As Peter mentioned earlier, the new docs are out, on the ADN doc page.  If you've been using the Beta AJAX toolkit, please check the guide to migrating your AJAX code, found at the end of the AJAX Doc.  The Beta AJAX code will continue to run your existing S-Controls, but the new toolkit will provide a performance improvement, so check it out. The changes and additions to the API are listed here, and the complete 8.0 API doc is here. The entire Winter 07 release notes PDF is also available for your holiday reading.
