Package Notes
The following sections contain information regarding software packages that have undergone significant changes for Fedora 25. For easier access, they are generally organized using the same groups that are shown in the installation system.
Sound Card Utility
The system-config-soundcard utility has been removed, due to numerous legacy design and implementation issues. Modern technologies, including udev and the HAL, have made most sound cards work out of the box. Any sound card not working out of the box should be reported as a bug . Preferences can still be fine-tuned within the desktop environment, using, among others, the PulseAudio tools.
Perl
Fedora 9 now includes Perl 5.10.0, the first "major" release update in perl5 in some time. The Perl interpreter itself is faster with a smaller memory footprint, and has several UTF-8 and threading improvements. The Perl installation is now relocatable, a blessing for systems administrators and operating system packagers. Perl 5.10.0 also adds a new smart match operator, a switch statement, named captures, state variables, and better error messages.

http://perldoc.perl.org/perldelta.html
Yum Changes
The installonlyn plugin functionality has been folded into the core yum package. The installonlypkgs and installonly_limit options are used by default to limit the system to retain only two kernel packages. You can adjust the package set or the number of packages, or disable the option entirely to match your preferences. More details is available in the man page for yum.conf.
The yum command now retries when it detects a lock. This function is useful if a daemon is checking for updates, or if you are running yum and one of its graphical frontends simultaneously.
The yum command now understands a cost parameter in its configuration file, which is the relative cost of accessing a software repository. It is useful for weighing one software repository's packages as greater or less than any other. The cost parameter defaults to 1000, with lower costs given priority.
In Fedora 9 Rawhide, the /etc/yum.repos.d/fedora-development.repo file has been changed to /etc/yum.repos.d/fedora-rawhide.repo. References to development in fedora-rawhide.repo have been changed to rawhide. Due to the way that RPM deals with configuration files, the existing /etc/yum.repos.d/fedora-development.repo file is saved as /etc/yum.repos.d/fedora-development.repo.rpmsave if it was previously modified. Users of the development repository may need to update scripts and custom configuration files to use the new name.
pam_mount
The pam_mount facility now uses a configuration file written in XML. The /etc/security/pam_mount.conf file will be converted to /etc/security/pam_mount.conf.xml during update with /usr/bin/convert_pam_mount_conf.pl, which removes all comments. Any per-user configuration files must be converted manually, with the conversion script if desired. A sample pam_mount.conf.xml file with detailed comments about the available options appears at /usr/share/doc/pam_mount-*/pam_mount.conf.xml.
TeXLive
TeXLive is a replacement for the old, unmaintained TeX package. It offers new style packages and fixes many security problems with the old distribution.
LTSP
The Linux Terminal Server Project (LTSP) has been included directly into Fedora 9. Work is ongoing. For the latest news and documentation, refer to:
http://k12linux.fedorahosted.org/
Utility Packages
The nautilus-open-terminal package now uses a GConf key to control its behavior when launched by right-clicking the Desktop. To enable its previous behavior, which opens the resulting terminal in the user's home directory, use this command:
gconftool-2 -s /apps/nautilus-open-terminal/desktop_opens_home_dir --type=bool true
The i810switch package has been removed. This functionality is now available through the xrandr command in the xorg-x11-server-utils package.
The evolution-exchange package replaces evolution-connector, and provides a capability under the old name.
The system-config-firewall and system-config-selinux packages replace system-config-security-level. The system-config-selinux package is part of the the policycoreutils-gui package.
pilot-link and HAL/PolicyKit Interaction
The pilot-link package now blacklists the visor module by default. Users are encouraged to try the direct USB access present in recent versions of pilot-link. This is enabled by passing the --port usb: option to the various pilot-link tools, instead of the serial devices used in the past (typically /dev/pilot or /dev/ttyUSB0, /dev/ttyUSB1, and so forth). For example:
pilot-xfer --port usb: --list
The hal-info and hal packages have been updated to correctly set permissions for the necessary USB devices using PolicyKit. If you have any existing manual configurations, revert the changes to avoid possible conflicts.
For further information, refer to the README.fedora included in the pilot-link package.
GIMP
Fedora 10 includes version 2.6 of the GNU Image Manipulation Program. This new version is designed to be backwards compatible, so existing third party plug-ins and scripts should continue to work -- with a minor caveat: The included Script-Fu Scheme interpreter doesn't accept variable definitions without an initial value anymore (which isn't compliant to the language standard anyway). Scripts included in Fedora packages should not have this problem, but if you use scripts from other sources, you may want to refer to the GIMP Release notes for more details and how you can fix scripts that have this problem.
