They really are the RHEL Updates that the Upstream Vendor puts out about 
quarterly.  So they contain the security errata as you described but also 
all of the updated rpms that are part of the Upstream Vendor Update.  
These normally consist of bugfix rpms and or new feature rpms.  You need 
to read the Upstream Vendor Release notes to determine what they changed.  
These are located in the SL.documentation directory on the cd's or the ftp 
site and in /usr/share/doc/sl-release-4.?/ after a installation.
