The Fedora Project releases updated software packages for Fedora throughout the support period of each version. Updated packages add new features, improve reliability, resolve bugs, or remove security vulnerabilities. To ensure the security of your system, update regularly, and as soon as possible after a security announcement is issued. Refer to Section 17.3, “Subscribing to Fedora Announcements and News” for information on the Fedora announcements services.

An update applet reminds you of updates when they are available. This applet is installed by default in Fedora. It checks for software updates from all configured repositories, and runs as a background service. It generates a notification message on the desktop if updates are found, and you can click the message to update your system's software.

To update packages from the command-line, use the yum utility. Type this command to begin a full update of your system with yum:

su -c 'yum update'

Enter the root password when prompted.

Refer to the Fedora System Administrator's Guide for more information on yum.
