[Hampshire] [hants] debian updates

hello there,

I don't use debian :) But, i do have a debian question :

I've downloaded what i think is the correct iso, its debian stable (4.0r6) etch. (cd 1 out of 20!).

In the Release file on cd, it suggests a release date of December 17th 2008.
Does this mean in a nutshell, updates/patches are included upto that date ?

This is for the sparc arch. btw, i only want a working tool chain.

thanks,

Isaac.
