Several months ago, the Fedora Board (in consultation with Red Hat Engineering) decided to increase the length of time that Fedora releases are supported, in terms of updates.
This decision was retroactively applied to Fedora Core 5, allowing it to remain a fully maintained release for several months longer than it would have under the old policy.
Fedora 7 will be released on Thursday May 24th, 2007.
Fedora Core 5 will reach its End of Life for updates on Friday June 29th, 2007.
In total, Fedora Core 5 will have had a lifespan of 15 months. For the sake of comparison, under the old policy, FC5 would have only had a lifespan of 11 months.
