about new atlass document

I found that the new atlas's document(http://atlas.asp.net/docs/Default.aspx) had used atlas's updatepanel.
Where to download the new atlas's document's source code?

You can download the latest Atlas CTP drop from this URL:http://atlas.asp.net/default.aspx?tabid=47&subtabid=471

Hope this helps,

Scott

How to get it?

I'm not sure what you mean by "old document's source code". Can you explain more? What document are you referring to?

Thanks,
