I don't remember the exact taxonomy, but the Gold CodeWarriors are pretty much hopeless for any code that's even remotely modern, so I use the Pro versions. I have CW 5, 6, 7 and 8. CW 6 is the last 68K version (I use CW 5 most of the time for 68K projects, however), and CW 7 is the first one to support Carbon. I don't remember when Mach-O capability was added (I think 8 ).

I don't know anything about the Windows or Java capabilities; I don't use those.
