É pessoal segundo o anúncio abaixo, 31/07 é o fim da linha para o FreeBSD 8.1 e 8.2 no quesito segurança. Aconselha-se para quem tiver usando um desses releases, atualizar para a versão 8.3 pelo menos e continuar tendo suporte em segurança.  🙂

Hello Everyone,

On July 31st 2012, FreeBSD 8.1 and FreeBSD 8.2 will reach their End of
Life and will no longer be supported by the FreeBSD Security Team.
Users of FreeBSD 8.1 and 8.2 are strongly encouraged to upgrade to one
of the newer releases before the that date.
