5.x、6.1、6.0 が EoL になりました。

Security Officer のメールが来るまでスッカリ忘れてました。

The branches supported by the FreeBSD Security Officer have been updated
to reflect recent EoL (end-of-life) events.  The new list is below and
at .  FreeBSD 5.5, FreeBSD 6.1, and
FreeBSD 6.2 have `expired' and are no longer supported effective June 1,
2008.  Users of these releases are advised to upgrade promptly to FreeBSD
6.3 or FreeBSD 7.0, either by downloading an updated source tree and
building updates manually, or (for i386 and amd64 systems) using the
FreeBSD Update utility as described in the FreeBSD 6.3 and FreeBSD 7.0
release announcements.

詳細は FreeBSD Security Information を参照ください。しかし 5.x 系も終わりなんですねえ。まだ 4.x 系動いているところもあるというのに ^^;)。
