XSS and Ajax Framework

What BP are prepared for the new AJAX Framework?

I have checked the note 1303362 and this [url|http://wiki.sdn.sap.com/wiki/display/ERPHCM/HOWTOGETRIDOFSPSTACKMISMATCHISSUES] and found that since BP ERP05 ESS 1.41 SP05 the NW Stack could be 701(start using ajax framework). But I dont know exactly how and what functions of ESS & MSS would work on the Ajax Framework.

Any information?

Thanks in advanced.
