Title says it all really, and this post is more for my future self than anything else. So what is new in HTML5?

Here are some of my faves: video and audio tags, context menus and the sections are pretty nice. I can see myself using header, footer, article and nav pretty much in every website. The progress meter element is awesome, as are the new form inputs: datetime, date, month, week, time, number, email and url. Finally!!
