Hi Rob,
Actually the answer to that is no.  Sorry.
What Eric wrote is only true if you have installed 40rolling, or 
30rolling, or if you have changed your yum configuration to point to 4x, 
or 30x.

If you are on a regular 304, you will stay on 304 unless you manually 
change it.  The same goes for 40.

The documentation for changing to a new release is at
https://www.scientificlinux.org/documentation/howto/upgrade
which needs to get updated to include instructions for 4, but the steps 
are essentially

    1.   rpm -Uvh 
ftp://ftp.scientificlinux.org/linux/scientific/30x/i386/misc/RPMS/yum-conf-30x.SL.noarch.rpm
    2. yum update yum
    3. yum upgrade

If you are brave.  The detailed, easy does it steps, are on the web page.

The steps should be the same for 4.0 except replace 30x with 4x.
