Today we released version 3.11 of the ArcGIS API for JavaScript. The optimizer has been updated to support the latest version, and the API & SDK is also available for download. Note that the downloads have moved to a new place.
Read the blog at http://blogs.esri.com/esri/arcgis/2014/10/06/arcgis-api-for-javascript-version-3-11-released/ .
Or for the complete details, read the Whats New at https://developers.arcgis.com/javascript/jshelp/whats_new.html.
For those of you not usually reading any of the above, please read at least the first item, that says:
"This is important if you’re upgrading from earlier versions!
To update your code for version 3.11 references, replace the following URLs:
change /3.10/js/dojo/
to /3.11/
(note the dropped “/js/dojo”) and change /3.10/js/esri/
to /3.11/esri/
(note the dropped “/js”).
