From the fedora mailinglist:

As many of you are aware, our policy on the lifecycles of Fedora releases is:

"Fedora X will be maintained until about one month after Fedora X+2"

Fedora 7 was released on May 31st. Fedora Core 5 will reach its End of Life on Friday June 29th.

This was previously mentioned on fedora-announce-list on May 3rd, but is worth repeating.

Thank you,
