The W3C has published a Working Draft for version 2 of their widely referenced Web Content Accessibility Guidelines. Working Drafts are generally unstable and subject to change, so you should not start adjusting your accessibility techniques until it becomes a recommendation. The current recommendation is WCAG 1.0.
However, the Working Draft does give developers an opportunity to review possible advancements in the field of web accessibility and welcomes feedback on the document to w3c-wai-gl@w3.org.
