WCAG 2.0 Working Draft, the last call for reviewers to send their comments and suggestions on different issues for the new standard. The latest recommendation
WCAG 1.0 was published on May 1999, and I think the 2.0 recommendation will be ready by end 2008 since there should be first a Candidate Recommendation then Proposed Recommendation before make it final.
Web Content Accessibility Guidelines 2.0 (WCAG 2.0) covers a wide range of issues and recommendations for making Web content more accessible. This document contains principles, guidelines, and success criteria that define and explain the requirements for making Web-based information and applications accessible. "Accessible" means usable to a wide range of people with disabilities, including blindness and low vision, deafness and hearing loss, learning difficulties, cognitive limitations, limited movement, speech difficulties, photosensitivity and combinations of these. Following these guidelines will also make your Web content more accessible to the vast majority of users, including older users. It will also enable people to access Web content using many different devices - including a wide variety of assistive technologies.
