Or just go to this link and download it at the bottom of the page.
Yes that is the Minified WebAppViewer and NOT the Web AppBuilder Developer version. You can tell this by the fact that the widgets code is minified and that the JIMU.js/dijit folder only has one folder inside of it.
I've heard WAB (Developer Edition) is scheduled to be released on this Wed. Dec. 17th. I'm guessing there should be an announcement via the WAB (Developer Edition) Beta group as they said in their last email.
Simon, glad you found your email on this. I was going to mention that earlier but couldn't find my email to confirm, but the 17th was what stuck in my head also. At least that was the day comments on the beta page were to be closed. So the WAB dev version should be soon after that....we all hope.
Hello All! The Web AppBuilder Developer Edition will be released this Wednesday, December 17th. It will be downloadable from the Developer's site (from a new page dedicated to Web AppBuilder). Keep your eye out later this week for a blog that includes more details on the release and also a notification for the Web AppBuilder beta community.
