Hi
Not right now this is latest if new one is available you can check on SMP but as there are not much major changes in newer version SP05 -SP08 etc so I hope it might come later
you can check the help.sap documentation for newer changes as well
http://help.sap.com/saphelp_sm71_sp08/helpdata/en/45/51fbdbd4941803e10000000a1553f7/frameset.htm
hope this clarifies
Regards
Prakhar
