This is a repeat question, but it appears to me the old answer isn't valid anymore.
Logged into the developers download page, using the cloud button, and I can see downloads for many things including the previous versions of the JavaScript API. I no longer see the web app builder. I'm looking for a copy of version 1.2 to narrow down a potential issue.
I've also checked https://developers.arcgis.com/web-appbuilder/ which has a download of the latest version (2.1), no older versions.
Are they still somewhere that I'm not checking?
Thanks.
