yes i know its on the partner center :) but you are not a partner yet...
I wish i could give you the release notes and i would if i could but our region latin america is running through a maintenience and i got no access to firmwares downloads(which means also the release notes i cannot see them)
I have to wait until next week before having access :( otherwise i would post them for you. Maybe some other forum user can colaborare with you and share them i mean one of another region which actually got access to those files...
Cheers
Carlos
