The World Weide Web Consortium (W3C) is calling for a broad review of HTML5, the next version of the Hypertext Markup Language used to describe webpages, as well as five related specifications that constitute the W3C Open Web Platform. Officially, this is known as entering the Last Call draft stage in which the HTML Working Group encourages people to comment on what's been made of HTML5 so far and whether or not they believe that technical requirements have been met.
This is a big step for HTML5, though not the last one. More changes could, and probably will come before it's final, particularly with the broad scope of HTML5.
"We now invite new voices to let us know whether these specifications address a broad set of needs," said Tim Berners-Lee, W3C Director. "This process for resolving dependencies with other groups is a central part of our mission of ensuring the web is well-designed, including being available to all. W3C staff will provide the HTML Working Group the support it needs to move forward, and to ensure that the specification meets W3C's commitments in areas such as accessibility, internationalization, security, and privacy."
If there are no substantive changes that need to be made, HTML5 will move up in the W3C Standards Process to Candidate Recommendation, and then onto W3C Recommendation at which point it will officially become a standard. W3C expects this to happen in 2014.
