slack 9.0 RC3 came out last week btw
But yes that is the one in current. Did you download from the slack ftp site?
Installing from floppies? I guess if you install a really minimal system that could work but if you want X floppies is....well.....pretty hard!
Look in the current "isolinux" dir and read the readme. That explains how to make an iso which you can burn onto a cd.
You can also download a slack current iso here
Those are fairly up to date.
Why can't you put it on a cd? No burner?
