SSE2 extensions. The extensions supported by your processor are listed in the flags: section of /proc/cpuinfo
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

Graphical Installation requires 800x600 resolution or higher
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!
fcoe, iscsi, and multipath. The text mode of the installer has also been improved.
# example kickstart lines to join realm:
network --hostname=machine.ad.example.com
realm join --one-time-password=MyPassword ad.example.com
Rescue and Rebuild for major changes
dracut --regenerate-all --force to rebuild and replace the old initramfs.
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.
/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

Global Catalog service to allow Active Directory domain administrators to FreeIPA users.
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.
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.

/etc/systemd/system/foo.service.d/bar.conf, making site-specific changes easier to organize and deploy.
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=
man 1 systemd-analyze.
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. |
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.
deltarpm=0 in /etc/yum.conf. Refer to man yum.conf for more details.

| 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. |

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.
nm-cli has added features to configure mobile connections. For more detailed usage information, consult http://fedoraproject.org/wiki/Features/MoreMobileBroadband .

--os switch to report a different OS type to the gateway, and SecurID token support using libstoken.
named, the dhcpd server daemon, and related utilities. Documentation is available at http://bind10.isc.org/wiki and the BIND10 Guide.
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";
...
};
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.

stdlibstdlib 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.
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.
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>

| fox, a C++ based toolkit for developing graphical user interfaces easily and effectively. |
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.
JDK for this release. The inclusion of Java 8 and OpenJDK8 will allow developers to develop and test their applications for the next version of Java in parallel while everyone can continue using the stable Java 7 for daily use.

-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
-Wl,-u,__do_clear_bss resp. -Wl,-u,__do_copy_data.
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.
