On February 14, the World Wide Web Consortium (W3C) announced that the ‘Last Call’ for HTML5 would be May 2011, also announcing 2014 as the target for Recommendation. “Even as innovation continues, advancing HTML5 to Recommendation provides the entire Web ecosystem with a stable, tested, interoperable standard,” said Jeff Jaffe, W3C CEO.
Last Call indicates that the W3C thinks the standard’s features are set and that no new features will be added to the HTML5 spec. ‘Last Call’ is also a call for all communities to test the specification for technical soundness. Additionally, the W3C has initiated work on a comprehensive test suite to ensure high levels of interoperability.
HTML 4.01, released in 1999 was the last official update for HTML, making the Last Call a welcome announcement. Work on HTML5 began in 2007 with multiple features already being implemented in browsers today.
It should be noted though that the 2014 recommendation date only applies to the HTML5 specification and not to associated APIs.
