FreeBSD supported branches update

[FreeBSD Security Officer]

Hello Everyone,

The branches supported by the FreeBSD Security Officer have been updated to
reflect the EoL (end-of-life) of FreeBSD 6.4 and FreeBSD 8.0.  Since FreeBSD
6.4 was the last remaining supported release from the FreeBSD 6.x stable
branch, support for the FreeBSD 6.x stable branch has also ended.  The new
list of supported branches is below and at < http://security.freebsd.org/ >.

Users of FreeBSD 6.4 and 8.0 are advised to upgrade promptly to a newer release,
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 relevant release announcement.

The FreeBSD Ports Management Team wishes to remind users that November 30
is also the end of support for the Ports Collection for both FreeBSD 6.4
RELEASE and the FreeBSD 6.x STABLE branch.  Neither the infrastructure nor
individual ports are guaranteed to work on these FreeBSD versions after
that date.  A CVS tag will be created for users who cannot upgrade for some
reason, at which time these users are advised to stop tracking the latest
ports CVS repository and use the RELEASE_6_EOL tag instead.

The current supported branches and expected EoL dates are:
