic without a discontinuity in wire width at the pins.
A number of other useful additions including:
  • Tracking spline control points for adjoining splines in paths
  • Clipmasks (shapes can be used to clip the view of other elements)
  • polygon-to-curve conversion routine
  • undo/redo on raise/lower elements
  • single-step raise and lower elements
  • gradient field generator---color graded fields are made from graphic image types

5.3. Embedded Development

5.3.1. avr-gcc

avr-gcc and avr-gcc-c++ have been updated to 4.7.3. Changes include:
  • The -fconserve-space flag has been deprecated. The flag had no effect for most targets: only targets without a global .bss section and without support for switchable sections. Furthermore, the flag only had an effect for G++, where it could result in wrong semantics (please refer to the GCC manual for further details). The flag will be removed in GCC 4.8
  • The AVR port's libgcc has been improved and its multilib structure has been enhanced. As a result, all objects contributing to an application must either be compiled with GCC versions up to 4.6.x or with GCC versions 4.7.1 or later. If the compiler is used with AVR Libc, you need a version that supports the new layout, i.e. implements #35407.
  • The AVR port's -mshort-calls command-line option has been deprecated. It will be removed in the GCC 4.8 release. See -mrelax for a replacement.
  • The AVR port only references startup code that clears .bss and the common section resp. initializes the .data and .rodata section provided respective sections (or subsections thereof) are not empty, see PR18145. Applications that put all static storage objects into non-standard sections or define all static storage objects in assembler modules, must reference __do_clear_bss resp. __do_copy_data by hand or undefine the symbol(s) by means of -Wl,-u,__do_clear_bss resp. -Wl,-u,__do_copy_data.
  • GCC versions 4.7.0 and 4.7.1 had changes to the C++ standard library which affected the ABI in C++11 mode: a data member was added to std::list changing its size and altering the definitions of some member functions, and std::pair's move constructor was non-trivial which altered the calling convention for functions with std::pair arguments or return types. The ABI incompatibilities have been fixed for GCC version 4.7.2 but as a result C++11 code compiled with GCC 4.7.0 or 4.7.1 may be incompatible with C++11 code compiled with different GCC versions and with C++98/C++03 code compiled with any version.
In addition, there are a number of improvements to the optimizer. The reader is referred to http://gcc.gnu.org/gcc-4.7/changes.html for additional details.

5.3.2. gputils

gputils has been upgraded to version 1.1.0 from 0.14.3. Changes in 1.1.0 include:
  • added -P (--preprocess) command line option to emit preprocessed asm file
  • added support for undocumented HALT, TRAP and TRET opcodes
  • .inc and .lkr files are synced with MPLABX 1.70
  • fixed support for 12 bit extended instruction set, devices PIC12F529T48A, PIC12F529T39A, PIC16F527 and PIC16F570

5.3.3. z88dk

z88dk has been upgraded from 1.10 to 1.10.1. This slightly modified release includes a bugfix in CPP preventing the inline assembler to work correctly plus few minor target specific corrections (ZX81 and MTX among the others)

5.4. Amateur Radio

5.4.1. chirp

chirp has been upgraded to 0.3.0. Some new features:
  • Automatic split->offset conversion during import when odd-split is not supported

demorse has been updated to 1.1. This is primarily a maintenance release and no changes should be user visible.

5.4.3. fldigi

fldigi 3.21.68 is now included in Fedora 19. This is primarily a maintenance/bugfix release.

5.4.4. gnuradio

There are quite a number of changes to get gnuradio to version 3.6.4.1, including:
  • Addition of the ability to add and connect formally defined asynchronous message ports to signal processing blocks and hierarchical blocks
  • the concept of PDUs (Protocol Data Units) as a convention for passing data+metadata using the new messaging ports
  • A few new general purpose blocks supporting these capabilities are in gnuradio-core:
    • gr_message_debug
    • gr_message_strobe
    • gr_tagged_stream_to_pdu
    • gr_pdu_to_tagged_stream
  • Two new blocks for interfacing with networking stacks using the new PDU semantics:
    • gr_socket_pdu
    • gr_tuntap_pdu
  • Addition of new Python-based signal processing blocks
  • Addition of gr-analog top-level component
  • Addition of gr-blocks top-level component
  • Metadata file source and sink blocks
  • GNU Radio buffer latency control
  • Ability to set processor affinity for GNU Radio blocks
  • Inclusion of gr_modtool
  • Use of GNU Radio preferences in native C++ applications
  • Addition of GNU Radio block performance counters
  • dozens of other features considered minor

5.4.5. linsmith

Fedora 19 includes version 0.99.24 of linsmith. Improvements include:
  • Slight improvements to the vector plot.
  • Better default values for colors of plot.
  • Modified the confmgr to accept hex and octal values in the configuration file.
  • Removed the (deprecated) gnomeprint dependency. Now the complete print route relies on Pango/Cairo to generate the plot, and the GtkPrint interface to do the actual printing.
  • Change papersize_combo to combobox, and load the list from the available papersizes.
  • Adapted confmgr to accept char * from comboboxes.
  • Moving elements up implemented.
  • Converted the strange negative default values for the color definitions to their (easier to understand?) hex values.
  • The 'standard cable' code mostly re-written, and a few more cable types added.

5.4.6. soundmodem

soundmodem has been updated to 0.16, primarily to interoperate with systemd.

5.4.7. xnec2c

xnec2c 2.1 includes a number of improvements:
  • Modify the xnec2c user interface so that it will, as far as possible, allow the user to save and re-open NEC2 files in the Editor window, without closing the Radiation Pattern and/or the Frequency Plots windows
  • replaced all the (deprecated) GDK drawing primitives with equivalent Cairo graphics equivalents (e.g. replaced gdk_draw_line() with cairo_line_to()) since Cairo provides for nicer anti-aliased drawing.
  • added code to save data of the structure display, radiation patterns and frequency plots into file, in a format suitable for the "gnuplot" plotting program
