Editor's Draft updates

Simon,

I notice another update was published for the Editor's Draft of the Web Driver spec[1]. Is there an easy way for me to see the diff from previous versions? It looks like you are busy editing and I want to be able to keep up :).

I found the webdriver summary on W3.org [2], but it is out of date. I understood you were going to use github, but I may have misunderstood what you plan is.

Thanks
-John
