differences / description / experiences autoyast with suse9.1 ?

Hi List, Before I dip my toes into automatic installation with suse9.1, is there a description on the way? Are there many differences from 9.0 to 9.1? Has anybody tried it, yet? With what results? (Btw: It would be nice to see a page "things what changed from version x to version x+1" in the description - and if the description is updated, date + version number would come in handy.) thanks for any information, Hella -- Top 100 things you don't want the sysadmin to say: 60.
