Linux mint maya outdated ISOs

I just installed Linux mint maya xfce on my new IBM thinkpad T430.  I downloaded the latest ISO from linuxmint.com burned it to a DVD and went through the installation.  The DVD was about 795 MB in size and the installation went fairly smoothly.

Once the installation completed I did the obvious

apt-get update
apt-get upgrade

Boom this hits me now

This is quite a bit of updates to download right after burning and installing from an ISO only an hour ago.  Not sure why the ISO has not been kept up to date.
