Post date: Apr 13, 2014 12:36:32 PM
Today it's live, App Engine now supports finally naked domains. To enable naked domain support for your service simply go to your Google Developers Console. Select project, App Engine, Settings and there it is. You can now use naked domain when specifying DNS A and AAAA records, instead of using sub-domain with CNAME record. For more information see issue 777.
