W3C's HTML Working Group has announced that the "HTML5 specification has reached Last Call status." This's an extremely important milestone as Last Call is the point at which W3C thinks the group's work has reached a point of reasonable stability.
"Last Call is also essentially a call for all communities to confirm the technical soundness of the specification, after which the group will shift focus to gathering implementation experience and building a comprehensive test suite."
Microsoft staffers, along with many other individuals and 194 participants from 54 organizations - including Adobe, Google, Mozilla, Apple and Opera Software - all participate in the Working Group developing the specification for HTML5, the next version of the platform-neutral HyperText Markup Language standard used worldwide for rendering Web pages.
"HTML5 is the first new revision since HTML 4.01 was released in 1999, and will include built-in video and audio, a "canvas" element for two-dimensional graphics, new structural labels such as "article" to smooth programming, and a codified process to consistently interpret the hodgepodge styles of real-world Web pages, even when improperly coded."
