HTML5
HTML5 improves interoperability and reduces development costs by making precise rules on how to handle all HTML elements, and how to recover from errors.
Some of the new features in HTML5 are functions for embedding audio, video, graphics, client-side data storage, and interactive documents. HTML5 also contains new elements like <nav>, <header>, <footer>, and <figure>.
The HTML5 working group includes AOL, Apple, Google, IBM, Microsoft, Mozilla, Nokia, Opera, and many hundreds of other vendors.
Note: HTML5 is not a W3C recommendation yet!
