Messaging Gateway

I notice that the current Brightmail release is using OpenSSH_3.5p1.   I beleive that OpenSSH is currently at 5.8  (http://en.wikipedia.org/wiki/OpenSSH).  Any plans to upgrade this?

There is an OpenSSH upgrade in an upcoming release later this year.  It will not be to the newest build, since we are tied to the stable build that pares with our OS environment, but it will be fully up to date on patches against all known vulnerabilities.

Is there a reference to a projected version upgrade.  I am currently doing certification and accreditation for this product and it will help with the remediation of particular findings.
