Upgrading from Squeeze testing to Squeeze stable

[Andrew Wood <a.j.w@me.com>]

Ive got a PC (this one) running Squeeze which was installed when sqeeeze 
was still 'testing'

Ive just run apt-get update & apt-get dist-upgrade which I thought would 
bring into line with the current squeeze stable yet there are still 
differences between this system and another new which Ive setup using a 
fresh download of the squeeze stable DVD .iso

For example the Grub boot splash is different, and Shotwell is present 
on the 'new' system but not on this one.

My sources.list file contains:


deb http://security.debian.org/ squeeze/updates main contrib

deb-src http://security.debian.org/ squeeze/updates main contrib

Any ideas why?

Thanks
