Ubuntu announced the release of 7.04 almost 18 months ago, on April 19, 2007. As with the earlier releases, Ubuntu committed to ongoing security and critical fixes for a period of 18 months. The support period is now nearing its end and Ubuntu 7.04 will reach end of life on Sunday, October 19th, 2008. At that time, Ubuntu Security Notices will no longer include information or updated packages for Ubuntu 7.04.

The supported upgrade path from Ubuntu 7.04 is via Ubuntu 7.10. Instructions and caveats for the upgrade may be found at https://help.ubuntu.com/community/GutsyUpgrades. Note that upgradesto version 8.04 LTS and beyond are only supported in multiple steps, via an upgrade first to 7.10, then to 8.04 LTS. Both Ubuntu 7.10 and Ubuntu 8.04 LTS continue to be actively supported with security updates and select high-impact bug fixes. All announcements of official security updates for Ubuntu releases are sent to the ubuntu-security-announce mailing list, information about which may be found at https://lists.ubuntu.com/mailman/listinfo/ubuntu-security-announce.

Since its launch in October 2004 Ubuntu has become one of the most highly regarded Linux distributions with millions of users in homes, schools, businesses and governments around the world. Ubuntu is Open Source software, costs nothing to download, and users are free to customise or alter their software in order to meet their needs.
