Ubuntu announced the release of 7.10 almost 18 months ago, on October
18, 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 7.10 will reach end of life
on Saturday, April 18, 2008. At that time, Ubuntu Security Notices will
no longer include information or updated packages for Ubuntu 7.10.

The supported upgrade path from Ubuntu 7.10 is via Ubuntu 8.04 LTS.
Instructions and caveats for the upgrade may be found at
https://help.ubuntu.com/community/HardyUpgrades. Note that upgrades
to version 8.10 and beyond are only supported in multiple steps, via
an upgrade first to 8.04 LTS, then to 8.10. Both Ubuntu 8.04 LTS and
Ubuntu 8.10 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
