That Edition II thing was special for Solaris 2.3. It's a hardware support release. Early Solaris releases were a nightmare of patches and updates. I think Edition II first supported the SS5 and 20. They never used that "Edition" label for a later release, but just went with the date, just as jpstewart said.

In any way, Solaris 2.3 is only for the brave and strong. Solaris 2.4 with all patches and stuff applied makes for a more useful system and it will run Sun Workshop 3.0, which is nice.
